Handler is part of the Android system's framework for managing threads. A Handler object receives messages and runs code to handle the messages. Normally, you create a Handler for a new thread, but you can also create a Handler that's connected to an existing thread. When you connect a Handler to your UI thread, the code that handles messages runs on the UI thread. This way results of background work can be moved to UI elements such as bitmaps.
