Android Async, Handler or Timer?

Question

Every 5 seconds, I want to call my webservice and get text (not images), then display it in my ImageAdapter. What would be the best way to accomplish this?

Answer 1

final Handler handler = new Handler(); 
    final Runnable r = new Runnable()
    {
        public void run() 
        {
            callWebservice();
        }
    };

    handler.postDelayed(r, 5000);
