A few pointers on how to make a splash screen.
I think you SplashScreen is only shown when the App is starting. So if the Acitivites aren't finished but just paused the SplashScreen will not be shown because the App wasn't really closed. You can either finish the application when back button is pressed (Code: this.finish()) or check on every Activity's onResume()-Method if the App was in Background and show the SplashScreen if true.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
