[mono-android] Using DatePickerDialog

[Tomasz Cielecki]

I just made a small sample here:
https://github.com/Cheesebaron/MonoDroid.DatePickerSample

But what your exception is saying that some of the values you have fed
the DatePickerDialog are invalid:
java.lang.IllegalArgumentException: current should be >= start and <= end

I think it is the 12 you have put in for the month. Maybe it expects
11 as the months might be 0 indexed. Just like the sample shows
date.Month - 1.
