Xamarin :: Android - Original attribute defined here

Issue

I have Xamarin Android Project with Target Framework v9.

Recently, I updated my Xamarin Forms to latest version. Then, I am getting below error.

I understand from the error message that I need to update 'Target Framework' from Android 9 to Android 10. I did it.

From that moment, whenever I build my android project in 'Release' mode, I get below error. Building project in 'Debug' mode is fine.

May you please help? I need to submit an update to my Android App. :-(

Solution

From the comment of "Lucas Zhang - MSFT":

Please enable the

Use incremental Android packaging system (Aapt2)

which is available under Project Properties. It will resolve the error you posted.
