ShareCompat
public final class ShareCompat
Extra helper functionality for sharing data between activities. ShareCompat provides functionality to extend the ACTION_SEND/ ACTION_SEND_MULTIPLE protocol and support retrieving more info about the activity that invoked a social sharing action. IntentBuilder provides helper functions for constructing a sharing intent that always includes data about the calling activity and app. This lets the called activity provide attribution for the app that shared content. Constructing an intent this way can be done in a method-chaining style. To obtain an IntentBuilder with info about your calling activity, use the static method from. IntentReader provides helper functions for parsing the defined extras within an ACTION_SEND or ACTION_SEND_MULTIPLE intent used to launch an activity. You can also obtain a Drawable for the caller's application icon and the application's localized label (the app's human-readable name). Social apps that enable sharing content are encouraged to use this information to call out the app that the content was shared from.

Constants
EXTRA_CALLING_ACTIVITY
public static final String EXTRA_CALLING_ACTIVITY = "androidx.core.app.EXTRA_CALLING_ACTIVITY"
Intent extra that stores the ComponentName of the calling activity for an ACTION_SEND intent. Instead of using this constant directly, consider using getCallingPackage or getCallingPackage.
EXTRA_CALLING_ACTIVITY_INTEROP
public static final String EXTRA_CALLING_ACTIVITY_INTEROP = "android.support.v4.app.EXTRA_CALLING_ACTIVITY"
Intent extra that stores the ComponentName of the calling activity for an ACTION_SEND intent. Note that this is only for interoperability between pre-1.0 AndroidX and AndroidX 1.1+ worlds. You are strongly encouraged to use getCallingPackage or getCallingPackage.
EXTRA_CALLING_PACKAGE
public static final String EXTRA_CALLING_PACKAGE = "androidx.core.app.EXTRA_CALLING_PACKAGE"
Intent extra that stores the name of the calling package for an ACTION_SEND intent. When an activity is started using startActivityForResult this is redundant info. (It is also provided by getCallingPackage.) Instead of using this constant directly, consider using getCallingPackage or getCallingPackage.
EXTRA_CALLING_PACKAGE_INTEROP
public static final String EXTRA_CALLING_PACKAGE_INTEROP = "android.support.v4.app.EXTRA_CALLING_PACKAGE"
Intent extra that stores the name of the calling package for an ACTION_SEND intent. When an activity is started using startActivityForResult this is redundant info. (It is also provided by getCallingPackage.) Note that this is only for interoperability between pre-1.0 AndroidX and AndroidX 1.1+ worlds. You are strongly encouraged to use getCallingPackage or getCallingPackage.
Public methods
public static voidconfigureMenuItem(
@NonNull MenuItem item,
@NonNull ShareCompat.IntentBuilder shareIntent
)
Configure a MenuItem to act as a sharing action.
This method will configure a ShareActionProvider to provide a more robust UI for selecting the target of the share. History will be tracked for each calling activity in a file named with the prefix ".sharecompat_" in the application's private data directory. If the application wishes to set this MenuItem to show as an action in the Action Bar it should use setShowAsAction to request that behavior in addition to calling this method.
During the calling activity's lifecycle, if data within the share intent must change the app should change that state in one of several ways:
- Call
invalidateOptionsMenu. If the app uses the Action Bar its menu will be recreated and rebuilt. If not, the activity will receive a call toonPrepareOptionsMenuthe next time the user presses the menu key to open the options menu panel. The activity can then call configureMenuItem again with a new or altered IntentBuilder to reconfigure the share menu item. - Keep a reference to the MenuItem object for the share item once it has been created and call configureMenuItem to update the associated sharing intent as needed.
| Parameters | |
|---|---|
@NonNull MenuItem item |
MenuItem to configure for sharing |
@NonNull ShareCompat.IntentBuilder shareIntent |
IntentBuilder with data about the content to share |
public static voidconfigureMenuItem(
@NonNull Menu menu,
@IdRes int menuItemId,
@NonNull ShareCompat.IntentBuilder shareIntent
)
Configure a menu item to act as a sharing action.
| Parameters | |
|---|---|
@NonNull Menu menu |
Menu containing the item to use for sharing |
@IdRes int menuItemId |
ID of the share item within menu |
@NonNull ShareCompat.IntentBuilder shareIntent |
IntentBuilder with data about the content to share |

getCallingActivity
public static @Nullable ComponentName getCallingActivity(@NonNull Activity calledActivity)
Retrieve the ComponentName of the activity that launched calledActivity from a share intent. Apps that provide social sharing functionality can use this to provide attribution for the app that shared the content.
Note: This data may have been provided voluntarily by the calling application. As such it should not be trusted for accuracy in the context of security or verification.
| Returns | |
|---|---|
@Nullable ComponentName |
ComponentName of the calling activity |
getCallingPackage
public static @Nullable String getCallingPackage(@NonNull Activity calledActivity)
Retrieve the name of the package that launched calledActivity from a share intent. Apps that provide social sharing functionality can use this to provide attribution for the app that shared the content.
Note: This data may have been provided voluntarily by the calling application. As such it should not be trusted for accuracy in the context of security or verification.
