Answer 1

Have you tried to rebuild or clean your project? I think you should try that then run the app again

Answer 2

In your root element, replace:

xmlns:android="http://www.w3.org/1999/XSL/Transform"

with:

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

Also, remove xmlns="http://schemas.android.com/apk/res/android" from your root element.

Answer 3

Try syncing project with Gradle files: File -> Sync project with Gradle files.
