I found the solution, there was no issue with the library I just needed to update my support dependency in gradle

[danielidt]

Ok guys, I think i fixed it. I had to add implementation 'com.android.support:appcompat-v7:26.0.2' to my dependencies in file app/build.gradle

I was using compileSdkVersion = 27 and found that I could keep that as well. it also works with compileSdkVersion = 26

It also works with other versions of implementation 'com.android.support:appcompat-v7:{version}' included as long as 26.0.2 or 26.0.1 is in there also. Not sure what the best configuration is since im not an android dev but wanted to share the solution i found.
