Mobile application responsiveness can make or break user experience. It is dramatically apparent when an application hangs for fractions of a second. On mobile devices that traditionally have less memory than their desktop counter parts, it is important to write code in such a way that resource intensive operations do not impact the experience. This often means asynchronous programming. The Android platform has numerous ways of writing asynchronous code. This session will explore many of the paradigms for handling asynchronous code on Android, including async tasks, adapters, services, loaders, queues, and events. Pros and cons and appropriate situations for these approaches will be discussed. Developers attending this session will leave with the tools to load data asynchronously and provide the smoothest UI experience for users of their Android applications.
