createRemoteCallback

public @NonNull T createRemoteCallback(@NonNull 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;
    }
