说是有重复，先卸载22.3.0版本ADT,如果在eclipse可以直接卸载就不用向下看了。
下面卸载先前版本，重新安装新版本ADT.
1. 删除adt-bundle-windows-x86-20131030\eclipse\plugins和features ADT相关文件夹和jar包
2. 删除adt-bundle-windows-x86-20131030\eclipse\configuration\org.eclipse.equinox.simpleconfigurator\bundles.info文件中关于adt的bundle.
3. 删除adt-bundle-windows-x86-20131030\eclipse\artifacts.xml中关于ADT相关节点.
4. 修改adt-bundle-windows-x86-20131030\eclipse\p2\org.eclipse.equinox.p2.engine\profileRegistry\profile.profile\1422350652305.profile.gz, 不一定是1422350652305.profile.gz，关健是最新一个。
这个文件保存所安装插件状态，不能直接删除了，删了就不能在界面安装插件了.
注意先关闭eclipse再修改最新的一个1422350652305.profile.gz, 解压修改后覆盖一下。eclipse安装历史中没有ADT了。
5. 修改adt-bundle-windows-x86-20131030\eclipse\configuration\config.ini不使用ADT图标和启动画面;
可以看到adt-bundle-windows-x86-20131030\eclipse\configuration\org.eclipse.equinox.simpleconfigurator中记录所有需要启动的bundle.
6. eclipse -clean启动eclipse, 这里eclipse就变成一个干净的eclipse了.
7. 重新安装ADT插件;
还是报错：

。。。。。。。。。。。
无语，放弃了，有时间再搞。
确实很麻繁啊！搞了一天这玩意，不过顺便也了解了一下eclipse架构，eclipse启动都先读取adt-bundle-windows-x86-20131030\eclipse\configuration\config.ini这个配置，里面配置了那些osgi的bundle需要启动。
再安装还是不能安装，需要修改adt-bundle-windows-x86-20131030\eclipse\p2\org.eclipse.equinox.p2.engine\profileRegistry\profile.profile\1422350652305.profile.gz这个配置才可以完全删除所有之前相关插件。
还是直接下载 adt-bundle-windows-x86-20140702.zip这个
这个可以直接更新5.0的SDK, 非官方下载地址：
