Android studio automatically creates 2 value folder, value and value-v21. Both have a style.xml
If I'm understanding it correctly, the phone will only choose the style from v21 if my phone uses the api of 21 or above.
I deleted the v21 folder, and everything seems to be working fine on my android 5.0 phone. I'm wondering why the v21 is even there? Is there something special I have to do or should do or can do for api21+?
