- The Handler class can be used to register to a thread and provides a simple channel to send data to this thread. A Handler allows you communicate back with the UI thread from other background thread.
- The AsyncTask class encapsulates the creation of a background process and the synchronization with the main thread. It also supports reporting progress of the running tasks.
- And a Thread is basically the core element of multithreading which a developer can use with the following disadvantage:
- Handle synchronization with the main thread if you post back results to the user interface
- No default for canceling the thread
- No default thread pooling
- No default for handling configuration changes in Android
