NDK 编译和使用静态库、动态库

NDK 编译和使用静态库、动态库
情况一：编译静态库
情况二：编译动态库
情况三：编译动态库+静态库
情况四：已有第三方静态库（动态库），编译静态库（动态库）

默认所有代码和文件在$project/jni下，否则特殊说明。
情况一：编译静态库
文件Android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE    := hello-jni
LOCAL_SRC_FILES := hello-jni.c
include $(BUILD_STATIC_LIBRARY)

文件Application.mk:
APP_MODULES :=hello-jni

情况二：编译动态库
文件Android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE    := hello-jni
LOCAL_SRC_FILES := hello-jni.c
include $(BUILD_SHARED_LIBRARY)
情况三：编译动态库+静态库
文件Android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE    := mylib_static
LOCAL_SRC_FILES := src.c
include $(BUILD_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE    := mylib_shared
LOCAL_SRC_FILES := src2.c
LOCAL_STATIC_LIBRARIES := mylib_static
include $(BUILD_SHARED_LIBRARY)
情况四：已有第三方静态库(动态库)，编译静态库(动态库)
文件Android.mk:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := thirdlib1      # name it whatever
LOCAL_SRC_FILES := $(TARGET_ARCH_ABI)/libthird1.a     # or $(so_path)/libthird1.so
#LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
include $(PREBUILT_STATIC_LIBRARY)    #or PREBUILT_SHARED_LIBRARY
include $(CLEAR_VARS)
LOCAL_MODULE    := mylib_use_thirdlib
LOCAL_SRC_FILES := src.c
LOCAL_STATIC_LIBRARIES := thirdlib1       #or LOCAL_SHARED_LIBRARY

include $(BUILD_SHARED_LIBRARY)   #如果编译静态库，需要Application.mk
用cd命令移至jni目录，运行/mnt/500G/public/NDK/android-ndk-r7b/ndk-build命令，这时命令行中可能会出现编译错误，比如头文件找不到，函数找不到等等，细心找找就能改掉。

编译成功后，在工程目录下libs/x86中就会生成你想要的.so库。
