> //This following javascript code should determine if WebGL is available. On versions of Android prior to 5 (Lolipop), WebView didn't support WebGL, so all pre-Lolipop android devices should return "false" on this WebGL feature availability check. However, some pre-Lolipop devices are returning "true", which is incorrect.
