Are SVG icons supposed to work on Android?

[Ben Rubinstein]

per the subject really - I added some snazzy SVG icons into my app, for no 
better reason than that I could - but when I built to Android, one of them 
didn't appear at all, and when the other is supposed to briefly fade in and 
out again, instead a square of approximately the same size does so.

Is this a known issue? (I couldn't find any reference to it, in user guide, or 
QCC. Then again, the only reference to SVG in the - 8.1.3 - user guide is to 
say that there is a third-party library to import and export.)

TIA,

Ben
