Building android 12 and edit-config problem

When adding

<edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application/activity">
   <application android:exported="true" />
</edit-config>

in config.xml, the following error occurs when making native app with voltbuilder “Parse Error in config.xml unbound prefix: line 2”. When the added lines are removed it works well.
Could you please provide some hints

Try adding the following attribute to the widget tag:

xmlns:android="http://schemas.android.com/apk/res/android"

It should look something like this:

<widget xmlns:android="http://schemas.android.com/apk/res/android">

Thanks a lot it works.
Such additional line should be added on the web site for android 12

Please add this instruction to Building for Android 12 | VoltBuilder as it is not explained there.
