Handler vs Thread

Question

I would like to know, once for all. I\'ve read in many places. When I want do some \'long time operations\' I should use a Handler.

But I don\'t get why? A

Answer 1

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.
