You uploaded an APK or Android App Bundle without the 'android:exported' property set

just having a freakout moment while upgrading my app from android api 30 to 33, when i upload it on play console i am getting the error which says

> You uploaded an APK or Android App Bundle without the 'android:exported' property set.

even when i have set the 'android:exported' property. but it still shows the same error.

As for new android version , you need to set android:exported for each activity , service and receiver in manifest file . In you file , I am able to see android:exported for a few activities only not all .. So kindly consider 2 points here which can fix your issue

1. Set android:exported to each activity , service and receiver in your manifest
2. Errors you are getting for other activity , service and receiver which is part of some library and not your code so either upgrade your library to latest version if they have added support for new android version or re-register those activity , service or receiver in your manifest with android:exported tag
