Compiling native android library with multiple c files using ndk build errors * No rule to make target

I am having an issue compiling a shared C library into a .so for android. I've copied all the .c and .h files into the jni folder. I posted a screenshot below to show the contents of the Android.mk file as well as the folder hierarchy.
below is the output of ndk-build run in the project root folder NTRUMLS
[kenway#jackdaw NTRUMLS]$ ndk-build
make: *** No rule to make target '/media/bigdata/Android/Sdk/ndk-bundle/build/core/crypto_hash_sha512.c', needed by 'obj/local/arm64-v8a/objs/ntrumls/crypto_hash_sha512.o'. Stop.
i checked for spaces and typo's. here's the contents of my Android.mk copied directly below.

LOCAL_ARM_MODE := arm
LOCAL_PATH := $(call my-dir)
LOCAL_MODULE := libntrumls

Move

Try following

Include Protobuf Library - cocos2dx

Hi I would like to add protobufs to my project. So far I am only trying with android and have not been lucky so far.
I have placed my libs : libprotobuf.a , libprotobuf-lite.a, libprotoc.a in "Protobuf" folder right where "Classes" folder can be found.
I have generated one Proto named "Msg.pb.cc" and placed it in Classes folder.
I have placed the Protobuf .h files in the classes folder. i.e. Classes/google/protobuf/....
This is what my Android.mk looks right now.
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := libprotoc
LOCAL_SRC_FILES := ../../Protobuf/libprotoc.a

I get a lot of errors as soon as it compiles the Msg.pb.cc. Here's a few:

Somehow, I guess the files are not linked. The code is unable to find the protobuf library.
I don't know how Android.mk files are written and do not have much experience with cpp as well. This is just the result of some google searches and reading the original Android.mk file.
Any help is appreciated.

How to add static c-library (libsrtp) to Android-Project using NDK

so I'm relatively new to Android-NDK and trying to add an uncompiled c-library to android.
I've downloaded the library's source from here and followed these instructions to create a static library (.a-File) from the downloaded files using ndk-build.
So now I have a folder-structure that looks like this:
-srtp
--include (srtp.h, crypto.h)
--srtp (srtp.c...)
--obj
---local
----armeabi
-----libsrtp_static.a
In my Android-project I want to include srtp.h in a c-file inside my /jni/ folder. I've tried to just add the .a-file to the /jni folder but than it says "srtp.h no such file or direcotry". If I add the entire srtp-folder to the project and include the header with "srtp/include/srtp.h" it compiles but fails to link the source as I get the error "Undefined reference to srtp-function-call"
Here's my Android.mk (parts of it copied from Android.mk within the downloaded source):
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_LDLIBS := -llog
LOCAL_MODULE := ndk1 #name of my project
LOCAL_SRC_FILES := native.c #name of the c-source file
include $(BUILD_SHARED_LIBRARY)
LOCAL_PATH:= /home/dev/programing/srtp
common_SRC_FILES := \
srtp/srtp.c \
srtp/ekt.c \
crypto/cipher/cipher.c \
#...more files like that
common_CFLAGS := \
-DPOSIX -iquote$(LOCAL_PATH)/crypto/include \
-Werror \
-Wno-ignored-qualifiers \
-Wno-sign-compare \
-Wno-missing-field-initializers
common_C_INCLUDES = $(LOCAL_PATH)/include
# For the device
# =====================================================
# Device static library
include $(CLEAR_VARS)
ifneq ($(TARGET_ARCH),x86)
LOCAL_NDK_VERSION := 5
LOCAL_SDK_VERSION := 9
endif
LOCAL_SRC_FILES := libsrtp_static.a
LOCAL_CFLAGS += $(common_CFLAGS)
LOCAL_C_INCLUDES += /home/dev/programing/srtp/include
LOCAL_MODULE:= libsrtp_static
LOCAL_MODULE_TAGS := optional
include $(BUILD_STATIC_LIBRARY)
Any help is greatly appreciated! Thank you very much.

