ADT will not allow creation of Android Activity
提问by NewShelbyWoo
I installed the ADT bundle from http://developer.android.com/sdk/index.htmlyesterday, and I was following a basic Hello World tutorial. I created a new Android Application Project with a Blank Activity named MainActivity. The resulting project has an empty srcfolder and empty res\layoutfolder. There is a R.javafile in the genfolder but it has no reference to MainActivity. This is what the SDK manager says I have installed
我昨天从http://developer.android.com/sdk/index.html安装了 ADT 包，我正在学习基本的 Hello World 教程。我创建了一个新的 Android 应用程序项目，其中包含一个名为MainActivity. 生成的项目有一个空src文件夹和一个空文件res\layout夹。R.java文件gen夹中有一个文件，但它没有引用MainActivity. 这就是 SDK 管理器所说的我已经安装
- Android SDK Tools v 22.6
- Android SDK Platform-tools v 19.0.1
- Android SDK Build-tools v 19
- SDK Platform v 3
- ARM EABI v7a System Image v 2
- Android Support Library v 19.0.1
- Google USB Driver v 9
- Android SDK 工具 v 22.6
- Android SDK 平台工具 v 19.0.1
- Android SDK 构建工具 v 19
- SDK 平台 v 3
- ARM EABI v7a 系统映像 v 2
- Android 支持库 v 19.0.1
- 谷歌 USB 驱动程序 v 9
I also tried manually creating an activity by right clicking the srcfolder and going to Android Activity, but when I hit Finish on the creation wizard, nothing happens. Does anyone have any clues as to what's going on? Did I miss a key component to install or something?
我还尝试通过右键单击src文件夹并转到 Android 活动来手动创建活动，但是当我在创建向导上点击完成时，没有任何反应。有没有人知道发生了什么？我是否错过了要安装的关键组件或其他什么？

If you updated to Android SDK Tools version 22.6, you are required to Update DDMS Tools and Plugins.
如果您更新到 Android SDK 工具版本 22.6，则需要更新 DDMS 工具和插件。
Go to "Help Menu Bar" -> "Install New software" and install (this will update it) url: https://dl-ssl.google.com/android/eclipse/
转到“帮助菜单栏”->“安装新软件”并安装（这将更新它）网址：https: //dl-ssl.google.com/android/eclipse/
Also update "Developer Tools"and "NDK Plugins"to latest Version. This steps is useful for me and worked also.
还将“开发人员工具”和“NDK 插件”更新到最新版本。这些步骤对我有用并且也有效。

workspace has to be set to the the SDK folder. After doing this, I have had no problems. For example, after downloading and installing Eclipse, my directory structure is as follows:
工作区必须设置为 SDK 文件夹。这样做之后，我没有任何问题。比如下载安装Eclipse后，我的目录结构如下：
/Users/username/Development/adt-bundle-mac-x86_64-20140702/
/eclipse/
/sdk/
/HelloWorld/
It's annoying because the default workspace was set as documents/workspace(changing permissions with chmod 777 workspace didn't work in my case. Plus it's inconvenient that all my projects are mixed in with other folders in the SDK folder.
这很烦人，因为默认工作区设置为documents/workspace（使用 chmod 777 工作区更改权限在我的情况下不起作用。另外，我的所有项目都与 SDK 文件夹中的其他文件夹混合在一起很不方便。
