The most complete answer is this:
To add SVG support to 2.x versions of the platform, you have two basic choices:
The first option is okay if you're just trying to make SVG work for personal uses or a limited (controllable) set of users. It's not a great option if you want to use SVG while targeting a large, uncontrolled user base.
Using a polyfill, you can render your SVG in a canavs on all versions of Android 2.x.
For a more complete example of this approach, you can refer to this blog post that discusses the use of the canvg polyfill for making Kendo UI DataViz charts (SVG-based) work on Android 2.x. Hope that helps!
