public abstract class ContentProviderWithCallbacks<T extends ContentProviderWithCallbacks> extends ContentProvider implements CallbackReceiver

java.lang.Object
↳	android.content.ContentProvider
	↳	androidx.remotecallback.ContentProviderWithCallbacks

Version of ContentProvider that can be used as a CallbackReceiver. Be sure to call the super of call when unhandled to ensure callbacks are triggered.

Parameters
`<T extends ContentProviderWithCallbacks>`	Should be specified as the root class (e.g. class X extends ContentProviderWithCallbacks\)

createRemoteCallback

Added in 1.0.0-alpha02

public T createRemoteCallback(Context context)

Creates a RemoteCallback that will call the method with method specified with the arguments specified when triggered. Only methods tagged with RemoteCallable can be used here. This method returns a stub implementation of the class calling it to record the arguments/method being used. This should only be used in a chain of 2 calls, starting with createRemoteCallback(), then followed up with a call to any method tagged with RemoteCallable.

    createRemoteCallback().callMyMethod("My arguments", 43, 2.4)
             .toPendingIntent(context);

    \@RemoteCallable
    public RemoteCallback callMyMethod(String argStr, int argInt, double argDouble) {
        ...
        return RemoteCallback.LOCAL;
    }
