How To Copy Paste Animation In Clipstudio

Android provides a powerful clipboard-based framework for copying and pasting. It supports both simple and complex data types, including text strings, complex data structures, text and binary stream data, and even application assets. Simple text data is stored directly in the clipboard, while circuitous data is stored as a reference that the pasting application resolves with a content provider. Copying and pasting works both inside an application and betwixt applications that implement the framework.

Since a part of the framework uses content providers, this topic assumes some familiarity with the Android Content Provider API, which is described in the topic Content Providers.

The Clipboard Framework

When you utilise the clipboard framework, you lot put data into a clip object, and then put the clip object on the system-wide clipboard. The prune object can take 1 of iii forms:

Text: A text cord. You put the string directly into the prune object, which you then put onto the clipboard. To paste the string, you lot go the prune object from the clipboard and copy the string to into your awarding's storage.
URI: A Uri object representing any course of URI. This is primarily for copying complex data from a content provider. To re-create data, you put a Uri object into a clip object and put the clip object onto the clipboard. To paste the data, you become the clip object, get the Uri object, resolve it to a data source such as a content provider, and copy the information from the source into your awarding's storage.
Intent: An Intent. This supports copying application shortcuts. To copy information, you create an Intent, put it into a clip object, and put the clip object onto the clipboard. To paste the information, you get the clip object and then copy the Intent object into your awarding's memory surface area.

The clipboard holds only ane clip object at a time. When an application puts a prune object on the clipboard, the previous prune object disappears.

If y'all desire to allow users to paste data into your application, you lot don't accept to handle all types of data. You can examine the data on the clipboard before you requite users the selection to paste it. Also having a certain data form, the prune object too contains metadata that tells yous what MIME type or types are bachelor. This metadata helps y'all decide if your awarding can do something useful with the clipboard data. For example, if you take an application that primarily handles text, y'all may want to ignore clip objects that contain a URI or Intent.

You lot may too want to allow users to paste text regardless of the grade of information on the clipboard. To do this, you tin can force the clipboard data into a text representation, and and so paste this text. This is described in the section Coercing the clipboard to text.

Clipboard Classes

This department describes the classes used by the clipboard framework.

ClipboardManager

In the Android system, the system clipboard is represented by the global ClipboardManager class. Y'all do not instantiate this class direct; instead, you get a reference to it by invoking getSystemService(CLIPBOARD_SERVICE).

ClipData, ClipData.Item, and ClipDescription

To add together information to the clipboard, you create a ClipData object that contains both a description of the data and the information itself. The clipboard holds simply 1 ClipData at a time. A ClipData contains a ClipDescription object and ane or more ClipData.Item objects.

A ClipDescription object contains metadata about the clip. In particular, it contains an array of available MIME types for the clip's data. Additionally, on Android 12 (API level 31) and higher, the metadata includes information about whether the object contains stylized text and almost the type of text in the object. When you put a clip on the clipboard, this information is available to pasting applications, which tin can examine it to see if they tin handle the clip information.

A ClipData.Item object contains the text, URI, or Intent information:

Text: A CharSequence.
URI: A Uri. This usually contains a content provider URI, although whatever URI is allowed. The application that provides the data puts the URI on the clipboard. Applications that want to paste the information get the URI from the clipboard and utilize it to admission the content provider (or other data source) and call back the data.
Intent: An Intent. This information blazon allows you to copy an awarding shortcut to the clipboard. Users can then paste the shortcut into their applications for after utilize.

You can add together more one ClipData.Detail object to a clip. This allows users to copy and paste multiple selections as a single clip. For case, if you lot have a list widget that allows the user to select more than ane detail at a fourth dimension, yous tin copy all the items to the clipboard at once. To do this, you create a dissever ClipData.Item for each listing particular, and then yous add the ClipData.Item objects to the ClipData object.

