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 I already added android:exported="true" to MainActivity class and classes that use intent filters. Could anyone advice me how to resolve this?

Based on this error, you should add android:exported to PackageUpdatedReceiver not add it to MainActivity. If PackageUpdatedReceiver is a broadcast receiver, you can add android:exported property like following code.
[BroadcastReceiver(Enabled = true, Exported = true)]
public class PackageUpdatedReceiver : BroadcastReceiver
{
public override void OnReceive(Context context, Intent intent)
{
Toast.MakeText(context, "Received intent!", ToastLength.Short).Show();
}
}
I donot know if you used statically-registered broadcast receiver or include intent-filters. You can refer this thread about setting true or false for Exported
For a statically-registered broadcast receiver, the Enabled properly must be set to true, otherwise Android will not be able to create an instance of the receiver.
For dynamic-registered broadcast receiver. The Exported property controls whether the broadcast receiver can receive messages from outside the application. If there is at least one intent-filter for the broadcast receiver the Exported property is true. If there are no intent-filters associated with the broadcast receiver, this value could be false.
Basically we use only intent-filters and no BroadcastReceiver in our project. And, we already added android:exported="true" to the classes.
It's strange that this issue happened only in physical devices/emulator with android 12
Can you share a demo that could reproduce this issue?
I couldn't create any demo at the moment because I cannot build the project due to error above.
Change the Target framework to android 11 and Target android version to android11, rebuild it.
