OneSignal postNotification Android

Question

I need postNotification in my native app android.

I have this code but it doesn't work:

try {
    OneSignal.postNotification(new JSONObject("{'contents': {'en':'Test Message'}, 'include_player_ids': ['" + userId + "']}"), null);
} catch (JSONException e) {
     e.printStackTrace();
}

Answer 1

Can you make sure the value in userId is a valid OneSignal id on your account and it is subscribed?

You can also use the following code instead to add logcat logging to debug the issue.

try {
  OneSignal.postNotification(new JSONObject("{'contents': {'en':'Test Message'}, 'include_player_ids': ['" + "userId" + "']}"),
     new OneSignal.PostNotificationResponseHandler() {
       @Override
       public void onSuccess(JSONObject response) {
         Log.i("OneSignalExample", "postNotification Success: " + response.toString());
       }
       @Override
       public void onFailure(JSONObject response) {
         Log.e("OneSignalExample", "postNotification Failure: " + response.toString());
       }
     });
} catch (JSONException e) {
  e.printStackTrace();
}
