When i run my script below everything works fine. When i want to go back to the previous activity i get a black screen on the emulator and then the app shuts down, i also get a black screen when i exit the application and try to resume it.
The script:
}
I dont get any error message in the log, what i do get is about 13 messages saying "suspending all threads took: X ms" so it has something to the with my gameloop Thread i think. Unfortunately i dont see what the problem is in my code... Can anyone help me with this?
