One of the android Modules (AudioFlinger) has support for verbose logging (with Tag=AudioFlinger).
Question is how can I see those logs in the logcat?

I did the setprop log.tag.AudioFlinger VERBOSE – but it doesn’t seem to work. Do I need to change something and then rebuild the android source again?

    The logcat documentation doesn’t really help. But with more digging I was able to find the answer, as I was expecting the VERBOSE logging is by default OFF at compile time.

    Looking at the cutils/log.h helps to find the answer:
    http://www.netmite.com/android/mydroid/system/core/include/cutils/log.h

    /*
 * Normally we strip LOGV (VERBOSE messages) from release builds.
 * You can modify this (for example with "#define LOG_NDEBUG 0"
 * at the top of your source file) to change that behavior.
 */

    So to enable VERBOSE for any source file/module : We have to define LOG_NDEBUG as 0
