Chapter 2. Staying Responsive with AsyncTask
The first Android-specific concurrency construct we'll look at is android.os.AsyncTask, a neat construct that encapsulates the messy business of managing threads, performing background work, and publishing progress and results back to the main thread to update the user interface.
In this chapter we will cover the following topics:
- Introducing
AsyncTask - Declaring
AsyncTasktypes - Executing AsyncTasks
- Providing feedback to the user
- Providing progress updates
- Canceling AsyncTasks
- Handling exceptions
- Controlling the level of concurrency
- Common
AsyncTaskissues - Applications of
AsyncTask
