Android: how to have a localbroadcast reciever inside service

Question

I have service in which I want to have a localbroadcast receiver. I want to recieve a value from the activity to my services onCreate.

Note: I can get a value from an activity to my service in onStartCommand() using intent. But here I want a value from activity in onCreate of the service.

The following is my service file:

    public class MediaServiceSimha extends Service {

        private MediaPlayer player;
        String musicpath;
        private ResponseReceiver receiver;

        public MediaServiceSimha() {}

        @Override
        public IBinder onBind(Intent intent) {
            return null;
        }

        @Override
        public void onDestroy() {
            LocalBroadcastManager localBroadcastManager = LocalBroadcastManager.getInstance(this);
            localBroadcastManager.unregisterReceiver(receiver);
            super.onDestroy();
        }

        @Override
        public boolean onUnbind(Intent intent) {
            return super.onUnbind(intent);
        }

        @
        Override
        public int onStartCommand(Intent intent, int flags, int startId) {
            player.start();
            return super.onStartCommand(intent, flags, startId);
        }

        @Override
        public void onCreate() {
            super.onCreate();
            IntentFilter broadcastFilter = new IntentFilter("com.example.myintentserviceapp.intent_service.ALL_DONE");
            receiver = new ResponseReceiver();
            LocalBroadcastManager localBroadcastManager = LocalBroadcastManager.getInstance(this);
            localBroadcastManager.registerReceiver(receiver, broadcastFilter);
        }

        public class ResponseReceiver extends BroadcastReceiver {

            @Override
            public void onReceive(Context context, Intent intent) {
                musicpath = intent.getStringExtra("musicpath");
            }
        }
    }

The following is my activity file where I want to pass a value called musicpath

public class ServiceTest extends AppCompatActivity {
    Intent intent;

    public static final String TEXT_INPUT = "inText";
    //MediaServiceSimha mediaServiceSimha;



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        L.m("activity_oncreate_starting");
        setContentView(R.layout.activity_service_test);
        intent= new Intent(this,MediaServiceSimha.class);

        startService(intent);

        Intent broadcastIntent = new Intent();
        broadcastIntent.setAction("com.example.myintentserviceapp.intent_service.ALL_DONE");
        broadcastIntent.putExtra("musicpath", "/storage/emulated/0/Download/1.mp3");
        LocalBroadcastManager localBroadcastManager = LocalBroadcastManager.getInstance(this);
        localBroadcastManager.sendBroadcast(broadcastIntent)
    }


}

After running, it says musicpath value is null.

How to do it?

Answer 1

My goal was to pass a variable value directly to oncreate in the service class.

I tried LocalBroadcast's reciver and also onbindservices - onServiceConnected

Both of them i found that they will only get executed untill oncreate -> onbind/onstartcommand get executed in the services.

So only option left is onstartcommand()

So when we pass values using intent then they can be used immediately inside onstartcommand.
