Thanks Dianne, you answered my question already :-) I thought there would be a switch, such as a macro definition like "LOG_NDEBUG" for Log.v() in Java code as well. Then I found out it is not the case, different pieces of Java code are in charge of turning on/off verbose log on themselves. Like you said, they are always put in if() wrappers.
I also thought of using an environment variable as one-stop switch to turn on/off verbose log for all source files during compilation. Then I realized it might not going to be useful, because people, or at least I only debug one or two modules at one time. And loads of verbose output from other modules in "adb logcat" are just going to be annoying. /Song On Apr 16, 10:27 am, Dianne Hackborn <hack...@android.com> wrote: > I'm not sure what you are asking.
