Which sample project you are trying to compile?

Simplest solution is to delete the Android SDK and download a new one. Another option is to rollback the problematic versions: https://www.b4x.com/android/forum/t...4-has-already-been-defined.127396/post-799369

After downloading
Error: Error: Could not find or load main class com.android.sdklib.tool.sdkmanager.SdkManagerCli

I've had that error but couldn't see why. It seemed to automagically cure itself in my case. You could try downloading the SDK (yet) again!
