@RequiresPermission(value = "android.permission.EXECUTE_APP_FUNCTIONS", conditional = true)
public final @NonNull ExecuteAppFunctionResponse executeAppFunction(@NonNull ExecuteAppFunctionRequest request)

Execute the app function.

This method matches the platform behavior defined in android.app.appfunctions.AppFunctionManager.executeAppFunction.

public static final AppFunctionManagerCompat getInstance(@NonNull Context context)

Gets an instance of AppFunctionManagerCompat if the AppFunction feature is supported.

Support is determined by verifying the SDK version is at least 33 and if the device implements the App Functions extension library.

public final boolean isAppFunctionEnabled(@NonNull String functionId)

Checks if functionId in the caller's package is enabled.

This method matches the platform behavior defined in android.app.appfunctions.AppFunctionManager.isAppFunctionEnabled.

@RequiresPermission(value = "android.permission.EXECUTE_APP_FUNCTIONS", conditional = true)
public final boolean isAppFunctionEnabled(
    @NonNull String packageName,
    @NonNull String functionId
)

Checks if functionId in packageName is enabled.

This method matches the platform behavior defined in android.app.appfunctions.AppFunctionManager.isAppFunctionEnabled.

@RequiresPermission(value = "android.permission.EXECUTE_APP_FUNCTIONS", conditional = true)
public final @NonNull Flow<@NonNull List<@NonNull AppFunctionMetadata>> observeAppFunctions(@NonNull AppFunctionSearchSpec searchSpec)

Observes for available app functions metadata based on the provided filters.

Allows discovering app functions that match the given searchSpec criteria and continuously emits updates when relevant metadata changes. The calling app can only observe metadata for functions in packages that it is allowed to query via android.content.pm.PackageManager.canPackageQuery. If a package is not queryable by the calling app, its functions' metadata will not be visible.

Updates to AppFunctionMetadata can occur when the app defining the function is updated or when a function's enabled state changes.

If multiple updates happen within a short duration, only the latest update might be emitted.

@RequiresPermission(value = "android.permission.EXECUTE_APP_FUNCTIONS", conditional = true)
public final void setAppFunctionEnabled(@NonNull String functionId, int newEnabledState)

Sets newEnabledState to an app function functionId owned by the calling package.

This method matches the platform behavior defined in android.app.appfunctions.AppFunctionManager.setAppFunctionEnabled.
