Why we use handlers with thread :

When we install an application in android then it create a thread for that application called MAIN UI Thread, All activities run inside that thread , By the android single thread model rule we can not access UI elements (bitmap , textview etc..) directly for another thread defined inside that activity.

So if want to access Main UI Thread elements by another thread then we will use handlers.
