How to call Web-Service (HTTP Request) when app is killed by swiping in android?

When I kill application by swiping from recent application list at that time I want to call Web-Service (or AsyncTask ).

What I used?

I am trying to call AsyncTask on destroy of activity.

AsyncTask contains WebApi request (using DefaultHttpClient ).

Code like this...

@Override
protected void onDestroy() {
    String url = "<webapi-url here>";
    new GetResponse().execute(url);
    super.onDestroy();
}

I am not using any background service.

Used only Activities, not containing any Fragment.

If any solution then please share here.

Answer 1

You can write an Android service component which overrides a method called onTaskRemoved() which will be triggered whenever app is removed by swiping from recents. So you can try this solution and see it fulfills your requirement.

Answer 2

No, there's no reliable way to know if your application was killed by a another process. The whole point of "killing" an app is to terminate it as soon as possible, without letting it run any code.

You have a similar post, the next time search a little please, but you can see this posts: AsyncTask will always run even if app is destroyed? or Async task stopped when App terminates (onDestroyed is called) .

In summary the AsyncTask works when app is destroyed but the app can crash if you try to modify UI. Tell me if I helps you, good programming!
