Android Event Dispatch Thread or Main Thread – Tutorial

Android applications run in a native Linux process, in the underlying Linux OS. This process houses activities (screens), widgets, and services (non visual long running application parts). When working with Android apps, it is important to remember to keep long running code running in threads that are not tied to the main thread or event dispatch thread, in order to get an “application not responding” error. A common mistake that is made is long running tasks are performed in this EDT/main thread, and this leads to lots of application failures.

Android – How to build a service-enabled Android app – Part 3/3 Multithreading

I’ve written 3 tutorials to show you how to create a service enabled Android application that performs all of it’s network I/O in a background thread (not the UI thread). These tutorials are split into three parts. This tutorial shows you how to use background threads to perform long running network IO operations, so that the main UI thread is not locked up.
