Trying to migrate from Parse to OneSignal and I am stuck on how to start a new Activity after the user clicks on a push notification. My handler is working, the log shows th

Here's how I made it work:

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        OneSignal.startInit(this)
                .setNotificationOpenedHandler(new MyNotificationOpenedHandler(this))
                .init();
    }
}

The NotificationOpenedHandler custom class

public class MyNotificationOpenedHandler implements OneSignal.NotificationOpenedHandler {

    private Application application;

    public MyNotificationOpenedHandler(Application application) {
        this.application = application;
    }

    @Override
    public void notificationOpened(OSNotificationOpenResult result) {

        // Get custom datas from notification
        JSONObject data = result.notification.payload.additionalData;
        if (data != null) {
            String myCustomData = data.optString("key", null);
        }

        // React to button pressed
        OSNotificationAction.ActionType actionType = result.action.type;
        if (actionType == OSNotificationAction.ActionType.ActionTaken)
            Log.i("OneSignalExample", "Button pressed with id: " + result.action.actionID);

        // Launch new activity using Application object
        startApp();
    }

    private void startApp() {
        Intent intent = new Intent(application, MyActivity.class)
                .setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_NEW_TASK);
        application.startActivity(intent);
    }
}

Don't forget to add this to your manifest:

<application ...>
   <meta-data android:name="com.onesignal.NotificationOpened.DEFAULT" android:value="DISABLE" />
</application>

The short answer to this issue is to include your handler for the push notification open within the same class where you initialize OneSignal:

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Init OneSignal
        OneSignal.startInit(this).setNotificationOpenedHandler(new NotificationOpenHandler()).init();

        Toolbar mToolbar = (Toolbar) findViewById(R.id.app_bar);
        setSupportActionBar(mToolbar);
        getSupportActionBar().setDisplayUseLogoEnabled(true);
        getSupportActionBar().setLogo(R.drawable.ic_launcher);
        getSupportActionBar().setDisplayShowTitleEnabled(false);
        if (savedInstanceState == null) {
            getFragmentManager().beginTransaction()
                    .add(R.id.container, new RecordingsFragment())
                    .commit();
        }
    }

    class NotificationOpenHandler implements OneSignal.NotificationOpenedHandler {
        // This fires when a notification is opened by tapping on it.
        @Override
        public void notificationOpened(OSNotificationOpenResult result) {
            OSNotificationAction.ActionType actionType = result.action.type;
            JSONObject data = result.notification.payload.additionalData;

            String stationName = data.optString("stationName");
            String timestamp = data.optString("timestamp");
            String filename = data.optString("filename");
            String url = getString(R.string.callResourceUrl) + filename;

            Intent intent = new Intent(getApplicationContext(), CallActivity.class);
            intent.putExtra("stationName", stationName);
            intent.putExtra("time", timestamp);
            intent.putExtra("url", url);
//            intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(intent);
        }
    }
}
