title: Developer Console: Android Security Alert libpng using old version cocos2d-x 2.2.6 game
body: <p>Developer console is showing security alerts on all of my cocos2d-x v2.x games with detail of using old libpng.</p>
  
  <p>In cocos2d-x v2.2.6, I have found libpng two files <strong>png.h</strong> &amp; <strong>pngconf.h</strong> with v1.2.46 and as resolution is suggested to use 1.2.56 latest version for this one.</p>
  
  <p>I have submitted a build with these two updated files to see if that was the resolution. Will post if got SUCCESS.</p>
  
  <p>Please if anyone have found other solution, then share. </p>
