I am developing an Android application which use a native library and native library supports targetSDKVersion = 29 only. I created a new Android project has default targetSDKVersion =31, I tried to set targetSDKVersion as 29, but I got the error messsage as below image:
I have another Android project it has targetSDKVersion = 29 without error message, I don't know why I can't set targetSDKVersion = 29 for the first project.
How can I set targetSDKVersion as 29?
