//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.
var canvas = document.createElement('canvas');
canvas.screencanvas = false;
var supportsWebGL = !!window.WebGLRenderingContext &&
(canvas.getContext('webgl') || canvas.getContext('experimental-webgl'));
