android:exported needs to be explicitly specified for <activity>

Question

I've explored a lot and i found out that in all the activities we need to specify the android:exported parameter. I've added the param in all my activities in manifest, but i'm still getting this error.

Manifest merger failed : android:exported needs to be explicitly specified for <activity>. 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. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details.
