NoClassDefFoundError when using BetterPicker's CalendarDatePickerDialog

[mousewithjetpack]

When running BetterPicker's CalendarDatePickerDialog on Android 3.0, I get a NoClassDefFoundError for AccessibilityNodeInfo.

Here is the relevant part of the LogCat:

I looked at this line in your code:

com.nineoldandroids.animation.PropertyValuesHolder.getPropertyFunction(PropertyValuesHolder.java:415)

and I added a new catch block that catches the NoClassDefFoundError that line 415 throws, and just swallow the exception, and then the CalendarDatePickerDialog works on Android 3.0.

Not sure if this is something you want to look into, but I thought I would let you know.
