Logging values of variables in Android native ndk

Question

I set up logging with C++ in Android NDK.

I can print a message to logcat like this:

__android_log_write(ANDROID_LOG_INFO, \"tag here\", \"mess         


        

Answer 1

Take advantage of the variadic log print function you have available. For my own code, I provide a LogInfo() function to make it simple. Of course there are several options available to you here.

void LogInfo(const char *sTag, const char *fmt, ...)
{
  va_list ap;
  va_start(ap, fmt);
  __android_log_vprint(ANDROID_LOG_INFO, sTag, fmt, ap);
  va_end(ap);
}
