Android framework中使用stl库

来源：互联网发布：大学毕业后悔做程序员编辑：程序博客网时间：2024/06/04 19:33

在Android的framework或者ndk中使用stl库中的方法，如std::string 时需要修改Android.mk文件添加相应的库支持。

主要步骤如下:

LOCAL_SHARED_LIBRARIES中添加libstlport；

LOCAL_C_INCLUDES中添加 external/stlport/stlport bionic bionic/libc/private

如下为本文修改的方法：

使用demo

在cpp中使用std标准库中的string类时需要注意如下步骤：

1.导入头文件

#include <string>

2.添加类的引用命名空间

using namespace std;
