Hi rjoshua,
mal wieder vielen Dank! Thank you very much for your help!
your both apps are running fine on my phone.
So i uninstalled alls - really alls and installed alls new - same problem...
Now, i created a new (third) debug.keystore, but now with a different keystore user like the default...
and,
YEAH!!! IT WORKS!!!
i tested my very small testapp...it works fine :)
i added a touchscreenbutton and a small animation...and...
IT WORKS!!!
Yes, this made my day!
Thank you alls for your help - my probleme here looks like solved :)
Have a nice day, i will :)
Happy coding!
