I've been playing with Azure Mobile Services on Mono for Android (and on MonoTouch too).
One thing that stumped me for a little while was a problem where I just couldn't talk to the server - all calls would fail with:
The request could not be completed (Send failure)
Eventually I worked out that:
- Make sure you've got INTERNET permissions in your app Manifest
- Make sure you are using http and not https for the service address
I'm not sure why https is not currently working - must be some SSL/certificate-level error?
