Resolving Splash Screen Issue in Mobile App

I am creating an Android mobile app from a book. When in Publish Settings > Application Details, when I try to change the Splash Screen image it reverts to the Icon image.

I locate the Icon image and then the splash screen image. After selecting the Splash screen image the image that displays in the dialog box is the Icon image.

After generating the apk the Icon is OK but the Splash screen briefly displays a white screen.

I have tried to follow instruction in the Help but it still reverts back when I edit Settings.
