特别注意，编译静态库的时候你需要多加一个Application.mk,俺开始没有注意，一直不编译

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
