I've actually been looking for a solution to this quandary for some time. The quickest is just to add this property to each activity tag in your AndroidManifest.xml file:
*android*:configChanges="keyboardHidden|*orientation*" However, this won't keep your task/download working if, say, the user takes a call or presses the home key. However, although the official documentation advises against using this method, it is actually used in the messaging application. Anyways, you probably want a more robust method. To do this, you can either: 1. Create a service and work with downloads in there, and communicate with your UI activity if it exists. This approach is better if you have some sort of download manager or feed updater that must work in the background 2. Work in AsyncTask, which is better for shorter tasks (if you want to quickly fetch a file, parse it, and update the user interface). There are a few techniques here. You can pass references to your task when the activity is destroyed between orientation changes with onRetainNonConfigurationInstance(). Or, you can hold the reference to your task by holding it in the Application object, accessible to all activities. Have a look at http://www.fattybeagle.com/2011/02/15/android-asynctasks-during-a-screen-rotation-part-ii/ for code (and read Part I where the author goes over the other possibilities) Hope this helps! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
