title: Customize Firebase-ui auth Android
body: <p>Recently Firebase open sourced their Firebase-Auth drop in Authentication System on Github. <a href="https://github.com/firebase/FirebaseUI-Android" rel="noreferrer">Firebase-ui auth Github</a>. Although a very good step they haven't released any documentation regarding how can we customize all the UIs present in the package. One option to do so is, clone the full repo and then dig down the code, modify it and then include each and every class, dependency in our Android project. Is there any simpler solution for that?</p>
