Firstly I added the exoplayer dependency to my build. After that I made a xml layout with a custom controller and then I wanted to add app:fastforward_increment & app:rewind_increment. But every time I try to build it throws this error message :
AAPT: error: attribute fastforward_increment not found.
I tried to resolve this issue by adding the other dependecies as they were suggesting in one of the forums but it didn't work. Do you know what's causing the issue and how to solve it?
