ndk-build 这个命令有一些参数可以帮助我们编译，比如指定目录，指定Application.mk路径，指定android.mk路径,感觉除了android.mk文件，其他变量都可以指定： ndk-build NDK_PROJECT_PATH=.
NDK_APPLICATION_MK=Application.mk APP_BUILD_SCRIPT := $(LOCAL_PATH)/Android.mk

const char* pwd = "abcdefg";
result = sqlite3_open(path, &db);

if (result == SQLITE_OK)
    cout << "打开数据库成功" << endl;
else
    cout << "打开数据库失败" << endl;

result = sqlite3_key(db, pwd, strnlen(pwd, 1000));
cout << "指定数据库密码：" << result << endl;
