So I am working with Android Studio and I need a countdown timer.
So far i have searched and found all kinds of code lines that do not work , or do not do exactly what I wanted the app to do.
I want the timer to countdown , if the user answers incorrectly , the time left will be reduced , and if the user answers 3 correct , then time will be added.
Can anyone give me a code and explain what it does , do I need anything extra?
and how i can modify it to my needs.
