I'm getting an error:
Manifest merger failed : uses-sdk:minSdkVersion 9 cannot be smaller than version 14 declared in library [androidx.appcompat:appcompat:1.0.0]
Ok, so what androidx.appcompat:appcompat should I set in order app to support versions from API 9 to 30? I already set the oldest androidx.appcompat:appcompat available in Android Studio. I saw some tuts that tell me to go to Open Module Settings > Flavours but there are no such tab in the current version.
