I developed an application using Xamarin.Forms 3.4 The application is working, but with the new version of Android 12 this application was automatically removed from the devices and when it has to be installed again from the PlayStore store, an error occurs.
I tried to deploy visual studio to a device with android 12 and the following error occurs:
ADB0010: Mono.AndroidTools.InstallFailedException: Unexpected install output: Failure [INSTALL_PARSE_FAILED_MANIFEST_MALFORMED: Failed parse during installPackageLI: /data/app/vmdl1472364015.tmp/base.apk (at Binary XML file line #28)
: com.onesignal.GcmBroadcastReceiver: Targeting S+ (version 31 and above) requires that an explicit value for android:exported be defined when intent filters are present]

Searching the internet I found this article: https://medium.com/androiddevelopers/lets-be-explicit-about-our-intent-filters-c5dbe2dbdce0
This article mention to add export in activity, receiver and ect. I added this attribute but the deploy continues with an error, if I use a device with an android version lower than 12 it works.
My activity is like this:
[Activity(
Label = "My App",
Icon = "@drawable/icon",
Theme = "@style/Theme.Splash",
MainLauncher = true,
LaunchMode = LaunchMode.SingleTask,
Exported = true,
ConfigurationChanges = ConfigChanges.Orientation | ConfigChanges.ScreenSize | ConfigChanges.Locale | ConfigChanges.LayoutDirection
)
]
Manifest:

BroadcastReceiver:
[BroadcastReceiver(Name = "com.my_app.app.BootBroadcast", Enabled = true, Exported = false)]
[IntentFilter(new[] { Intent.ActionBootCompleted })]
public class BootBroadcast : BroadcastReceiver
I honestly don't know what else to do
