嗨，我是 eclipse 和 android 的新手。尝试在我的 Windows 7 笔记本电脑上设置 ADE。Eclipse 工作正常。现在我按照http://developer.android.com/sdk/installing/installing-adt.html上的程序进行操作
下载 ADT 插件
Start Eclipse, then select Help > Install New Software.
Click Add, in the top-right corner.
In the Add Repository dialog that appears, enter "ADT Plugin" for the Name and the following URL for the Location:
https://dl-ssl.google.com/android/eclipse/
Click OK.
到目前为止，一切都很好
If you have trouble acquiring the plugin, try using "http" in the Location URL, instead of "https" (https is preferred for security reasons).
In the Available Software dialog, select the checkbox next to Developer Tools and click Next.
In the next window, you'll see a list of the tools to be downloaded. Click Next.
Read and accept the license agreements, then click Finish.
If you get a security warning saying that the authenticity or validity of the software can't be established, click OK.
When the installation completes, restart Eclipse.
在这里我迷路了。当我重新启动 Eclipse 时，ADT 显然不存在，因为 File->New下拉菜单下没有Android App按钮。
谁能告诉我该怎么做才能让它工作？
