I am using the trial version of Xamarin Studio for my final year project consisting an android application. Everything went smooth initially. But today right after updating
It's a recent change/bug in Xamarin.Android that expects to be used with Android tools rev. 22 or later where appt has been moved around in the sdk directory (from tools to build-tools). You need to go into the android sdk manager and update the SDK tools to revision 22 (or better) and also install the new build-tools package.
