我的ADT正确担任同不论在教程中所看到，直到当我创建了一个项目像以前一样，也是我选择2天前创建一个空白的活动，我希望它使一个默认的Hello World项目，我和一个主。 Java也一个XML布局文件，但它不会再创建这个默认的Hello World项目。我安装和更新的大部分东西在SDK管理器。我创造了另一个工作区，我做什么我可以，但它并没有创建默认的Hello World项目。但是当我从命令行创建项目时，它工作正常，并让一个Hello World项目。 ADT为什么不这样做呢？ 它在我的SDK管理器安装的软件包列表

My ADT worked correctly as same as whatever saw in tutorial until 2days ago when i created a project like before and also i selected "create a blank activity" and i expect it makes a default hello world project for me and a Main.java also a xml layout file, but it doesn't create this default hello world project anymore. i installed and updated Most of things in SDK Manager. i created another workspace and i did whatever i could but it doesn't create default hello world project. but when i create project from command line it works correctly and make a hello world project. why ADT doesn't do that? it's list of installed package on my SDK manager

和它在ADT项目树是空的，当我创建空白的活动项目：

and its the project tree in ADT that is empty when i create a project with blank activity:

但它在命令行。我使用相同的SDK管理器的命令行：

But it works in commandline. i use same sdk manager from command line:

~/Program/Andr/adt/sdk/tools $ ./android create project --target 24 --name MyFirstApp --path MyFirstApp --activity Main --package com.mrg.myfirstapp
Created project directory: MyFirstApp
....

和它使HelloWorld项目：

And it makes Helloworld project:
