title: Paid and Free versions of android app
body: <p>I am wondering what is the best way to have two different versions of an android app. I would like to have version of my app with ads and one without ads (the paid one). What is the easiest way to achieve this ? I have found something called version flavours <a href="https://developer.android.com/tools/building/configuring-gradle.html" rel="nofollow">here</a> but since I am new to android development I am not sure if that is what I want. Please any suggestions for addressing this ?</p>
