1. 什么是Volley
在这之前，我们在程序中需要和网络通信的时候，大体使用的东西莫过于AsyncTaskLoader，HttpURLConnection，AsyncTask，HTTPClient（Apache）等，今年的Google I/O 2013上，Volley发布了。Volley是Android平台上的网络通信库，能使网络通信更快，更简单，更健壮。
这是Volley名称的由来： a burst or emission of many things or a large amount at once

2.Afinal是一个android的ioc，orm框架，内置了四大模块功能：FinalAcitivity,FinalBitmap,FinalDb,FinalHttp。
通过finalActivity，我们可以通过注解的方式进行绑定ui和事件。通过finalBitmap，我们可以方便的加载bitmap图片，而无需考虑oom等问题

其中volly下载
git clone https://android.googlesource.com/platform/frameworks/volley
按照上面的方法，下载时，可能报连接超时，这是因为，android源码，默认下载是用匿名方式的，google为了某种性能和管理目的，做了限制，像一 般的，动态公网IP就 可能下载不了。为此，google提供了认证方式下载。
Using authentication
By default, access to the Android source code is anonymous. To protect the servers against excessive usage, each IP address is associated with a quota.
When sharing an IP address with other users (e.g. when accessing the source repositories from beyond a NAT firewall), the quotas can trigger even for regular usage patterns (e.g. if many users sync new clients from the same IP address within a short period).
In that case, it is possible to use authenticated access, which then uses a separate quota for each user, regardless of the IP address.
The first step is to create a password from the password generator and to save it in ~/.netrc according to the instructions on that page.
The second step is to force authenticated access, by using the following manifest URI:https://android.googlesource.com/a/platform/frameworks/volley. Notice how the /a/ directory prefix triggers mandatory authentication. You can convert an existing client to use mandatory authentication with the following command:
在windows xp中配置环境变量
配置_netrc文件，内容为在google生成的账号与密码
