PolylineDecoder.decode yields a StringIndexOutOfBoundsException exception. Size of string is 1256 (incremented in the first do-while loop) yet in the second do-while loop of the decode function there is an additional encoded.charAt(index++). AS the string has size 1256 chatAt(1256) yields an exception.

@sterpumihai have you found a fix for this? Did removing ++ from 2nd look fixed it for you?
