Running code in main thread from another thread

Question

In an android service I have created thread(s) for doing some background task.

I have a situation where a thread needs to post certain task on main thread\'s message

There is another simple way, if you don't have an access to the Context.

1). Create a handler from the main looper:

Handler uiHandler = new Handler(Looper.getMainLooper());

2). Implement a Runnable interface:

Runnable runnable = new Runnable() { // your code here }

3). Post your Runnable to the uiHandler:

uiHandler.post(runnable);

That's all ;-) Have fun with threads, but don't forget to synchronize them.
