Re-launching android application when user clicks Urban Airship notification

I have an android app successfully set up to receive notifications using Urban Airship, but am running into problems in handling the PushManager.ACTION_NOTIFICATION_OPENED) broadcast. My BroadcastReceiver is working, receiving the message, and calling the following (from the example code):

Intent launch = new Intent(Intent.ACTION_MAIN);
launch.setClass(UAirship.shared().getApplicationContext(), Main.class);
launch.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
UAirship.shared().getApplicationContext().startActivity(launch);

This works fine and brings the main activity back to the foreground, except for the case in which the app is no longer running. If I send a notification to a phone, kill the app, and then open the notification, the app crashes on a NullPointerException:

Failed to load meta-data, NullPointer: null
Unable to takeOff automatically
FATAL EXCEPTION: main
java.lang.RuntimeException: Unable to start receiver com.urbanairship.CoreReceiver:         java.lang.NullPointerException

at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553)
at dalvik.system.NativeStart.main(Native Method)

I can't figure out what could be causing this. Any thoughts?

I met the same problem. I resolved it by putting the UAirship initialization into the onCreate of Application, not activity.

Hi Amit Jayaswal, please see the follow example:

public class MyApplication extends Application {

@Override
public void onCreate() {
    super.onCreate();

    // Optionally, customize your config at runtime:
    //
    // AirshipConfigOptions options = new AirshipConfigOptions();
    // options.inProduction = false;
    // options.developmentAppKey = "Your Development App Key";
    // options.developmentAppSecret "Your Development App Secret";
    //
    // UAirship.takeOff(this, options);

    UAirship.takeOff(this, new UAirship.OnReadyCallback() {
        @Override
        public void onAirshipReady(UAirship airship) {
            // Perform any airship configurations here

            // Create a customized default notification factory
            DefaultNotificationFactory defaultNotificationFactory = new DefaultNotificationFactory(getApplicationContext());
            defaultNotificationFactory.setSmallIconId(R.drawable.ic_notification);
            //defaultNotificationFactory.setColor(NotificationCompat.COLOR_DEFAULT);

            // Set it
            airship.getPushManager().setNotificationFactory(defaultNotificationFactory);

            // Enable Push
            airship.getPushManager().setPushEnabled(true);
        }
    });
}

}

OK, figured it out.

I was instantiating the UrbanAirship and registering the IntentReceiver from an Activity context, not from an Application context.

Oops.
