What happen when my Activity is destroyed when I'm using IntentService with ResultReceiver

Use a BroadcastReceiver on your Activity and register/unregister it in onResume() and onPause() respectively. You can use an IntentFilter to listen for an Intent from your IntentService.

In your IntentService, create an Action value for the IntentFilter and send a broadcast with that Action when you want to update:

public static final String ACTION = "com.example.yourapp.action.ACTION_TAG";private void handleResult() {    if (BuildConfig.DEBUG) {        Log.v(TAG, "handleResult");    }    // Broadcast result    Intent intent = new Intent(ACTION);    intent.putExtra("your_extra", someValue);    LocalBroadcastManager.getInstance(this).sendBroadcast(intent);}

In your Activity:

private BroadcastReceiver mYourReceiver = new BroadcastReceiver() {        @Override        public void onReceive(Context context, Intent intent) {            if (BuildConfig.DEBUG) {                Log.v(TAG, "onReceive");            }            Bundle bundle = intent.getExtras();            if (bundle != null) {                // Update with content from bundle            }        }    };     @Override     public void onResume() {         super.onResume();         if (BuildConfig.DEBUG) {             Log.v(TAG, "onResume");         }         // Register broadcast receiver         LocalBroadcastManager.getInstance(getActivity()).registerReceiver(mYourReceiver, new IntentFilter(YourIntentService.ACTION));    }    @Override    public void onPause() {         super.onPause();         if (BuildConfig.DEBUG) {             Log.v(TAG, "onPause");         }         // Unregister broadcast receiver         LocalBroadcastManager.getInstance(getActivity()).unregisterReceiver(mYourReceiver);    }
