Android NDK的C++11标准支持

标签：c++11   ndk   android   

C++11在Android NDK中已经支持了，本文主要介绍如何在NDK中添加C++11标准的支持。

在开源项目Cocos2d-x中，已经添加了C++11标准的支持。

1.修改Application.mk文件，添加NDK_TOOLCHAIN_VERSION

NDK_TOOLCHAIN_VERSION=4.8

APP_CPPFLAGS := -frtti -std=c++11 

#include <android/log.h>

#include <vector>
#include <initializer_list>
using namespace::std;

#define  LOG_TAG    "cachetest"
#define  LOGI(...)  __android_log_print(ANDROID_LOG_INFO,LOG_TAG,__VA_ARGS__)

template <typename T>
class MyArray
{
private:
    vector<T> m_Array;
 
public:
    MyArray() { }
 
    MyArray(const initializer_list<T>& il)
    {
        // Manually populate the elements of the array from initializer_list x
        for (auto x: il){ // use range-based for statement to iterate over the elements of the initializer list
            m_Array.push_back(x); // push them into the array manually
		}
	}
	
	void showContent()
	{
		//old way
		LOGI("in old way");
		for (std::vector<int>::iterator itr = m_Array.begin(); itr != m_Array.end(); ++itr){
			LOGI("%d",(*itr));
		}
		
		LOGI("in c++11 new way");
		for (auto x: m_Array){ //x is readonly
			LOGI("%d",x);
		}
	}
};


void test_cpp_new_version_11()
{
	auto x = 1;//int x = 1;
	int *p = nullptr;//int *p = NULL;
	MyArray<int> foo = { 3, 4, 6, 9 };
	foo.showContent();
}
