Threads : Android

Threads : Android
Even though you may confine your application to a single process, there will likely be times when you will need to spawn a thread to do some background work. Since the user interface must always be quick to respond to user actions, the thread that hosts an activity should not also host time-consuming operations like network downloads. Anything that may not be completed quickly should be assigned to a different thread.

Threads are created in code using standard Java Thread objects. Android provides a number of convenience classes for managing threads — Looper for running a message loop within a thread, Handler for processing messages, and HandlerThread for setting up a thread with a message loop.
