Error :
When I try to install the Android Developer Tool, I get the following error.
Software being installed: Android Development Tools 11.0.0.v201105251008-128486 (com.android.ide.eclipse.adt.feature.group 11.0.0.v201105251008-128486) Missing requirement: Android Development Tools 11.0.0.v201105251008-128486 (com.android.ide.eclipse.adt.feature.group 11.0.0.v201105251008-128486) requires 'org.eclipse.wst.sse.core 0.0.0' but it could not be found
