My android project is building fine in 4.15 but, the apk starts and then crashes when I run it on the phone. As you, It was running fine in 4.14
Anyway, for your problem, I’ll tell you what I try.
Try to create a blank project, go for 3D/2D for insert reason here, save the default map and set it in maps and mode. Don’t change any settings.
Go to the android under Project settings → Platforms → Android and configure it (not the play servicces). Check Package game data inside apk.
Project settings → Project → Supported Platforms → Check only Android
Packaging → Create compressed if you like. And try to package (I do it for ETC1)
Also, just for note. I have → Full package.
If it still don’t work. Go to the launcher. Click that little arrow near the launch button (In the “engine version” section) and select verify.
If still not working then the only solution I can suggest is re-download and re-install.
