This kind of speaks for itself...
Cannot complete the install because one or more required items could not be found.
Software being installed: Android Native Development Tools 20.0.0.v201206242043-391819 (com.android.ide.eclipse.ndk.feature.group 20.0.0.v201206242043-391819)
Missing requirement: Android Native Development Tools 20.0.0.v201206242043-391819 (com.android.ide.eclipse.ndk.feature.group 20.0.0.v201206242043-391819) requires 'org.eclipse.cdt.feature.group 0.0.0' but it could not be found
Did somebody else had the same problem ? Google tells me to install the plugin manually.
