title: Difference between google material library and design support library
body: <p>I was trying the new material design components on android such as the bottom app bar but i discovered that every MDC was existing in the android design support library but also in another library called <code>com.google.android.material</code> and the code was pratically the same (in the design library the code was documented unlike the other), so what is the difference between these two library?</p>
