Cannot complete the install because one or more required items could not be found.
Software being installed: Android Development Tools 21.0.0.v201210310015-519525 (com.android.ide.eclipse.adt.feature.group 21.0.0.v201210310015-519525)
Missing requirement: Android Development Tools 21.0.0.v201210310015-519525 (com.android.ide.eclipse.adt.feature.group 21.0.0.v201210310015-519525) requires 'org.eclipse.ui 3.6.0' but it could not be found！！

------解决方案--------------------
你的ADT不支持最新的SDK，建议把SDK的版本弄底，否则升级你的ADT.
------解决方案--------------------
ADT版本低了下个ADT-21.0.0.zip
或者直接更新Help-Install New Software..-what is already installed-选中要更新的再点下面的Update
------解决方案--------------------
楼上说法是对的哦
