推荐答案

如果您没有添加ADT然后执行以下步骤。

If you have not added ADT then do the Following steps.

帮助 - >添加新软件 - >添加

Help -> Add New Software -> Add.

在名称选项写ADT

如果你的电脑中已经安装了ADT再添加它的路径位置喜欢

And if you have installed ADT in your Computer then add its path in Location like

的jar：文件：/ D：/ADT-16.0.1.zip /

然后ADT将安装。

和，如果有一个问题尝试删除ADT并再次安装。

And if there is a problem try to remove that adt and install again.

1) remove the ADT repo (Window->Preferences->Install/Updates->Available Software Sites)
2) add Indigo repo ("http://download.eclipse.org/releases/indigo")
3) run updates
4) add ADT repo again and install