ClipData convenience methods

The ClipData course provides static convenience methods for creating a ClipData object with a unmarried ClipData.Particular object and a unproblematic ClipDescription object:

newPlainText(characterization, text): Returns a ClipData object whose single ClipData.Item object contains a text string. The ClipDescription object's characterization is prepare to label. The unmarried MIME type in ClipDescription is MIMETYPE_TEXT_PLAIN.
Apply newPlainText() to create a clip from a text cord.
newUri(resolver, label, URI): Returns a ClipData object whose single ClipData.Item object contains a URI. The ClipDescription object's label is set up to characterization. If the URI is a content URI (Uri.getScheme() returns content:), the method uses the ContentResolver object provided in resolver to recall the available MIME types from the content provider and store them in ClipDescription. For a URI that is not a content: URI, the method sets the MIME type to MIMETYPE_TEXT_URILIST.
Apply newUri() to create a clip from a URI, particularly a content: URI.
newIntent(label, intent): Returns a ClipData object whose single ClipData.Particular object contains an Intent. The ClipDescription object's label is set up to label. The MIME blazon is fix to MIMETYPE_TEXT_INTENT.
Utilize newIntent() to create a clip from an Intent object.

Coercing the clipboard data to text

Even if your application only handles text, y'all can copy non-text data from the clipboard past converting it with the method ClipData.Particular.coerceToText().

This method converts the data in ClipData.Particular to text and returns a CharSequence. The value that ClipData.Item.coerceToText() returns is based on the course of data in ClipData.Item:

Text

If ClipData.Item is text (getText() is non goose egg), coerceToText() returns the text.

URI

If ClipData.Item is a URI (getUri() is not zero), coerceToText() tries to utilise it as a content URI:

If the URI is a content URI and the provider can return a text stream, coerceToText() returns a text stream.
If the URI is a content URI but the provider does not offering a text stream, coerceToText() returns a representation of the URI. The representation is the aforementioned as that returned by Uri.toString().
If the URI is non a content URI, coerceToText() returns a representation of the URI. The representation is the same as that returned by Uri.toString().

Intent

If ClipData.Particular is an Intent (getIntent() is non nothing), coerceToText() converts it to an Intent URI and returns it. The representation is the same every bit that returned by Intent.toUri(URI_INTENT_SCHEME).

The clipboard framework is summarized in Figure 1. To copy data, an application puts a ClipData object on the ClipboardManager global clipboard. The ClipData contains one or more than ClipData.Detail objects and 1 ClipDescription object. To paste information, an application gets the ClipData, gets its MIME type from the ClipDescription, and gets the data either from the ClipData.Particular or from the content provider referred to past ClipData.Item.

Copying to the Clipboard

As described previously, to copy information to the clipboard you go a handle to the global ClipboardManager object, create a ClipData object, add a ClipDescription and one or more ClipData.Item objects to information technology, and add together the finished ClipData object to the ClipboardManager object. This is described in detail in the following procedure:

If you are copying information using a content URI, ready a content provider.
The Note Pad sample awarding is an case of using a content provider for copying and pasting. The NotePadProvider class implements the content provider. The NotePad class defines a contract betwixt the provider and other applications, including the supported MIME types.

Get the system clipboard:

Kotlin

when(menuItem.itemId) {     ...     R.id.menu_copy -> { // if the user selects copy         // Gets a handle to the clipboard service.         val clipboard = getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager     } }

Java

...  // if the user selects re-create case R.id.menu_copy:  // Gets a handle to the clipboard service. ClipboardManager clipboard = (ClipboardManager)         getSystemService(Context.CLIPBOARD_SERVICE);

Copy the information to a new ClipData object:

For text

Kotlin

// Creates a new text prune to put on the clipboard val clip: ClipData = ClipData.newPlainText("simple text", "Hello, World!")

Java

// Creates a new text clip to put on the clipboard ClipData prune = ClipData.newPlainText("simple text", "Hello, World!");

For a URI

This snippet constructs a URI by encoding a tape ID onto the content URI for the provider. This technique is covered in more detail in the section Encoding an identifier on the URI:

Kotlin

// Creates a Uri based on a base of operations Uri and a tape ID based on the contact's last name // Declares the base URI cord const val CONTACTS = "content://com.case.contacts"  // Declares a path string for URIs that you utilise to re-create data const val COPY_PATH = "/copy"  // Declares the Uri to paste to the clipboard val copyUri: Uri = Uri.parse("$CONTACTS$COPY_PATH/$lastName")  ...  // Creates a new URI clip object. The arrangement uses the anonymous getContentResolver() object to // go MIME types from provider. The prune object's label is "URI", and its data is // the Uri previously created. val prune: ClipData = ClipData.newUri(contentResolver, "URI", copyUri)

