Your source works without problems, but when I copied the codes into an empty project for testing, I encountered the same error as I posted in post #5. I am attaching the source, please see where the problem is!
Also in your source I changed the color to #ffffff in the manifest but the Android 12 mandatory splash background is still blue. Another problem is that the splash screen icon is round, how can I make it rectangular and how can I change its size?
I know your project is based on B4xPages request, but I want to use this to update one of my old projects.
