How to use android logging (LOGD, LOGE) in NDK library

[Loic]

Hello,
I just want to log messages from my NDK library but trying to include
cutils/log.h is not working in the NDK toolchain.
what should I use ?
thanks,
Loic

I've been using this:

...
#include <android/log.h>
...
#define LOG_TAG "barabashka" // text for log tag

...
__android_log_print(ANDROID_LOG_INFO, LOG_TAG,
"resolving function %s, id %d", symbols[f_id].name, f_id);
...

You can check android/log.h for more logging function definitions:
build/platforms/android-1.5/common/include/android/log.h

use <android/log.h> instead

i tried this and got link errors -- how does one add liblog.so to the build?

You need to add '-llog' to your linker options. I'm not sure how to do
this properly, since I don't use NDK makefiles, but the log library is
along libc and others.

LOCAL_LDLIBS := -Lbuild/platforms/android-1.5/arch-arm/usr/lib -llog

Or you can use:

LOCAL_LDLIBS := -L$(SYSROOT)/usr/lib -llog
