and my Android.mk

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := Hello
LOCAL_CFLAGS    := -Werror
LOCAL_SRC_FILES := lib.c


include $(BUILD_SHARED_LIBRARY)

and my Application.mk
APP_PROJECT_PATH := D:/Java_2/workspace_indigo/JniTest

simple like it said in the docs , but still doesn't work .. what is it why its not working what im missing ?

Obviously, your Android.mk file is located in the wrong place, because it's current location is:

native/Android.mk

and your build script expects it to be in

src/jni/Android.mk

You have to change the script or copy/move the file.

Thanks , how did you spot this ? – user63898 May 17 '12 at 09:52

i've just noticed the error message complained about `Android.mk` and used 'search' button to find if it's mentioned anywhere else. fortunately you have included your directory listing =) – lenik May 17 '12 at 10:06
Am also getting this error with android-ndk-r12b, but there are many Android.mk files in subdirs. Do you have any suggestions on which file I need to copy to ~/jni/Android.mk? – user8128167 Aug 12 '16 at 15:16
We don't use `src/jni/...` directory structure. (And we don't work for the tools; we expect them to work for us). How do we make the tools use our directory structure? – jww Aug 26 '18 at 03:17
@lenik - Based on the question's output with the directory structure, the original question is not using `jni/` either. They seem to be the same problem and same error message to me. Perhaps I am missing something obvious? – jww Aug 26 '18 at 11:31
