What is "Safe Delete" in Android Studio?
With Safe Removal, Android Studio will search if your "WebViewA" is used in another file or not, so it won't throw any errors if you remove it.
For example, if you use the WebViewA class in the MyActivity class and then you delete the WebViewA class without safely deleting, a new error will appear in the MyActivity class.
This is an example of safe deletion:
I tried to delete the BluetoothUtility class and I used safe delete and then found that there are 2 BluetoothUtility modes in android studio
After selecting View Usages, I can find that I was using BluetoothUtility in the MyActivity class. And I can refactor as well.
Hope my explanation is clear enough! :)

Safe deletion works in Android Studio in the same way as it does in other IntelliJ IDEA-based development environments.
It says that
You can safely remove classes, interfaces, methods, fields and parameters, keeping your code running and error free. The Safe Delete refactoring finds all uses of the selected symbol in the open project, or simply deletes the symbol if no search is found.
