Handler vs Thread

Question

Hi, I would like to know, once for all.. ive read in many places.. when i wanna do some 'long time operations' i should use a Handler.

But i dont get why? all my 'long-time-operations' i surround with a regular threads, and it works fine.

why would I use handler for this?

the only time i had to use Handler was, when I had to scheduale some task(postDelayed)

Is there any main idea i miss about handlers(When i should realy use it)? or mybe there isnt realy diffrence?

realy thanks,

ray.

A Handler lets you communicate back with the UI thread from your background thread. This is because UI operations are forbidden from within background threads. Note that starting at version 1.5, the AsyncTask class makes it much easier to do so.
