Getting android:exported needs to be explicitly specified for element even after adding the android:exported value

Question

I am getting below errors on my Xamarin Forms android project when updating the target version to 33.

Severity Code Description Project File Line Suppression State Error android:exported needs to be explicitly specified for element <service#crc6494e14b9856016c30.PNFirebaseIIDService>. Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined.

I have added android:exported values on Manifest and MainActivity files and close the project and did clean and rebuild.

Manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionName="2.5" package="com.companyname.appname" android:installLocation="auto" android:versionCode="16">

            <intent-filter>
                <data android:scheme="https" android:host="www.smartwcm.com" android:pathPrefix="/domain" />
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
            </intent-filter>
            <intent-filter>
                <data android:scheme="http" android:host="www.smartwcm.com" android:pathPrefix="/domain" />
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
            </intent-filter>
        </activity>
        <provider android:name="android.support.v4.content.FileProvider" android:authorities="com.companyname.appname.fileprovider" android:exported="false" android:grantUriPermissions="true">
            <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/file_paths"></meta-data>
        </provider>
        <receiver android:name="com.google.firebase.iid.FirebaseInstanceIdInternalReceiver" android:exported="false" />
        <receiver android:name="com.google.firebase.iid.FirebaseInstanceIdReceiver" android:exported="true" android:permission="com.google.android.c2dm.permission.SEND">
            <intent-filter>
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
                <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
                <category android:name="${applicationId}" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

I have added exported value on activity, provider, FirebaseInstanceIdInternalReceiver and FirebaseInstanceIdReceiver.

MainActivity

[Service(Exported = true)]
[IntentFilter(new[] { "com.google.firebase.MESSAGING_EVENT" })]
public class FirebaseNotificationService : FirebaseMessagingService
{

}

[Service(Exported = true)]
[IntentFilter(new[] { "com.google.firebase.INSTANCE_ID_EVENT" })]
public class FirebaseRegistrationService : FirebaseInstanceIdService
{

}

Added the same on FirebaseRegistrationService and FirebaseNotificationService under MainActivity.

But the error shows add it on PNFirebaseIIDService and PNFirebaseMessagingService. But these properties are not added on my project.

Answer 1

Hello,

Upon investigation, PNFirebaseIIDService and PNFirebaseMessagingService are the classes in Plugin.FirebaseCloudMessaging. This plugin has not been updated since 2020, therefore, it is not compatible with higher versions of Android.

Please refer to and Remote Notifications with Firebase Cloud Messaging, and use Xamarin.Firebase.Messaging as an alternative.

Best Regards,

Alec Liu.
