JNI中调用第三方提供的so文件

最近做JNI调用第三方so中的c方法，总是报找不到so文件，今天终于解决了，总结如下：

一、在根目录下建立Android.mk文件

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_SRC_FILES := $(call all-subdir-java-files)

LOCAL_PACKAGE_NAME := xxx

LOCAL_JNI_SHARED_LIBRARIES := libxxx

include $(BUILD_PACKAGE)

IN_NDK := true

WITH_PLAYER := true

include $(call all-makefiles-under,$(LOCAL_PATH))

 二、在项目下jni文件夹里Android.mk;

  include $(all-subdir-makefiles)

三、在jni文件夹下新建目录prebuilt（或者其他别名）将所有的第三方库复制进去，并建Android.mk文件

LOCAL_PATH := $(call my-dir)

 

include $(CLEAR_VARS)  

LOCAL_MODULE := libx264  

#LOCAL_STATIC_LIBS  

LOCAL_SRC_FILES := libx264.a  

include $(PREBUILT_STATIC_LIBRARY)   #（静态库）

include $(CLEAR_VARS)

LOCAL_MODULE := libLinePhone

LOCAL_SRC_FILES := libLinePhone.so

include $(PREBUILT_SHARED_LIBRARY)  #（动态库）

四、在jni文件夹下新建目录jni（或其他别名）中放所有的c文件（含调用及本地方法的），Android.mk写法如下:

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

IN_NDK := true

LOCAL_CFLAGS := -D__STDC_CONSTANT_MACROS

WITH_CONVERTOR := true

WITH_PLAYER := true

ifeq ($(WITH_PLAYER),true)

LOCAL_CFLAGS += -DBUILD_WITH_PLAYER

endif

ifeq ($(WITH_CONVERTOR),true)

LOCAL_CFLAGS += -DBUILD_WITH_CONVERTOR

endif

LOCAL_C_INCLUDES += xxx

 LOCAL_SRC_FILES := xx.cpp

ifeq ($(IN_NDK),true)

LOCAL_LDLIBS := -llog

else

LOCAL_PRELINK_MODULE := false

LOCAL_SHARED_LIBRARIES := liblog

endif

LOCAL_SHARED_LIBRARIES :=xxxxx

LOCAL_STATIC_LIBRARIES :=xxxxx

LOCAL_MODULE := xxx

include $(BUILD_SHARED_LIBRARY)
