title: How to change default app icon shape in Android Studio
body: <p>I started using Android Studio recently and I found one thing different (notably) that unlike in Eclipse, Android Studio does not provide any option to choose <em>app icon</em> and its <em>shape &amp; size</em> while creating a new app. 
  While finalizing my app development I tried to change default 'ic_launcher.png' with my own image but I am not able to change its shape (which is <em>square</em> by default) to <em>circular</em>.</p>
  
  <p>So my question is - Is there any way of changing app icon shape in Android Studio ?
  And if this question is already been solved on some other thread then please share that link with me. (P.S.- I tried to search with similar question here but couldn't find probable solution, therefore posting this question on my own)</p>
