I have the same problem but I can solve it temporarily doing a clean restart:
using Windows XP that is: 1. Closing Eclipse. 2. Clearing the folder C:\Documents and Settings\username\Local Settings\Application Data\Android 3. Starting Eclipse and running my App. (Clearing using just wipe-data does not seem to work) It will now work great and I get the expected behavior where the app goes back to activity that you had when you pressed Home. But as soon a I re-run the app in Eclipse (even without code changes) it will always go back to the main launch activity after pressing Home. I won't get the expected behavior again until I do another clean restart. I have no unusual settings in my AndroidManifest.xml and because it fully works after a restart I assume it is an Eclipse/Emulator thing. Sometimes after the re-run I also get this message in the console: [2008-08-25 15:02:09 - myApp] Re-installation failed due to different application signatures. [2008-08-25 15:02:09 - myApp] You must perform a full uninstall of the application. WARNING: This will remove the application data! [2008-08-25 15:02:09 - myApp] Please execute 'adb uninstall com.mycompany.myApp' in a shell.
