android开源项目（一） AndroidSideMenu
SlidingMenu实现的效果如下：
最近直接拿来用！很火的android开源项目真的很牛，作为菜鸟我也要学习大神们的经验，牛顿曾说过：“如果说我看的远，那是因为站在巨人的肩膀上”
AndroidSideMenu的来源是github 代码库中的开源项目：路径如下：git://github.com/dmitry-zaitsev/AndroidSideMenu.git
那么怎样把github代码仓库中的项目导入到我们常用的Eclipse中呢？详细步骤请看下面：
1.首先安装EGit插件，如果已有可以略过。
在eclipse的help中选择Eclipse Marketplace 在find中输入egit就会出现如下界面
点击install， 等待安装完毕
然后接受安装协议
然后eclipse就开始安装EGit
片刻后，EGit就可以安装好了，
2.克隆Git仓库上的代码到本地电脑，并在Eclipse中查看Git中的工程
1.步骤如下：file—Import---Git--ProjectFromGit--URI
2.从git://github.com/dmitry-zaitsev/AndroidSideMenu.git 地址中clone androidslidingMenu项目，
默认next 后出现以下，
继续默认next，选择克隆代码存放的位置
clon完毕后会出现以下选择界面
这样就可以导入从Git上下载的工程了
在eclipse中的布局如下
当我们导入从Git中下载好后的东西，我们却发现运行不了，我在网上也收了很多方法，可惜可有收到怎样解决的方法，如果谁有好的方法可以给我说说，
我的解决方法如下：
3.创建android工程
新建一个android工程，然后将布局，实现的代码等复制进去，修改修改最后终于给弄好了，不过呢，这个android工程要求建立的版本的在android 3.0之上的才可以运行，我试着建立常用的2.3.3 或则3.0以下的版本，结果发现有点不兼容...不知道那些牛逼的应用中怎样解决这个兼容性的问题的...