Java

// Creates a Uri based on a base Uri and a record ID based on the contact'due south last name // Declares the base of operations URI string individual static concluding String CONTACTS = "content://com.example.contacts";  // Declares a path cord for URIs that you use to copy information private static final Cord COPY_PATH = "/re-create";  // Declares the Uri to paste to the clipboard Uri copyUri = Uri.parse(CONTACTS + COPY_PATH + "/" + lastName);  ...  // Creates a new URI clip object. The system uses the anonymous getContentResolver() object to // get MIME types from provider. The clip object's characterization is "URI", and its data is // the Uri previously created. ClipData clip = ClipData.newUri(getContentResolver(), "URI", copyUri);

For an Intent

This snippet constructs an Intent for an application and then puts it in the prune object:

Kotlin

// Creates the Intent val appIntent = Intent(this, com.example.demo.myapplication::grade.java)  ...  // Creates a prune object with the Intent in it. Its label is "Intent" and its data is // the Intent object created previously val clip: ClipData = ClipData.newIntent("Intent", appIntent)

Java

// Creates the Intent Intent appIntent = new Intent(this, com.example.demo.myapplication.class);  ...  // Creates a prune object with the Intent in it. Its label is "Intent" and its data is // the Intent object created previously ClipData clip = ClipData.newIntent("Intent", appIntent);

Put the new clip object on the clipboard:

Kotlin

// Set the clipboard's primary clip. clipboard.setPrimaryClip(prune)

Java

// Set the clipboard's primary clip. clipboard.setPrimaryClip(prune);

Pasting from the Clipboard

Equally described previously, you lot paste information from the clipboard by getting the global clipboard object, getting the clip object, looking at its data, and if possible copying the data from the clip object to your own storage. This section explains in detail how to paste the three forms of clipboard data.

Pasting plain text

To paste obviously text, first get the global clipboard and verify that it can render patently text. Then get the clip object and copy its text to your own storage using getText(), as described in the following procedure:

Go the global ClipboardManager object using getSystemService(CLIPBOARD_SERVICE). As well declare a global variable to contain the pasted text:

Kotlin

var clipboard = getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager var pasteData: String = ""

Java

ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); String pasteData = "";

Next, determine if you should enable or disable the "paste" choice in the current Action. You should verify that the clipboard contains a clip and that you can handle the type of data represented by the clip:

Kotlin

// Gets the ID of the "paste" menu item val pasteItem: MenuItem = menu.findItem(R.id.menu_paste)  // If the clipboard doesn't contain data, disable the paste card item. // If it does contain data, decide if you can handle the data. pasteItem.isEnabled = when {     !clipboard.hasPrimaryClip() -> {         imitation     }     !(clipboard.primaryClipDescription.hasMimeType(MIMETYPE_TEXT_PLAIN)) -> {         // This disables the paste bill of fare item, since the clipboard has data only it is not plain text         fake     }     else -> {         // This enables the paste card detail, since the clipboard contains evidently text.         truthful     } }

Java

// Gets the ID of the "paste" menu item MenuItem pasteItem = menu.findItem(R.id.menu_paste);  // If the clipboard doesn't contain data, disable the paste bill of fare item. // If it does contain data, decide if you can handle the data. if (!(clipboard.hasPrimaryClip())) {      pasteItem.setEnabled(imitation);  } else if (!(clipboard.getPrimaryClipDescription().hasMimeType(MIMETYPE_TEXT_PLAIN))) {      // This disables the paste menu item, since the clipboard has information but it is non obviously text     pasteItem.setEnabled(imitation); } else {      // This enables the paste menu item, since the clipboard contains patently text.     pasteItem.setEnabled(truthful); }

Copy the data from the clipboard. This point in the plan is only reachable if the "paste" menu item is enabled, so you can presume that the clipboard contains plainly text. You do non notwithstanding know if it contains a text string or a URI that points to plain text. The post-obit snippet tests this, simply it only shows the lawmaking for handling plain text:

