Tapping a Notification from OneSignal does not ope

Question

Now I know there are lot of questions on this, but I have faced no luck at all and thought to ask a question here.

I have an application which just runs a splashscreen followed by a MainActivity(Which is just a WebView) Now I integrated this with OneSignal for receiving push notifications.

Everything works good, I mean I get a notification when sent through the onesignal website to my phone - but the thing I am facing is, tapping the notification does not get my ResultActivity(Just a activity displaying a Toast of message).

My code snippets looks as below:

splashscreen.java:

public class splashscreen extends Activity {
@Override
   public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.splash);
      Thread splashThread = new Thread() {
         @Override
         public void run() {
            try {
               int waited = 0;
               while (waited < 5000) {
                  sleep(100);
                  waited += 100;
               }
            } catch (InterruptedException e) {
               // do nothing
            } finally {
               finish();
               Intent i = new Intent();
               i.setClassName("com.google",
                              "com.google.Main");
               startActivity(i);
            }
         }
      };
      splashThread.start();
   }
   @Override
   protected void onPause() {
       super.onPause();
       OneSignal.onPaused();
   }
   @Override
   protected void onResume() {
       super.onResume();
       OneSignal.onResumed();
   }
} 

Main.java:

@SuppressLint("SetJavaScriptEnabled") public class Main extends Activity     {
    /** Called when the activity is first created. */

    WebView web;
    private static Activity currentActivity;

    Intent resultIntent = new Intent(this, ResultActivity.class);


    @Override

        super.onCreate(savedInstanceState);

        currentActivity = this;

        web = (WebView) findViewById(R.id.my_webview);

I have tried all these answers but none worked:

Notification Not open Acivity onCLick

Android Status Bar Notifications - Opening the correct activity when selecting a notification

Android :Tap on Push Notification does not open Application

Android click on notification does not open the attached Activity

It is painfull to modify one line and test it on device! Since onesignal allows only testing in device. Please help or atleast guide me how to debug.

Device on which the apk was tested : Samsung Galaxy S4 running Lolipop.

Take a look at this link: https://documentation.onesignal.com/docs/android-customizations#section-background-data-and-notification-overriding (Search : "Changing the open action of a notification" in the page to go to the exact paragraph).

And this is an example: http://androidbash.com/android-push-notification-service-using-onesignal/

I don't have time to read your code carefully, but seems like it has some problems:

1. You initialize OneSignal in the wrong place.

   "Make sure you are initializing OneSignal with setNotificationOpenedHandler in the onCreate method in your Application class. You will need to call startActivity from this callback" (OneSignal's document).

2. You don't need any other receivers in AndroidManifest to catch intent and open your target activity, OneSignal.NotificationOpenedHandler already handle this. But don't forget this line to prevent OneSignal open your launcher activity:

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

I use this solution in my app and it works fine. Because it's the way it is.

Answer 2

OneSignal.init must be called from your launcher Activity, you will need to move it to your splashscreen Activity. This will get your ExampleNotificationOpenedHandler to fire when you open a OneSignal notification.

Make sure to also copy the calls to OneSignal.onPaused(); and OneSignal.onResumed(); into your splashscreen Activity. These need to be called in every Activity in the onPuase() and onResume() methods.
