Your code snippet is useful, but since it is a part of a larger project, some of my comments may be completely wrong. So, your patience is requested. 1. Do I understand your flow correctly -- you are sending an HTTP POST after *every keystroke*? After all, onKeyUp() will get called after every key event handled by this View. That is absolutely going to be slow. 2. Similarly, it would appear you are forking a thread after every keystroke, which seems aggressive. How about a single background thread, using a LinkedBlockingQueue or something for communications? When an event occurs in the UI thread that the background thread should process, the UI thread posts an event on the queue. The background thread blocks on the queue and handles events as they arise. 3. Even if you feel that having one background thread per keystroke is valid, I am not sure you want to join with the background thread. That ties up the UI thread until the background thread is done, which is not what you want. -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 2.0 Available! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
