    Intent notificationReceived = new Intent("com.example.mypackage”);
    notificationReceived.putExtra(“key", fromWhere);
    sendBroadcast(notificationReceived);
    }
    }

    android:name="com.example.pushnotification.GCMListener_Service"
    android:exported="false">

look at https://stackoverflow.com/questions/46015332/receiver-stopped-receiving-in-oreo — Ashvin solanki, Sep 24 '18 at 05:57
you now need to register your receiver in application class and also call it using the application class. Do not register your broadcast in your manifest file anymore. :) — Umair, Sep 24 '18 at 06:01
@Ashvinsolanki i dont have Context in GCMListener_Service class — Anil Thakur, Sep 24 '18 at 06:05
@AnilThakur I have posted an example code as an answer please check if it helps you get what you are trying to do. This broadcast is about checking internet connectivity you can modify it according to your requirements. — Umair, Sep 24 '18 at 06:09

In your Application class register and unRegister class like this:

    public class YourProjectApplication extends MultiDexApplication {
   private static YourProjectApplication sInstance;



    public static YourProjectApplication getInstance() {
            return sInstance;

        }

     @Override
    public void onCreate() {
        super.onCreate();
        sInstance = this;
        }

         public void registerInternetConnectivityBroadCast(){
                IntentFilter intentFilter = new IntentFilter();
                intentFilter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
                registerReceiver(appInternetStatus, intentFilter);

        }

        public void unSetConnectivityListener(AppInternetStatus.InternetConnectivityReceiverListener listener) {
            try {
                unregisterReceiver(appInternetStatus);
            }catch (Exception e){
              e.printStackTrace();
            }

            try {
                AppInternetStatus.internetConnectivityReceiverListener = listener;
            }catch (Exception e){
               e.printStackTrace();
            }
        }

And then in your mainActivity class (which can also be your base class) call your broadcast receiver like this:

 getInstance().registerBroadCast();
 getInstance().setConnectivityListener(this);

And in order to unregister your notification. In your onPause() method of your main activity class :

@Override
protected void onPause() {
    super.onPause(); 
    getInstance().unSetConnectivityListener(null);
}

no coz i dont know how to register GCMListener_Service register and unregister in Application Class — Anil Thakur, Sep 24 '18 at 07:55
