Thanks for your answer.
I didn’t get this error anymore, but got 100 more.
android-24 works.
But android-25 not.
Do I need to download SDK version of android studio?
EDIT: OK, I just see, everything that is under android-28 is created with android-30. That’s why the android-24 worked. But with android 30 has been built. Therefore I only see the UE4 logo on Android and it does not start.
How can I get Android 25 or 24? Which unrealengine version do I need?
