I'm trying to test Android Gstreamer. So I installed and configured path  SDK
<https://gstreamer.freedesktop.org/data/pkg/android/1.8.1/>  , got  tutorial
source
<http://docs.gstreamer.com/display/GstSDK/Installing+for+Android+development> 
, modify path in tutorial's Android.mk, and do ndk-build at
android-tutorial-1/jni. But I got

$ ndk-build
