Broadcast Receiver service feedback with activity not work

Question

i created a Broadcast Receiver for service feedback with activity. But this not work. Debugger -- after calling sendBroadcast from the service, skips this (LocalBroadcastManager.getInstance(this).sendBroadcast(RTReturn);) line and does not cause Activity

This is Activity
package com.example.my;

 BroadcastReceiver br;
public static final String RECEIVE_JSON = 
"com.example.my.RECEIVE_JSON";
 public class cama extends AppCompatActivity
@Override
protected void onCreate(Bundle savedInstanceState) {
    xcxc();
    xcx();
            }

    public void xcxc()
    {
     br = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        if(intent.getAction().equals(RECEIVE_JSON)) {
        String serviceJsonString = intent.getStringExtra("json");
                Toast toast = Toast.makeText(getApplicationContext(),
                        "Test!", Toast.LENGTH_SHORT);
                toast.show();
        }
         }
        };
   }
public void xcx()
{
    LocalBroadcastManager bManager;
    bManager = LocalBroadcastManager.getInstance(this);
    IntentFilter intentFilter = new IntentFilter();
    intentFilter.addAction(RECEIVE_JSON);
    bManager.registerReceiver(br, intentFilter);
}

      @Override
public void onDestroy() {
    super.onDestroy();
    if (br != null) {
    unregisterReceiver(br);
    }
       }

This is Service

package com.example.my;
public class MyService extends Service
      @Override
     public void onCreate() {
       do_anything();
         }
     public void do_anything()
     {Intent RTReturn = new Intent(cama.RECEIVE_JSON);
     RTReturn.putExtra("json", "ole");
     LocalBroadcastManager.getInstance(this).sendBroadcast(RTReturn);}

protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_cama); xcxc(); — Анатолий Солнцевский, Jun 18 '18 at 10:38
and also where you are starting service. Is your service staring successfully ?? — Iamat8, Jun 18 '18 at 10:50
I use LocalBroadcastManager, so I did not write anything in the manifest. In the service it starts, the debugger sees it if (camera == null) { Intent RTReturn = new Intent(cama.RECEIVE_JSON); RTReturn.putExtra("json", "ole"); LocalBroadcastManager.getInstance(this).sendBroadcast(RTReturn);} camera.unlock(); — Анатолий Солнцевский, Jun 18 '18 at 11:00
Dear are you staring the service.??? I have tried your code with global braodcast send system.. It is working fine !! — Iamat8, Jun 18 '18 at 11:04
And one more thing, you are registering broadcast to `LocalBroadcastManager` and unregistering to Activity — Iamat8, Jun 18 '18 at 11:24
Yes, i start service with camera and debugger stops at "sendBroadcast(RTReturn);" Then force step into with debugger-after 2 step initialization debugger exit without nulls and errors. I did everything as https://stackoverflow.com/questions/8802157/how-to-use-localbroadcastmanager , but nothing changed. — Анатолий Солнцевский, Jun 18 '18 at 12:20
How do you "start service with camera". What does that mean? — David Wasser, Jun 18 '18 at 13:08
@АнатолийСолнцевский Have you tries my solution ? — Iamat8, Jun 19 '18 at 09:22

just use inside onCreate(Bundle savedInstanceState):

LocalBroadcastManage 
mlocal = LocalBroadcastManager.getInstance(getApplicationContext());

mlocal.sendBroadcast(YOUR Reciever)
