                i1.putExtra("Latitude", loc.getLatitude());
                i1.putExtra("Longitude", loc.getLongitude());

            }
        });
    }
}

and on activity I have write

  @Override

        protected void onResume() {
            registerReceiver(broadcastReceiver, new IntentFilter(LocationReceiver.BROADCAST_ACTION));
}

    private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                UpdateUI(intent);
            }
        };

        private void UpdateUI(Intent i){
            Double Latitude = i.getDoubleExtra("Latitude",0); 
            Double Longitude = i.getDoubleExtra("Longitude",0);
            showMap(Latitude, Longitude);
        }

Now my problem is when it sendbroadcast it execute infinitly doBroadcast function(), please help me to come out.

Please refer SDK document

receiverPermission is (optional) String naming a permissions that a receiver must hold in order to receive your broadcast. If null, no permission is required.

AndroidManifest.xml use. this is on String. the String use sendOrderedBroadcast's receiverPermission. value.
