A key step, remember that after clicking 'Refactor' in step 4, Android Studio will not rename and refactor immediately, it will display a preview of the refactoring in the 'Find' bar at the bottom, we click 'Do Refactor', Just do the refactoring now.

You can use Ctrl + Shift + R to globally search the package name before replacement to see if there are any omissions. If so, just press Ctrl + Shift + R to replace
