Answer 1

Open your Android project in Android Studio and follow the below steps:

1. Delete .gradle , .idea & build folder from the root directory
2. Delete build folder inside app module
3. Apply File -> Invalidate Caches / Restart -> Invalidate and Restart option
4. While the Android Studio is being restarted, navigate to your user folder, which generally has .gradle folder. Delete the .gradle folder in your computer's user directory.
5. Open the Android project again and see if that solves the problem.

Answer 2

In some cases Invalidate Caches / Restart was not enough:

1. Delete .gradle , .idea , & build
2. Delete build folder inside modules ( app , ..)
3. Close Android Studio
4. Delete C:\\Users\\xxxxxx\\.AndroidStudio3.X\\system\\caches
