android java-native-interface logging android-ndk

You need to add

LOCAL_LDLIBS := -llog

to Android.mk

android java-native-interface logging android-ndk

Try the following in your Android.mk file:

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

android java-native-interface logging android-ndk

If you use Android Studio and gradle, it ignores Android.mk. Add this to your build.gradle file:

android {    defaultConfig {        ndk {            moduleName "your_module_name"            ldLibs "log"        }    }}
