Are there Illegal Logcat Tags?

Question

I am the developer of Log This on Android Market, and a feature I am implementing requires me to use a URL parser (or write a string parser more like) that can parse a string for tags. I am not sure if I could use quotes to surround the tags, or if I can find an illegal character in the tags I would just use that. Are there characters that are not allowed in Logcat Tags? Since it takes any string I'm going to assume that it takes anything, but I can't find anything on this subject.

Thanks, Mgamerz

Answer 1

Some that I can think of

• If the tag is > 23 characters long.
• If the tag used by the system already use isLoggable(). The documentation is not clear on this bit so you will have to check it for yourself. Basically it calls a native function, whose implementation may vary across OEMs.
