Google Play is rejecting an AAB because it targets API level 30

[LorenDB]

I'm trying to upload an app to the Google Play Console, but every time I upload the .aab, I get this error:

Your app currently targets API level 30 and must target at least API level 31 to ensure it is built on the latest APIs optimized for security and performance. Change your app's target API level to at least 31.

This seems odd. I've tried:

• Removing all SDKs below SDK 31 from my system
• Adding set(QT_ANDROID_MIN_SDK_VERSION 31) to my CMakeLists.txt

and maybe a few other random things here and there.

Does anybody have insight on this? I'm building with Qt 6.4.2. I've also had this problem building for multiple Android architectures.

I fixed this by doing two things:

1. Changing set(QT_ANDROID_MIN_SDK_VERSION 31) to set_target_properties(appHeartless PROPERTIES ... QT_ANDROID_TARGET_SDK_VERSION 31)
2. Adding android:export="true" to the <activity> tag in my Android app manifest.