Kotlin

when (menuItem.itemId) {     ...     R.id.menu_paste -> {    // Responds to the user selecting "paste"         // Examines the detail on the clipboard. If getText() does non return naught, the clip item         // contains the text. Assumes that this application tin only handle one item at a time.         val detail = clipboard.primaryClip.getItemAt(0)          // Gets the clipboard as text.         pasteData = detail.text          render if (pasteData != zilch) {             // If the cord contains information, so the paste performance is done             true         } else {             // The clipboard does non contain text.             // If it contains a URI, attempts to go data from it             val pasteUri: Uri? = item.uri              if (pasteUri != nix) {                 // If the URI contains something, try to become text from it                  // calls a routine to resolve the URI and get data from it. This routine is not                 // presented here.                 pasteData = resolveUri(pasteUri)                 true             } else {                  // Something is incorrect. The MIME type was plain text, but the clipboard does non                 // contain either text or a Uri. Report an error.                 Log.eastward(TAG,"Clipboard contains an invalid data blazon")                 fake             }         }     } }

Java

// Responds to the user selecting "paste" example R.id.menu_paste:  // Examines the item on the clipboard. If getText() does non return null, the prune detail contains the // text. Assumes that this awarding tin only handle 1 item at a fourth dimension.  ClipData.Item particular = clipboard.getPrimaryClip().getItemAt(0);  // Gets the clipboard equally text. pasteData = particular.getText();  // If the string contains data, then the paste operation is washed if (pasteData != zippo) {     return true;  // The clipboard does not contain text. If it contains a URI, attempts to go data from it } else {     Uri pasteUri = particular.getUri();      // If the URI contains something, try to get text from it     if (pasteUri != goose egg) {          // calls a routine to resolve the URI and get data from it. This routine is not         // presented here.         pasteData = resolveUri(Uri);         return truthful;     } else {          // Something is incorrect. The MIME blazon was manifestly text, but the clipboard does not contain either         // text or a Uri. Report an mistake.         Log.due east(TAG, "Clipboard contains an invalid data type");         return false;     } }

Pasting information from a content URI

If the ClipData.Item object contains a content URI and yous have determined that y'all can handle 1 of its MIME types, create a ContentResolver and and then phone call the appropriate content provider method to retrieve the data.

The post-obit procedure describes how to go information from a content provider based on a content URI on the clipboard. It checks that a MIME type that the application tin utilize is available from the provider:

Declare a global variable to contain the MIME type:

Kotlin

// Declares a MIME type abiding to friction match against the MIME types offered past the provider const val MIME_TYPE_CONTACT = "vnd.android.cursor.item/vnd.case.contact"

Java

// Declares a MIME blazon abiding to friction match against the MIME types offered by the provider public static final String MIME_TYPE_CONTACT = "vnd.android.cursor.item/vnd.case.contact";

Get the global clipboard. Also get a content resolver then you can admission the content provider:

Kotlin

// Gets a handle to the Clipboard Manager val clipboard = getSystemService(Context.CLIPBOARD_SERVICE) equally ClipboardManager  // Gets a content resolver instance val cr = contentResolver

Java

// Gets a handle to the Clipboard Manager ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);  // Gets a content resolver instance ContentResolver cr = getContentResolver();

Get the primary clip from the clipboard, and get its contents every bit a URI:

Kotlin

// Gets the clipboard data from the clipboard val clip: ClipData? = clipboard.primaryClip  clip?.run {      // Gets the first item from the clipboard data     val item: ClipData.Item = getItemAt(0)      // Tries to go the detail's contents as a URI     val pasteUri: Uri? = item.uri

Java

// Gets the clipboard data from the clipboard ClipData clip = clipboard.getPrimaryClip();  if (clip != null) {      // Gets the get-go item from the clipboard information     ClipData.Item detail = clip.getItemAt(0);      // Tries to get the particular's contents as a URI     Uri pasteUri = item.getUri();

Test to see if the URI is a content URI by calling getType(Uri). This method returns null if Uri does not point to a valid content provider:

Kotlin

                  // If the clipboard contains a URI reference     pasteUri?.let {          // Is this a content URI?         val uriMimeType: Cord? = cr.getType(it)

