This library crashes the app when running in pseudolocale

When I turned on pseudolocale for my app and tried to open the calendar picker view I got this crash:

Solution is to set the date strings to not be translatable:

<string name="month_name_format" translatable="false">MMMM yyyy</string>
<string name="month_only_name_format" translatable="false">MMMM</string>
<string name="year_only_format" translatable="false">yyyy</string>

[edenman]

yeah....except we do want those to be translatable, for instance in Korean the month_name_format is:

@edenman so "translatable=false" would only affect pseudolocale setting but if the locale on the device is Korean then Android will still pick up the string that you did override in values-ko. I already have similar examples in my project and works perfectly fine but couldn't override the ones from this library.
