Hi I am building an C++ native library based on the android NDK tool. However, I couldn't figured out how to print log in the C++ file to Android logcat. 
here is what I have done. 
I have follow this guide. 
to add the 
    __android_log_print(ANDROID_LOG_INFO, "log", "hi logg");
include  android/log.h
and
android {
defaultConfig {
    ndk {
        moduleName "modulename"
        ldLibs "log"
    }
}
the app is able to compile but there's no log printed. Can someone help me?