Java

                  // If the clipboard contains a URI reference     if (pasteUri != null) {          // Is this a content URI?         String uriMimeType = cr.getType(pasteUri);

Examination to see if the content provider supports a MIME type that the current awarding understands. If it does, call ContentResolver.query() to get the data. The return value is a Cursor:

Kotlin

                  // If the return value is not null, the Uri is a content Uri         uriMimeType?.takeIf {              // Does the content provider offer a MIME type that the electric current application tin apply?             it == MIME_TYPE_CONTACT         }?.apply {              // Get the data from the content provider.             cr.query(pasteUri, null, aught, cipher, null)?.use { pasteCursor ->                  // If the Cursor contains data, move to the first record                 if (pasteCursor.moveToFirst()) {                      // go the data from the Cursor hither. The code volition vary according to the                     // format of the data model.                 }                  // Kotlin `use` will automatically close the Cursor             }         }     } }

Java

                  // If the return value is not null, the Uri is a content Uri         if (uriMimeType != nada) {              // Does the content provider offer a MIME type that the current application can use?             if (uriMimeType.equals(MIME_TYPE_CONTACT)) {                  // Get the information from the content provider.                 Cursor pasteCursor = cr.query(uri, nada, null, nix, nil);                  // If the Cursor contains data, move to the first record                 if (pasteCursor != null) {                     if (pasteCursor.moveToFirst()) {                      // get the information from the Cursor here. The code will vary according to the                     // format of the data model.                     }                 }                  // close the Cursor                 pasteCursor.close();              }          }      } }

Pasting an Intent

To paste an Intent, offset get the global clipboard. Examine the ClipData.Item object to run across if it contains an Intent. Then phone call getIntent() to re-create the Intent to your own storage. The following snippet demonstrates this:

Kotlin

// Gets a handle to the Clipboard Manager val clipboard = getSystemService(Context.CLIPBOARD_SERVICE) every bit ClipboardManager  // Checks to run across if the clip item contains an Intent, by testing to run across if getIntent() returns null val pasteIntent: Intent? = clipboard.primaryClip?.getItemAt(0)?.intent  if (pasteIntent != goose egg) {      // handle the Intent  } else {      // ignore the clipboard, or upshot an error if your application was expecting an Intent to be     // on the clipboard }

Java

// Gets a handle to the Clipboard Managing director ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);  // Checks to see if the clip item contains an Intent, by testing to see if getIntent() returns null Intent pasteIntent = clipboard.getPrimaryClip().getItemAt(0).getIntent();  if (pasteIntent != aught) {      // handle the Intent  } else {      // ignore the clipboard, or issue an error if your application was expecting an Intent to be     // on the clipboard }

System notification shown when your app accesses clipboard data

On Android 12 (API level 31) and higher, the organization usually shows a toast message when your app calls getPrimaryClip(). The text within the message contains the following format:

          APP          pasted from your clipboard

The system doesn't show a toast message when your app does ane of the following:

Accesses ClipData from your own app.
Repeatedly accesses ClipData from a specific app. The toast appears only when your app accesses the data from that app for the first time.
Retrieves metadata for the clip object, such as by calling getPrimaryClipDescription(), instead of getPrimaryClip().

Using Content Providers to Copy Circuitous Data

Content providers back up copying complex data such equally database records or file streams. To copy the information, y'all put a content URI on the clipboard. Pasting applications then get this URI from the clipboard and use information technology to retrieve database data or file stream descriptors.

Since the pasting application only has the content URI for your data, it needs to know which piece of data to retrieve. You tin provide this information by encoding an identifier for the data on the URI itself, or you tin provide a unique URI that will return the information you want to re-create. Which technique yous choose depends on the organization of your data.

The following sections describe how to set URIs, how to provide complex information, and how to provide file streams. The descriptions assume that you are familiar with the full general principles of content provider blueprint.

Encoding an identifier on the URI

A useful technique for copying data to the clipboard with a URI is to encode an identifier for the information on the URI itself. Your content provider can and so go the identifier from the URI and utilize information technology to remember the information. The pasting application doesn't have to know that the identifier exists; all it has to practice is get your "reference" (the URI plus the identifier) from the clipboard, requite information technology your content provider, and become dorsum the information.

