Missing "exported" attributed in manifest while generating APK

[AntonioTangeloGames]

After the Behavior changes in Android, If your app targets Android 12 or higher and contains activities, services, or broadcast receivers that use intent filters, you must explicitly declare the "android: exported" attribute for these app components.

This is not happening right now, failing when the apk is uploaded to android. This attribute should be added into the manifest when it is generated in the class "AndroidNotificationPostProcessor" line 118 approx.

https://developer.android.com/about/versions/12/behavior-changes-12#exported

Is happening in Android, Unity 2020.3.20f, "Mobile notification package" version 1.4.2 ( the last when this was written )

Can confirm the issue, I'm receiving a warning that my game will not be downloadable by Android 12 users. The receiver that presented the problem is com.unity.androidnotifications.UnityNotificationRestartOnBootReceiver. My solution was to provide a customized AndroidManifest in my unity project to avoid this issue with the following content:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.unity3d.player"
          android:installLocation="preferExternal" android:versionCode="1" android:versionName="1.0">
    <supports-screens android:smallScreens="true" android:normalScreens="true" android:largeScreens="true"
                      android:xlargeScreens="true" android:anyDensity="true"/>
    <application android:theme="@android:style/Theme.NoTitleBar.Fullscreen" android:icon="@drawable/app_icon"
                 android:label="@string/app_name">
        <activity android:name="com.unity3d.player.UnityPlayerActivity" android:label="@string/app_name"
                  android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
            <meta-data android:name="unityplayer.UnityActivity" android:value="true"/>
        </activity>

        <receiver
                android:name="com.unity.androidnotifications.UnityNotificationManager"
                android:exported="true" />
        <receiver
                android:name="com.unity.androidnotifications.UnityNotificationRestartOnBootReceiver"
                android:exported="true"
                android:enabled="false">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

Thanks! it should work.
We have a custom manifest as well, but we don't have on it the receiver for mobile notification.
We could add it and fix the issue, but I think that this is something that the package should provide to us.

[vitordealmeida]

Agreed, just shared a quick workaround that worked for us

The issue is solved in 1.5.0, but the tag is not modified yet to 1.5.0 so you cannot update yet, maybe they forgot to add it

This issue is fixed in master.
