Android是作为智能手机的操作系统，我们开发的应用，大多数也都需要连接网络，通过网络发送数据、获取数据，因此作为一个应用开发者必须熟悉怎么进行网络访问与连接。通常android中进行网络连接一般是使用scoket或者http，http是最多的情况，这里，我来总结下，怎么进行http网络访问操作。 android是采用java语言进行开发的，android的包中包含java的URLConnection和apache 的httpclient，因此我们可以使用这两个工具进行网络连接和操作。同时，为了控制是否允许程序连接网络，我们开发应用时，需要在Manifest文件中配置申请网络连接的权限，代码如下。 <uses-permission android:name="android.permission.INTERNET"/> 使用URLConnection连接网络 URLConnection为java.net包中提供的网络访问，支持http，https，ftp等，进行http连接时，使用HttpURLConnection即可，示例代码如下： URL url = new URL("http://www.android.com/"); HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

电脑–推荐 Mac 　　首先声明我不是果粉，个人 Windows，Linux，Mac OX 系统均用过， 只能说 Windows 上面的开发工具简直难以恭维，尤其命令行超级难用，而 Linux 自己必须得花不少时间在折腾中，更是不适合新手了，Max OS 是我认为迄今为止最好用的系统，没有之一， 所以如果你不差钱的话，强烈建议入手一台 Mac，推荐 Pro 系列， 当然它的价格确实比较昂贵，如果暂时入手有困难，推荐以后手头宽裕的时候再入手吧，会带给你质的体验。(Google 的工程师们都在用 Mac，应该比较有说服力吧) 手机–推荐 Nexus 5 　　做 Android 开发最难以忍受的就是那龟速的模拟器，强烈推荐入手我 Google 的 Nexus 系列，原生 rom，性价比超高，有条件的推荐再入手一台小米或三星之类的，不是因为他们有多好用，而是因为目前市场上这两个品牌的手机份额最大，实际开发中可能需要 进行适配与测试，总之你需要有台 Android 手机。你可能还需要知道魅族手机有个 SmartBar 的东东，虽然我认为确实很 SB。最后你实在还是要用模拟器的话，那么姑且就给你推荐一款比较快速的模拟器吧—-Genymotion, 具体的见我这篇博客 一个强大的 Android 模拟器 Genymotion 开发环境 Eclipse ADT 　　Google