You need to add the reference to libsrtp_static from your lib (ndk1) declaration :
LOCAL_STATIC_LIBRARIES := libsrtp_static
Also, you don't need to copy all the strp sources to your project, only add this to your static prebuilt library definition
LOCAL_EXPORT_C_INCLUDES += /home/dev/programing/srtp/include
This path will then be automatically added to the LOCAL_C_INCLUDES of your library that is using the library.
Are you building libsrtp or just using a prebuilt static library ? If you're using a prebuilt (lib*.a), replace BUILD_STATIC_LIBRARY with PREBUILT_STATIC_LIBRARY and set only the .a as SRC_FILE:
In summary, once libstrp_static.a is built, this should work:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_LDLIBS := -llog
LOCAL_MODULE := ndk1 #name of my project
LOCAL_SRC_FILES := native.c #name of the c-source file
LOCAL_STATIC_LIBRARIES := libsrtp_static
include $(BUILD_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_SRC_FILES := /home/dev/programing/srtp/libsrtp_static.a #check path to libsrtp_static.a
LOCAL_EXPORT_C_INCLUDES += /home/dev/programing/srtp/include
LOCAL_MODULE:= libsrtp_static
LOCAL_MODULE_TAGS := optional
include $(BUILD_STATIC_LIBRARY)

Cocos2d-x extensions in an Android app

I'm having trouble using CCHttpRequest in an Android app that's part of a Cocos2d-x project. Specifically I get a bunch of build errors when building in Eclipse that I don't get when building the iOS app in Xcode.
An example build error that I receive in Eclipse (but not in Xcode) is:
`Type 'CCHttpResponse' could not be resolved`
This error is for the line:
CCHttpResponse *response = (CCHttpResponse *)data;
Both Eclipse and Xcode projects reference the same .cpp files. To make the Eclipse project aware of the Cocos2d-x extensions I did the following:
Open Project => Properties => C/C++ General => Paths and Symbols => Source Location
Click Link Folder...
Check Link to folder in the file system
Browse to the folder containing the extensions (that work in the Xcode project)
Click Ok, Apply, and Ok
Note there are some other surprising errors in my HelloWorldScene.cpp file. For example:
Symbol 'vector' could not be resolved.
I'm guessing the problem is related to how I've set-up something in Eclipse. Since I'm new to Eclipse I'm not sure what to try. Everything builds and runs fine in the Xcode project.
Edit #1: After commenting the code responsible for most of the Eclipse build errors I noticed the error:
`make: *** [obj/local/armeabi/libgame.so] Error 1`
I don't know what this means but it seems like it might be a more fundamental error than unresolved symbols.

I think Android.mk and Application.mk have some problem, Because in my application Android.mk is loading more files, and my application is running properly in both platform android and ios. You can see the differences.. it may help you. I am also using cocos2dx library.

ndk build_static_library make: Nothing to be done for `all'

I meet a problem when I build the libjpeg on android in eclipse. The jni contains Android.mk as follow:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := hello-jni
LOCAL_SRC_FILES := hello-jni.c
#LOCAL_C_INCLUDES := $(LOCAL_PATH)/jpeg8d-master
#LOCAL_STATIC_LIBRARIES := libjpeg

#include $(LOCAL_PATH)/jpeg8d-master/Android.mk
The jpeg8d is the source code I download from github. The android.mk
LOCAL_PATH:= $(call my-dir)
# ------------------------------------------------------------------

ndk-build give the tips :
make: Nothing to be done for `all'.
But if I Set the jpeg8d Android.mk BUILD_SHARED_LIBRARY,I get the libjpeg.so.
I don't know why. Can anyone help me ?

Solution:
You can redefine the library name by the LOCAL_MODULE_FILENAME. In my problem, I have set the LOCAL_MODULE_FILENAME=libjpeg, but I don't add the
APP_MODULES:=cocos_jpeg_static (remember cocos_jpeg_staic is the LOCAL_MODULE not the LOCAL_MODULE_FILENAME) into the Application.mk which is in the jni directory not in the jpeg8d-master directory.
I generate the libjpeg.a when i add this line into the Appliction.mk
APP_MODULES:=cocos_jpeg_static
