Platform-tools version 14 has this problem, but not version 13.
Platform-tools 版本 14 有这个问题，但版本 13 没有。
http://dl-ssl.google.com/android/repository/platform-tools_r13-linux.zip
http://dl-ssl.google.com/android/repository/platform-tools_r13-linux.zip
I backed up my current (problematic) /android-sdk/platform tools, deleted the old folder and replaced it with ver 13, started eclipse, reset the android-sdk path (windows>preferences>android, don't forget to click "apply") and recreated my AVD.
我备份了我当前的（有问题的）/android-sdk/platform 工具，删除了旧文件夹并将其替换为 ver 13，启动 eclipse，重置 android-sdk 路径（windows>preferences>android，不要忘记点击“ apply") 并重新创建了我的 AVD。
Version 13 also has the heirarchical parent text box, but it's optional.
版本 13 也有分层父文本框，但它是可选的。

The problem is a bug with the Application Wizard... which triesto integrate the Activity Wizard within itself. The problem is that the integrated Activity Wizard doesn't work correctly without there being an existing project.
问题是应用程序向导的一个错误...它试图将活动向导集成到自身中。问题是集成的活动向导在没有现有项目的情况下无法正常工作。
Therefore, an easy solution to this problem is from the Project Wizard, just create a basic main activity with "none" for navigation type and click "finish". Then once the project has been created, use the Activity Wizard to create your desired main Activity.
因此，这个问题的一个简单解决方案是从项目向导中，只需创建一个导航类型为“无”的基本主要活动，然后单击“完成”。然后，一旦创建了项目，就可以使用活动向导创建所需的主活动。
As a bonus, the Activity Wizard will even refactor the code to use this new Activity as your main Activity!
作为奖励，活动向导甚至会重构代码以使用这个新活动作为您的主要活动！

1.Copy your Package Name, then past to "Hierarchical Parent" Field. (any words to skip this step)
1.复制您的包名称，然后粘贴到“Hierarchical Parent”字段。（任何话跳过这一步）
2.AndroidManifest.xml need an "android.intent.action.MAIN" for start. Add follow source code
2.AndroidManifest.xml 需要一个“android.intent.action.MAIN”来启动。添加关注源代码
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
like this：
像这样：
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
