Android build is target, ‘google android project’ is set, player settings/key-keystore info is set, passwords chosen, but on build, only folders and files are output, no apk. PLEASE ADVISE!
If you want an APK, try not selecting “Google Android project”
See here, that feature is useful in case you want to continue working on the project after Unity builds it. If you want an APK, Unity can just give you that, instead.
