Difference between UI Thread and Worker Thread in Android?

Question

I have read documents about Thread on Android, but I could not find differences between UI thread and Worker Thread. Can someone just give me more example about it?

Answer 1

The Ui thread is the thread that makes any changes required for the ui.

A worker thread is just another thread where you can do processing that you dont want to interupt any changes happening on the ui thread

If you are doing large amounts of processing on the ui thread while a change to the ui is happening the ui will freeze until what ever you have running complete.
