  • 0

My empirical experiment shows that if I setSpan(o, start, end) from start to end of a string, where end is String.length() - 1, the last character isn’t covered.

When I changed end to exactly String.length(), the entire string is covered and… I don’t even get an “out-of-bound” exception.

Unfortunately, there is nothing in the documentation regarding this particular issue.

Can you confirm my observation? (or prove me wrong?)

    end is exclusive. 0, 2, for example, is everything from 0 inclusive to 2 exclusive which is 0 and 1.
