The error:

java.lang.StringIndexOutOfBoundsException: length=10; regionStart=11; regionLength=10

is because you're trying to get a substring from position 11 in a string that is only 10 chars long. If the value in the MaskedEditText is "21/12/2018" that is 10 chars, so not sure why you're doing a SubString starting at char 11...

- Colin.
