The plugin cordova-plugin-customurlscheme
throws the same error that cordova-plugin-x-socialsharing
:
android:exported needs to be explicitly specified for element <activity#your.bundle.id.MainActivity>.
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.
So I think maybe you want to add it to the list of plugins which have been reported to cause problems published on Building for Android 12 | VoltBuilder an add your magic -android12
flag to it
