Today, I have updated this library to compatible with latest Appcompat ( V7:26.1.0 ) and Design(26.1.0) support libraries . I have only updated the source code, not on Bintray, that means you will have to copy-paste the /materialpreference folder from Github in your project . You can check the example project how to include a library project ( Download the project as zip from github -> unzip -> open it on Android Studio ) .
I will update here after a new version will be available to use via gradle .
Try it , like the project on Github and let me know if you face any issue.
