我用新的SDK工具更新了Eclipse (rev. 23)，但现在当Eclipse启动时，我收到了错误:
此Android SDK要求Android Developer Toolkit版本23.0.0或以上。当前版本为22.6.3.v201404151837-1123206。请更新ADT到最新版本
“检查更新”没有发现更新。如果我尝试“安装新软件”，我可以看到版本23，但由于以下错误，我无法升级:
Cannot complete the install because of a conflicting dependency.

从网站下载上一份ADT后，似乎又出现了一个问题。
没有安装SDK Tools rev. 23 proguard，文件夹SDK dir/ Tools /proguard丢失，其他工具也丢失。这个版本包含几个错误。
下载ADT的完整过程，在Eclipse中配置它，并修复依赖关系问题:
下载ADT:
打开这个链接:https://dl-ssl.google.com/android/eclipse/
下载最新版本的ADT-23.0.2.zip到ZIP文件夹中，不要解压缩。
在Eclipse中配置ADT:
打开Eclipse→进入菜单帮助→安装新软件…
点击添加..按钮在右边。
将打开Add Repository对话框。
在“名称”中:写入ADT Plugin
在位置:输入你下载的ADT压缩文件夹的路径，点击存档。按钮。
**错误可能是重复位置。要解决这个问题，请遵循以下步骤:
1.1关闭当前对话框。
1.2单击Available software sites链接，选择与您添加压缩文件或ADT Plugin条目位置相同的条目。选择后，删除它。
1.3再次进入前面的Add…对话框。
1.4再次在“添加存储库”对话框中添加“名称”和“位置”。
在“开发工具”中选择所有选项，然后单击“下一步”以完全安装ADT。
修复ADT中的依赖问题:在以上所有步骤之后，依赖问题可能会出现。要解决这个问题，请遵循以下步骤:
在“安装”对话框中单击“已安装”。
单击Installed Software选项卡，现在选择所有以前版本的开发工具，并卸载它们。
现在所有的依赖问题都将消失，并遵循Next, Next向导安装:)
愿一切都好！这肯定会有帮助。
我遵循了这里找到的说明，并试图修复我的旧Eclipse + SDK + ADT，但没有运气。基本问题是一样的;我仍然得到错误消息:
此Android SDK要求Android Developer Toolkit版本23.0.0或以上。当前版本为22.6.3.v201404151837-1123206。请更新ADT到最新版本
但是我的eclipse找不到更新，也不能将ADT 23作为新软件安装。所以我不能在我的工作区编译我的旧项目。
I tested a fresh eclipode bundle for Windows 8, followed instructions found from Android's developers page, step by step, and it worked fine. So it seems that the Windows Eclipse build is not broken. But I wan't use my Linux installation, my old Ubuntu 10. It seems obvious, that to getting the Linux Eclipse environment working again, I must install a new Eclipse bundle, my old Eclipse won't ever see updates for ADT 23 to get things working. Again, these intructions are for Linux developers that wan't to get their old workspace projects working again without changes in the developing environment, except you must install a new Eclipse bundle, but after that your projects will work as well as before the version 23 SDK/ADT-mess.
If you are an Android developer you want to be sure, that you developing environment won't be messed up. Backup:
~./android (Here are your developer keys)
Your old SDK dirrectory
Your workspace
Download the Eclipse bundle, Get the Android SDK.
Follow instructions, create directory ~/Development and unzip bundle there. You get Eclipse and SDK directories.
Start Eclipse from that directory
Eclipse asks for a workspace. You can give it the old one.
In Eclipse settings set SDK as downloaded SDK.
Start Android SDK manager and download tools, Android versions you use and extras said in the Android developer tool page instructions
You should now be ready to compile your old projects again, but for me it was not that simple. My old projects had errors. So open problems windows and you get to know that annotation.jar is missing. So you must copy annotations.jar from your old SDK, from, the backup you made, or from the older sdk.zip explained in this thread to <new SDK>/tools/support/annotations.jar
在那之后，我可以使用我在Ubuntu中的旧工作区，并在Android设备上编译和启动应用程序。就是这么简单。谢谢谷歌;-(
