title: Empty cocos2D-x project is too big
body: <p>I want to create a very small (in apk size) Android game, I hope is not more than 3mb, so anyone with low avaiable space in the phone can play it.
  I can do it with libgdx but I want to use cocos2d-x.</p>
  
  <p>The problem is that I built the start template project that only has the cocos logo image, using Android Studio in release mode and the APK built is 3.2Mb. Is too big. I run the analysis and the .so file size is 2.4mb.</p>
  
  <p>I'm missing some optimizations or something? I'm new in cocos2d-x so maybe there is something I don't know.</p>
