Compiled APK Not Installing as Update

[PEB]

When I compile my applet, everything seems to go well. When I try to install it on my Android device, I'm asked if I want to update the app, I select "Update" and then I get this message:

App not installed as package appears to be invalid.

If I uninstall the previous installation, then I am able to install the newly compiled APK; however, when I open the app, an empty display appears, but the script doesn't seem even to start.

The applet works fine with the newest Hollywood Player for Android, so I don't think there is a problem between my script and Hollywood 11.

Is there a way to collect debug output from an app that crashes immediately?

Has anyone else had problems installing a newly compiled APK over a previous installation?

Yes, LogCat should give you more info on the crash.
