The JavaDoc says that if the "...count is negative then the characters before index are measured in reverse order. This allows for measuring the end of string." However, the native code doesn't work its way backwards from the given index when the count is negative. It always passes Skia the substring starting from index and the absolute value of count. Its better to fix the JavaDoc rather than the behavior, since this API is public and has been this way for some time. It is also used by TextUtils.ellipsize indirectly, so its best to avoid breaking that sensitive code. Change-Id: I8bd51def6ec98251e355370710eb44f58fb737c4
