I'd like to create two .so file within a single .mk file. But the following codes fails because there should not be a space in LOCAL_MODULE. So is there a way out?
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := gpio hello-jni
LOCAL_CFLAGS := -Werror
LOCAL_SRC_FILES := gpio.c hello-jni.c
LOCAL_LDLIBS := -llog
include $(BUILD_SHARED_LIBRARY)
I just got it works using the following codes.
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := gpio
LOCAL_CFLAGS := -Werror
LOCAL_SRC_FILES := gpio.c
LOCAL_LDLIBS := -llog
include $(BUILD_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := h ello-jni
LOCAL_CFLAGS := -Werror
LOCAL_SRC_FILES := hello-jni.c
LOCAL_LDLIBS := -llog
include $(BUILD_SHARED_LIBRARY)

While transforming my project from eclipse to AS.
I got a fatal error which caused by "the lib not found " problem.
My project contains jni codes,compiled by ndk build system and managed by the "Android.mk" file.
After transformed I found that two of the libraries(.so) was not packaged into the apk file while other libraries are packaged correctly.
Here is part of the content of "Android.mk" file,all libraries are packaged but "curl" and "jsqlite".The two files do exist in the right path.Is there any suggestion,thks!!

I am trying to use pjsip on android.. after ./configure-android and make dep and make commands, static libraries were generated 13 of them.
I used the include folder which is copied inside jni folder. The content of android.mk in jni folder is as follows:

I wrote a simple one line c file that only includes a header file inside include folder. Then i run ndk-build from the project directory and get no such file for the header file which is present inside the include folder. There is no application.mk.. What am i missing?
EDIT
the '.' represents the current directory.. "include" folder is inside jni folder
There are several issues here:
1) Each prebuilt static library should have its own module definition, i.e. your Android.mk should look like:
include $(CLEAR_VARS)
LOCAL_MODULE := libpj
LOCAL_SRC_FILES := libpj-arm-unknown-linux-androideabi.a
include $(PREBUILT_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := libpjlib-util
LOCAL_SRC_FILES := libpjlib-util-arm-unknown-linux-androideabi.a
include $(PREBUILT_STATIC_LIBRARY)
... etc
Note that the module name doesn't have to be exactly the same as the file path, which makes things a little clearer for the rest.
2) That '.' will refer, at build time, to the current directory where you invoke ndk-build, you need to use $(LOCAL_PATH)/include instead to refer to the right include path (assuming your Android.mk is under jni/ too). I.e.:
include $(CLEAR_VARS)
LOCAL_MODULE := dummy_pjsip_jni_module
LOCAL_SRC_FILES := dummy_pjsua.c
LOCAL_EXPORT_C_INCLUDES += $(LOCAL_PATH)/include
LOCAL_C_INCLUDES += $(LOCAL_PATH)/include
LOCAL_STATIC_LIBRARIES := libpj libpjlib-util libpjmedia libpjmedia-audiodev \
libpjmedia-codec libpjmedia-videodev libpjnath \
libpjsdp libpjsip libpjsip-simple libpjsip-ua \
libpjsua2 libpjsua

I want to use native libraries in my Android project and I try compiling them. The error I found is caused from the incompatible file extensions. They are .c .h .m4 .y and others extensions.

when i compile in Eclipse, it warned that there are unsupported source file extensions for the module i described in Android.mk.
How should I do for the solution?
Using $wildcard to list all files in lib build directory is not a good practice. When you work with so many open source libraries it's much easier to prepare and use standalone toolchain for NDK instead of improvizing the Android.mk.
I'm try to create android jni project with structure.
I want create static library test_module and include it to main shared library monitor
jni directory contain
jni

ndk-build fail with error

Sorry for bad English.
Please help.
I found answer. See diff's
jni/Android.mk
LOCAL_PATH := $(call my-dir)
MY_ROOT := $(LOCAL_PATH)
include $(call all-subdir-makefiles)
include $(CLEAR_VARS)
LOCAL_PATH := $(MY_ROOT)

Is this the correct format to specify the Android.mk?Is there any syntax errors? I couldnt find any source for clearing this doubt.Thanking you in advance.
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := imageprocessing
LOCAL_SRC_FILES := imageprocessing.c
LOCAL_LDLIBS := -lm -llog -ljnigraphics
include $(BUILD_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := libfreeimage
LOCAL_SRC_FILES := libfreeimage.so
include $(PREBUILT_SHARED_LIBRARY)
and in the C code have
#include <android/libfreeimage.h>
since u r creating a shared library from an existing shared library: So u need to first give the pre-built shared library part first then u can create ur own library. so ur code should look like this:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := libfreeimage
LOCAL_SRC_FILES := libfreeimage.so
include $(PREBUILT_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := imageprocessing
LOCAL_SRC_FILES := imageprocessing.c
LOCAL_LDLIBS := -lm -llog -ljnigraphics
include $(BUILD_SHARED_LIBRARY)
Well,
I got the solution from
http://www.kandroid.org/ndk/docs/PREBUILTS.html
Thank you for your valuable time Subrat nayak,thanks a lot
