Canvas Home Page Not Showing

Canvas Home Page Not Showing. If i try this code in jsfiddle, it works. I hope you can help me.

Var ctx = canvas.getcontext (2d); View solution in original post. Make sure you have the current version of the canvas student mobile app installed and that the operating system on your mobile device is up to date.

Imageobj.onload = function () { ctx.drawimage (img, 0, 0);
