performSelectorOnMainThread equivalent in Java for Android

Question

I have an iPhone application and I am porting it over to Android.

I have a service/controller that spawns new threads to perform some network tasks.

I use performSelectorOnMainThread in my iPhone app. How can I have my Java app do the same or similar thing?

Answer 1

Options:

1. manual threading + Handler or runOnUiThread(..) available from Activity for posting UI changes
2. AsyncTask
3. Service for lengthy background operations

Answer 2

Assuming performSelectorOnMainThread does what I think it does, look at runOnUiThread() in Activity, or post() on Handler or any of your Views (i.e., your GUI widgets).

Though I generally agree with alex's answer -- use AsyncTask where possible, rather than forking your own threads.
