Hi, I'm working on a Froyo firmware for a multimedia set top box as a hobby project. I want to use the android-support-v4 library in several platform apps, so I decided to backport it to froyo and include it as a framework java library. The platform apps can then define the dependency with the uses-library manifest tag. This kind of works, but I'm facing a strange behavior: When I build the firmware and include the apps, they don't work and force close with a message like this:
W/dalvikvm( 723): Unable to resolve superclass of > Lcom/example/launcher/HomeActivity; (18) > W/dalvikvm( 723): Link of class 'Lcom/example/launcher/HomeActivity;' > failed HomeActivity inherits from FragmentActivity, which is part of the support library. So I suppose, that the support library is not in the classpath of the app. Now the surprise: If I delete the app with "rm" and "pm uninstall", then reboot the box and afterwards install the same apk by adb pushing it to /system/app (where it has been before deleting it), everything works fine. Any ideas, what could cause this strange behavior?
