You uploaded an APK or Android App Bundle which has an activity, activity alias, service or broadcast receiver with intent filter, but without ‘android:exported’ property set. This file can’t be installed on Android 12 or higher. See: developer.android.com/about/versions/12/behavior-changes-12#exported
Solution One
Backup your entire project file.
Save AndroidManifest file in a notepad.
Solution Two
Open AndroidManifest.xml file
Check and locate
<activity
android:name="com.YourActivity"
ndroid:screenOrientation="portrait"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.DIAL" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
Compare this new added code above and remove all.
If the above solution doesn’t work then add this line of code below.
android:exported="true"> //each activity intent.
