I am new to Android Studio, however I am unable to change the background color of buttons. My guess is tat I'm dealing with a faulty installation.. I tried to uninstall Android Studio, but the uninsall.exe file seams to be missing:
How can I uninstall Android Studio without an uninstaller?
Use the search engine in the file explorer. Enter the name of the program to remove and delete the directories that will appear.
Another way:-
Search in startup menu %userprofile%
Then delete the a) .android, b) .androidstudio
Then reinstall the android studio again.
I hope it works.
