add this into your delegate or activity on onCreate

ParsePush.subscribeInBackground("[channel name]", new SaveCallback() {
          @Override
          public void done(ParseException e) {
            if (e == null) {
              Log.d("com.parse.push", "successfully subscribed to the broadcast channel.");
            } else {
              Log.e("com.parse.push", "failed to subscribe for push", e);
            }
          }
        });
