toDataURL not working on android browsers

Question

I have an image that the user drew on a canvas and i want to save that image on the server.

These lines work well on my ipad but not on my android(ver 2.3.3) browser

Answer 1

Unfortunately toDataURL() only work on android 3.2 or above version.

Answer 2

Unfortunately it isn't supported in your version (i think it's only supported in ICS), have a look at this issue reported

http://code.google.com/p/android/issues/detail?id=16829

There is supposed to be some sort of JavaScript implementation to add support for it, but i haven't tried it myself

Answer 3

An alternative implementation that we have used successfully on multiple Android handsets without modification is described in this blog post:

This uses the toDataURL method if it works correctly, and if not uses a javascript jpg encoding library to produce the image.