Y'all usually encode an identifier onto a content URI past concatenating it to the end of the URI. For example, suppose you ascertain your provider URI as the following string:

"content://com.example.contacts"

If yous want to encode a name onto this URI, you would employ the following snippet:

Kotlin

val uriString = "content://com.instance.contacts/Smith"  // uriString now contains content://com.instance.contacts/Smith.  // Generates a uri object from the string representation val copyUri = Uri.parse(uriString)

Java

String uriString = "content://com.example.contacts" + "/" + "Smith";  // uriString at present contains content://com.case.contacts/Smith.  // Generates a uri object from the string representation Uri copyUri = Uri.parse(uriString);

If you are already using a content provider, yous may desire to add a new URI path that indicates the URI is for copying. For example, suppose yous already have the following URI paths:

"content://com.example.contacts"/people "content://com.example.contacts"/people/detail "content://com.instance.contacts"/people/images

Yous could add another path that is specific to copy URIs:

"content://com.example.contacts/copying"

Y'all could and so detect a "copy" URI past design-matching and handle it with code that is specific for copying and pasting.

You lot normally use the encoding technique if you're already using a content provider, internal database, or internal table to organize your data. In these cases, you have multiple pieces of data you want to copy, and presumably a unique identifier for each piece. In response to a query from the pasting application, you can look upwardly the data by its identifier and render information technology.

If y'all don't have multiple pieces of information, so you probably don't need to encode an identifier. You can simply apply a URI that is unique to your provider. In response to a query, your provider would render the data it currently contains.

Getting a single record by ID is used in the Note Pad sample application to open a notation from the notes list. The sample uses the _id field from an SQL database, but y'all tin have whatever numeric or character identifier you desire.

Copying data structures

You prepare a content provider for copying and pasting circuitous data as a subclass of the ContentProvider component. You should as well encode the URI you put on the clipboard so that it points to the verbal record you want to provide. In add-on, you have to consider the existing state of your application:

If yous already have a content provider, you lot can add together to its functionality. You may just need to modify its query() method to handle URIs coming from applications that desire to paste data. You will probably want to modify the method to handle a "copy" URI pattern.
If your application maintains an internal database, you lot may want to move this database into a content provider to facilitate copying from it.
If you are not currently using a database, you lot can implement a simple content provider whose sole purpose is to offering information to applications that are pasting from the clipboard.

In the content provider, you lot will want to override at to the lowest degree the following methods:

query(): Pasting applications will assume that they tin can get your data by using this method with the URI you put on the clipboard. To back up copying, you should accept this method detect URIs that contain a special "copy" path. Your application can so create a "copy" URI to put on the clipboard, containing the copy path and a pointer to the exact tape you want to re-create.
getType(): This method should return the MIME blazon or types for the data y'all intend to copy. The method newUri() calls getType() in society to put the MIME types into the new ClipData object.
MIME types for complex data are described in the topic Content Providers.

Notice that you don't take to have any of the other content provider methods such as insert() or update(). A pasting application but needs to become your supported MIME types and copy information from your provider. If you already have these methods, they won't interfere with re-create operations.

The following snippets demonsrate how to ready your application to copy complex information:

In the global constants for your application, declare a base of operations URI string and a path that identifies URI strings you lot are using to re-create data. As well declare a MIME blazon for the copied data:

Kotlin

// Declares the base URI string private const val CONTACTS = "content://com.instance.contacts"  // Declares a path string for URIs that you use to copy data private const val COPY_PATH = "/copy"  // Declares a MIME type for the copied data const val MIME_TYPE_CONTACT = "vnd.android.cursor.particular/vnd.instance.contact"

Java

// Declares the base URI string private static final String CONTACTS = "content://com.example.contacts";  // Declares a path string for URIs that you use to copy information private static final Cord COPY_PATH = "/copy";  // Declares a MIME type for the copied data public static last String MIME_TYPE_CONTACT = "vnd.android.cursor.item/vnd.case.contact";

In the Activity from which users copy information, set up the lawmaking to copy data to the clipboard. In response to a re-create asking, put the URI on the clipboard:

