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。
谷歌发布了ADT v23.0.2。这解决了之前ADT版本23的许多问题。
循序渐进:
菜单帮助→安装新软件…
对于“Work with”，选择Android源代码https://dl-ssl.google.com/android/eclipse
勾选ADT v23.0进行安装，然后点击“下一步”
Eclipse将显示“安装修复页面”，因为与以前的版本有冲突。(如果没有，请参见下文。)选择“更新我的安装使其与正在安装的项目兼容”以卸载旧版本并安装新版本。之后，按照通常的步骤进行。
注意:当我安装新版本的ADT时，我没有包括新版本的“Android原生开发工具”包。相反，我先安装了其余的包，然后安装了“Android原生开发工具”。由于某种原因，如果我尝试安装包括“Android原生开发工具”在内的所有新包，安装会失败。
如果没有“补救页面”，从Eclipse中删除ADT插件的唯一方法是进入菜单帮助→关于Eclipse→安装详细信息并从那里卸载。但是存在卸载Eclipse本身的风险。
我已经做了以下来解决一个问题。
Go to http://developer.android.com/sdk/installing/installing-adt.html and download the latest ADT ZIP file (at the bottom of page).
Go to Eclipse → menu Help → About Eclipse → Installation details
Delete Android DDM, Android Development Tools, Hierarchy Viewer, Native Development Tools, TraceView, etc., 22.X version.
Menu Help* → Install New Software → Add → Archive → *Select the downloaded ZIP file in step 1.
Select all the latest version of all 23 which I have deleted in step 3 and accept the license agreement.
重新启动Eclipse，它就修复了我的问题。
如何从22.xx更新。X到23.0.2(我的解决方案)。这将解决依赖性问题。
我被这个问题折磨了几天，我已经尝试了这个环节上的每一个解决方案，但运气不好。我终于想出了一个真正有效的解决方案!
请注意，此解决方案适用于Windows 7(64位)。它应该适用于其他Windows操作系统。
开始吧:
download the latest ADT bundle from
http://developer.android.com/sdk/index.html#download
unzip it and open "eclipse" folder --> "plugins" folder
Now go to your old eclipse and open "eclipse" folder --> "plugins" folder, and copy everything inside.
Now paste them into the "plugins" folder of the (NEW ECLIPSE), but DO NOT overwrite anything.
While inside of the "plugins" folder of your new Eclipse, do the search. Type in 22. (notice 22 with a dot) and hit enter.
The search result will show up all the files or folders with .....22.6...... For example,
com.android.ide.eclipse.adt_**22.6.2**.v201403212031-1085508
Highlight all of these files/folders and hit delete key.
Make sure to update your old API/SDK to the latest version and load this sdk directory to work with your new eclipse.
or
您可以观看这个视频，它向您展示如何将所有SDK/API移动到新的SDK文件夹。

我没有尝试从任何其他ADT版本更新，但我认为它应该适用于任何旧的ADT版本。
尝试之前不要忘记备份。
