I am trying to implement CrossFadeDraweLayout using https://github.com/mikepenz/CrossfadeDrawerLayout which is basically a subpart of the project under the name Material Drawer available on GitHub.
I have gone through all the code provided and I am not able to import the following libraries
com.mikepenz.materialdrawer.accountswitcher.AccountHeader;
com.mikepenz.materialdrawer.accountswitcher.AccountHeaderBuilder;
com.mikepenz.materialdrawer.util.UIUtils;
Also can anyone explain the point of the custom library that he has added in his app for CrossfadeDrawerlayout
