Xamarin: Issue when TargetSdkVersion set to API 31 in manifest - xamarin.android

Question

By refer to Xamarin.Android 12.0 Release Notes, I set TargetFramework to Android 12 and I able to deploy project without any problem.
However, I encountered following error when I set android:targetSdkVersion to API 31 in android manifest.
ADB0010: Mono.AndroidTools.InstallFailedException: Unexpected install output: Failure [INSTALL_PARSE_FAILED_MANIFEST_MALFORMED: Failed parse during installPackageLI: /data/app/vmdl204773411.tmp/base.apk (at Binary XML file line #84): com.urbanairship.accengage.PackageUpdatedReceiver: Targeting S+ (version 31 and above) requires that an explicit value for android:exported be defined when intent filters are present]
This happens only when android:targetSdkVersion set to 31 and deployed to physical device/emulator with android 12. I already added android:exported="true" to MainActivity class and classes that use intent filters. Could anyone advice me how to resolve this?

Answer 1

According to the error message, the PackageUpdatedReceiver in your project doesn't set a value for the android:exported. So you can try to set a value by the two following ways.
Set it in the attribute of the BroadCastReceiver:
[BroadcastReceiver(Exported = true)]
Set it into the application label in the AndroidManifest.xml:
Edit: For android 12, all the Services, BroadCastReceivers, Activity classes need to declare the value for the android:exported. So update the three part sdk to the last version.
