Exception when use NumberPickerDialog.integer()

[polis]

Hi,

Thanks for that lib!

I used the NumberPickerDialog in my code.
After select the number and press ok It shows error in console:

Getting the same error. Any solution to this yet?

Turns out, if you remove

integerNumberPicker.animateInt(value);

from your code, it works now.
