I'm uploading a new project and I'm getting this error:
Play installer check requires a minimum SDK version of 21 or higher. The uploaded App Bundle has a minimum SDK version of 7. Update the minSdkVersion in your app's Android manifest.
I've figured it out! Thank you! Now I'm getting an exciting NEW error:
"You uploaded an APK or Android App Bundle that is signed with a key that is also used to sign APKs that are delivered to users. Because you are enrolled in Play App Signing, you should sign your APK or Android App Bundle with a new key before you upload it."
