If you are using any Custom-View/Component-View, you must need to set a theme to that view.

You need to fix these xml errors (maybe alt + enter help to fix them)

Answer 3

I was getting the same error in version. Android Studio Electric Eel | 2022.1.1 Patch 1

I did the following steps and only one worked for me:

• Invalidate Caches ❌
• Clean Project ❌
• Rebuild Project ❌
• Remove build Folder ❌
• Remove .idea Folder ✅

Make sure you're using the Android Studio with the latest version.
