This is a cool game for Android where you have to destroy all enemy spaceships that attack you. Dodge their attacks or you lose some life. There's also checkpoints you can get to destroy your enemies easily or to restore some life that you lost on battle. At beginning it starts really slow but then you gonna have a bad time to destroy them all.
My app contains Activity. I start it by Intent. Than I turn my Activity to background (switch to Home Screen or similar). After some time the OS destroy my Activity (I think when memory is low). It is possible protect my Activity (in background) from destroy by OS? Or increase it priority to maximum?