Kotlin

class MyCopyActivity : Action() {      ...  when(item.itemId) {     R.id.menu_copy -> { // The user has selected a name and is requesting a copy.         // Appends the terminal name to the base URI         // The proper name is stored in "lastName"         uriString = "$CONTACTS$COPY_PATH/$lastName"          // Parses the string into a URI         val copyUri: Uri? = Uri.parse(uriString)          // Gets a handle to the clipboard service.         val clipboard = getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager          val prune: ClipData = ClipData.newUri(contentResolver, "URI", copyUri)          // Set the clipboard's primary prune.         clipboard.setPrimaryClip(clip)     } }

Java

public class MyCopyActivity extends Activity {      ...  // The user has selected a name and is requesting a copy. instance R.id.menu_copy:      // Appends the last name to the base URI     // The name is stored in "lastName"     uriString = CONTACTS + COPY_PATH + "/" + lastName;      // Parses the cord into a URI     Uri copyUri = Uri.parse(uriString);      // Gets a handle to the clipboard service.     ClipboardManager clipboard = (ClipboardManager)         getSystemService(Context.CLIPBOARD_SERVICE);      ClipData clip = ClipData.newUri(getContentResolver(), "URI", copyUri);      // Gear up the clipboard'due south primary prune.     clipboard.setPrimaryClip(clip);

In the global telescopic of your content provider, create a URI matcher and add a URI pattern that volition match URIs you put on the clipboard:

Kotlin

// A Uri Match object that simplifies matching content URIs to patterns. private val sUriMatcher = UriMatcher(UriMatcher.NO_MATCH).use {      // Adds a matcher for the content URI. It matches     // "content://com.instance.contacts/copy/*"     addURI(CONTACTS, "names/*", GET_SINGLE_CONTACT) }  // An integer to use in switching based on the incoming URI pattern private const val GET_SINGLE_CONTACT = 0  ...  course MyCopyProvider : ContentProvider() {     ... }

Coffee

public grade MyCopyProvider extends ContentProvider {      ...  // A Uri Friction match object that simplifies matching content URIs to patterns. individual static terminal UriMatcher sURIMatcher = new UriMatcher(UriMatcher.NO_MATCH);  // An integer to use in switching based on the incoming URI design individual static final int GET_SINGLE_CONTACT = 0;  ...  // Adds a matcher for the content URI. Information technology matches // "content://com.example.contacts/copy/*" sUriMatcher.addURI(CONTACTS, "names/*", GET_SINGLE_CONTACT);

Prepare up the query() method. This method can handle unlike URI patterns, depending on how you code it, but only the pattern for the clipboard copying operation is shown:

Kotlin

// Sets up your provider'southward query() method. override fun query(         uri: Uri,         project: Array<out Cord>?,         selection: String?,         selectionArgs: Array<out String>?,         sortOrder: String? ): Cursor? {      ...      // when based on the incoming content URI     when(sUriMatcher.match(uri)) {          GET_SINGLE_CONTACT -> {              // query and render the contact for the requested proper name. Hither y'all would decode             // the incoming URI, query the data model based on the last name, and render the result             // equally a Cursor.         }     }      ...  }

Java

// Sets upwards your provider'south query() method. public Cursor query(Uri uri, String[] project, String selection, Cord[] selectionArgs,     String sortOrder) {      ...      // Switch based on the incoming content URI     switch (sUriMatcher.lucifer(uri)) {      instance GET_SINGLE_CONTACT:          // query and return the contact for the requested name. Here you lot would decode         // the incoming URI, query the information model based on the terminal name, and return the result         // as a Cursor.      ...  }

Set up the getType() method to return an advisable MIME type for copied information:

Kotlin

// Sets up your provider'due south getType() method. override fun getType(uri: Uri): String? {     ...      return when(sUriMatcher.match(uri)) {         GET_SINGLE_CONTACT -> MIME_TYPE_CONTACT         ...     } }

Coffee

// Sets up your provider's getType() method. public String getType(Uri uri) {     ...      switch (sUriMatcher.match(uri)) {     example GET_SINGLE_CONTACT:         render (MIME_TYPE_CONTACT);     ...     } }

The section Pasting information from a content URI describes how to get a content URI from the clipboard and use it to get and paste data.

