So I have a client that has sent me a keystore file and told me that is how I will get the APK. I followed the directions for generating an APK from a keystore here: https://developer.android.com/studio/publish/app-signing#sign_release
What am I missing here? Why am I still loading the default blank project I am trying to load? Have I overwritten something?
i think you miss understood the concept of a keystore . the keystore is used along with a password to sign an apk or aab of an existing project. so if a client sent you a keystore how do you expect to get an apk from the keystore file ? it doesn't contain an apk in it .
