what should I use to access network asynchronously in android?

Question

I implemented an AsyncTask in my app and encountered exceptions like IllegalArgumentException. I asked question on stack overflow somebody said I shouldn't use AsyncTask in apps for the following reasons.

AsyncTasks don't follow Activity instances' life cycle
Memory leak issue
Progress of your task will be lost

I was recommended Robospice and also told consider this thread AsyncTask is not really the best tool to create network requests on Android. use RoboSpace

Can anybody tell me what is best option to use access network asynchronously? What should I use AsyncTask or RoboSpice?

who said not to use AsyncTask? It is perfectly fine to use for anything that may take longer to execute. — waqaslam, Apr 16 '13 at 09:52
You can also use a executor http://developer.android.com/reference/java/util/concurrent/Executor.html — Raghunandan, Apr 16 '13 at 09:53

According to this guy at Google IO, using AsyncTask for networking is not the way to go. He may give his presentation with an annoying & condescending tone, but nonetheless has some good points.

IMO the leading libraries to use are android-async-http and robospice.

DISCLAIMER: I haven't tried either of these yet. While I like the API of android-async-http better, it seems like Robospice was more recently developed and supports better libraries.

I may end up rolling my own that extends IntentService.

thanks steve for your information. actually I know about robospice but don't know how to use it. – Nilesh May 02 '13 at 08:06
@Nilesh yeah I think it seems a bit heavy and confusing to get started with. I may publish my `IntentService` + `ResultReceiver` if I think it's worth sharing. Stay tuned. ;) – steve May 03 '13 at 22:50

here is an Android Asynchronous Http Client library file to do these work. Have a try.

I have been using AsyncTasks for a few projects and never had that problems. Nevertheless as Snicolas said in that post, is possible to had problems if you use AsyncTasks for long running operations (note the bold).

So if you're doing short ops, try AsyncTasks, otherwise I would give Robospice a try.

an asyncTask instance just can use one time,if you want to execute the second request must call new () again