Copying data streams

You can re-create and paste large amounts of text and binary information as streams. The data tin take forms such as the following:

Files stored on the actual device.
Streams from sockets.
Large amounts of information stored in a provider's underlying database organization.

A content provider for data streams provides access to its data with a file descriptor object such equally AssetFileDescriptor instead of a Cursor object. The pasting application reads the data stream using this file descriptor.

To gear up up your application to copy a data stream with a provider, follow these steps:

Set upwardly a content URI for the data stream you lot are putting on the clipboard. Options for doing this include the following:
- Encode an identifier for the data stream onto the URI, equally described in the section Encoding an identifier on the URI, and then maintain a table in your provider that contains identifiers and the corresponding stream name.
- Encode the stream name directly on the URI.
- Utilize a unique URI that e'er returns the current stream from the provider. If y'all utilize this option, you have to retrieve to update your provider to point to a different stream whenever you lot re-create the stream to the clipboard via the URI.
Provide a MIME blazon for each type of information stream you plan to offer. Pasting applications need this information to decide if they can paste the information on the clipboard.
Implement 1 of the ContentProvider methods that returns a file descriptor for a stream. If you encode identifiers on the content URI, use this method to determine which stream to open.
To copy the data stream to the clipboard, construct the content URI and place information technology on the clipboard.

To paste a data stream, an awarding gets the clip from the clipboard, gets the URI, and uses it in a telephone call to a ContentResolver file descriptor method that opens the stream. The ContentResolver method calls the corresponding ContentProvider method, passing information technology the content URI. Your provider returns the file descriptor to ContentResolver method. The pasting application then has the responsibility to read the data from the stream.

The following listing shows the most important file descriptor methods for a content provider. Each of these has a corresponding ContentResolver method with the string "Descriptor" appended to the method proper noun; for case, the ContentResolver analog of openAssetFile() is openAssetFileDescriptor():

openTypedAssetFile(): This method should render an nugget file descriptor, but only if the provided MIME blazon is supported past the provider. The caller (the application doing the pasting) provides a MIME type pattern. The content provider (of the awarding that has copied a URI to the clipboard) returns an AssetFileDescriptor file handle if it can provide that MIME blazon, or throws an exception if it tin can not.
This method handles subsections of files. You tin employ information technology to read assets that the content provider has copied to the clipboard.
openAssetFile(): This method is a more general class of openTypedAssetFile(). It does non filter for allowed MIME types, merely it can read subsections of files.
openFile(): This is a more full general course of openAssetFile(). It tin't read subsections of files.

You can optionally utilise the openPipeHelper() method with your file descriptor method. This allows the pasting awarding to read the stream information in a background thread using a piping. To utilise this method, you need to implement the ContentProvider.PipeDataWriter interface. An instance of doing this is given in the Note Pad sample application, in the openTypedAssetFile() method of NotePadProvider.coffee.

Designing Effective Copy/Paste Functionality

To design effective copy and paste functionality for your application, remember these points:

At any time, there is only one clip on the clipboard. A new copy performance by any application in the system overwrites the previous prune. Since the user may navigate abroad from your application and exercise a copy earlier returning, you can't assume that the clipboard contains the clip that the user previously copied in your application.
The intended purpose of multiple ClipData.Item objects per clip is to support copying and pasting of multiple selections rather than different forms of reference to a single choice. You lot usually want all of the ClipData.Particular objects in a clip to have the aforementioned form, that is, they should all exist uncomplicated text, content URI, or Intent, but not a mixture.
When you provide information, you can offer different MIME representations. Add the MIME types you back up to the ClipDescription, and and then implement the MIME types in your content provider.
When y'all go data from the clipboard, your application is responsible for checking the available MIME types and and then deciding which one, if whatsoever, to utilize. Fifty-fifty if there is a clip on the clipboard and the user requests a paste, your application is not required to practise the paste. You lot should do the paste if the MIME blazon is compatible. You may choose to coerce the data on the clipboard to text using coerceToText() if you choose. If your application supports more than one of the bachelor MIME types, y'all can allow the user to cull which one to use.
