can anybody suggest me what can be a problem?

Here is my Android.mk

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := fpdfembedsdk

LOCAL_SRC_FILES := FoxitEMBSDK_EMBJavaSupport.cpp

LOCAL_C_INCLUDES := $(NDK_APP_PROJECT_PATH)/include

LOCAL_LDLIBS := -llog -g -L. -ljnigraphics

#fill in the foxit library here

LOCAL_LDLIBS := $(NDK_APP_PROJECT_PATH)/bin/libfpdfemb_android.a

include $(BUILD_SHARED_LIBRARY)

Please include the header for this function which is
#include<android/log.h> in the corresponding file which gives the error.

[Hitendrasinh Gohil]

include header in Android.mk?

LOCAL_LDLIBS := -llog -g -L. -ljnigraphics

#fill in the foxit library here

LOCAL_LDLIBS := $(NDK_APP_PROJECT_PATH)/bin/libfpdfemb_android.a

Your later assignment := removed the -llog, add the -llog to the later LOCAL_LDLIBS

or change that to +=

Hi chan thanks,

LOCAL_LDLIBS := -llog -g -L. -ljnigraphics

#fill in the foxit library here

LOCAL_LDLIBS += $(NDK_APP_PROJECT_PATH)/bin/libfpdfemb_android.a

this way?

[Chen Yang]

yes, please have a try.

[Hitendrasinh Gohil]

If i change it to  LOCAL_LDLIBS += $(NDK_APP_PROJECT_PATH)/bin/libfpdfemb_android.a  then i m getting the following exception.

can anybody pls point me what is the problem?

[David Turner]

That's normal, the libfpdfemb_android.a library wasn't there.

If this is prebuilt, why aren't you using PREBUILT_STATIC_LIBRARY instead? See $NDK/docs/PREBUILTS.html

If it is not a prebuilt, you need to use LOCAL_STATIC_LIBRARIES to indicate that you libfpdfembedsdk.so depends on it, otherwise the build system may try to build it before the static lib.

[Hitendrasinh Gohil]

Hey David you are right but after cleaning the project i forgot to p
ut the lib in bin directory.

Below thread has solved my problem.
