• 目錄結(jié)構(gòu)

• 生成.a靜態(tài)庫

static.h

int add( int x, int y);

static.cpp

#include "include/static.h"
int add( int x, int y)
{
     return x + y;
}

• Android mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE    := static_add
LOCAL_SRC_FILES := static.cpp
include $(BUILD_STATIC_LIBRARY)

• 使用靜調(diào)庫

image.png

share.h

# include "static.h"
int test_add( int x, int y);

靜態(tài)庫的頭文件 ，static.h

share.cpp

# include "include/share.h"
# include "include/static.h"
# include "log/log.h"

int test_add( int x, int y)
{
     // 調(diào)用static里面的方法
     return add(x, y);
}



int main() {
      test_add(5,6);
 ALOGE("test_addtest_addtest_addtest_addtest_addtest_add");
    return 0;

}

static_add.a 編譯好的靜態(tài)庫

• Android mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE    := static_add
LOCAL_SRC_FILES := libstatic_add.a
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE    := share_add
LOCAL_STATIC_LIBRARIES := static_add
LOCAL_SHARED_LIBRARIES := liblog
LOCAL_SRC_FILES := share.cpp
include $(BUILD_EXECUTABLE)

最后編譯，會(huì)在system/bin 下生成一個(gè)可執(zhí)行的二進(jìn)制文件share_add，拷貝到手機(jī)即可執(zhí)行測試
