Friends, I need your help to solve a problem.
When I open Android Studio the following error appears and I can not do anything right.
Could anyone help me?
Failed to resolve: com.android.support: appcompat-v7: 27. +
Thanks for the help!
Note: I was told that I would have to do something in gradle, but I do not know how to do this. If possible, someone can describe step-by-step the question. Thanks a lot!
