Passing onActivityResult in Cordova

Question

Does Cordova have any automatic way to pass onActivityResult to its CordovaPlugin classes?

Here's my current file, doing it manually:

package com.myapp;

import android.os.Bundle;
import org.apache.cordova.*;

import android.content.Intent;

import com.flyingsoftgames.googleplaytoken.GooglePlayToken;

public class MyApp extends CordovaActivity {

 @Override protected void onActivityResult (int requestCode, int resultCode, Intent data) {
  GooglePlayToken.runOnActivityResult (requestCode, resultCode, data);
 }

 @Override public void onCreate (Bundle savedInstanceState) {
  super.onCreate (savedInstanceState);
  super.init ();
  super.loadUrl(Config.getStartUrl());
 }
}

I tried to use the same technique employed in https://github.com/apache/cordova-plugin-camera/blob/master/src/android/CameraLauncher.java to get the data passed through "automatically" -- but it crashes. Here is a working (manual and no data pass-through) and non-working (automatic data pass-through) version of the target class. First working, then non-working.

Working, no data pass-through:

Answer 1

Turns out that all I needed to do was to run cordova.setActivityResultCallback (this); before cordova.getActivity().startActivityForResult (intent, REQUEST_CODE_PICK_ACCOUNT);.
