Along with this Raghav's advice, Android has a good amount of support for Threading utilities that take care of some of the dirty stuff for you, it's a nice alternative that meshes well with the framework (contrast to a "Thread" object). You can check out AsyncTask, which might do what you want in this case, and makes threading a little less painful..
