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:

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。
我刚刚发现的是，在更新构建工具之前，你需要更新Eclipse中的ADT插件(无论是独立的还是ADT Bundle)。
如果您的Eclipse安装指向最新的构建工具，并且您的Eclipse有ADT 22。X，它会显示这些误差。
对我有效的方法:(Ubuntu 14.04 64位)
安装旧版本的Eclipse和ADT(来自Bundle)
这个Eclipse副本指向一个使用旧构建工具的旧SDK版本(20年前)。
更新ADT到v23(通过存档，在我的情况下)
将Eclipse指向构建工具的最新版本。
您可能没有Eclipse和构建工具的旧版本，在这种情况下，您可以从SDK管理器卸载最新的构建工具，并安装旧版本。
一旦一切开始正常工作，执行上述步骤。
我试图在互联网上的某个地方上传这样的包的旧副本，将更新这里的链接，一旦我完成上传。
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;-(

在尝试了其他答案中的方法后没有成功，我只是从http://developer.android.com/sdk/installing/index.html?pkg=adt安装了一个新的捆绑包，效果很好。
做以下几点:
As you don't want to re-download all the platforms again, copy the existing one from /OLD_ANDROID_SDK_PATH/sdk/platforms to /NEW_ANDROID_SDK_PATH/sdk/platforms.
When opening the new Eclipse from the recent downloaded bundle, make sure you reuse the previous 'workspace' folder. That will ensure that all your previous settings will be remembered.
After opening the new Eclipse on the previous workspace, please check if the used Android SDK is pointing to the new one (Eclipse preferences -> Android). It might be pointing to the old one, as you've reused the previews workspace settings.
通过这些步骤，您不应该重新配置所有内容，也不需要花费时间从谷歌开发人员升级时排除此BUG。
好运！: -)
