After failing to make GCM work (see one of many 'GooglePlayServicesUtil class not found' questions), desparately I tried to follow one advice which was to reinstall ADT. After doing so now nothing is working: SDK path was wrong (fixed), previous AVDs are broken, I can't create new AVD since the OK button is disabled, 'Check for updates' declares that there are no updaes but yet pops-up an error dialog saying: "Unable to read repository at http://download.eclipse.org/releases/juno. Unable to read repository at file:/C:/Program Files/adt-bundle-windows-x86_64-20140702/eclipse/p2/org.eclipse.equinox.p2.repository/cache/content-117422482.jar. Premature end of file."
I assume that the best option for me now is to completely remove eclipse and ADT and start afresh. What should I do to accomplish it? Previously I only removed the adt-bundle dir and apprently this was not enough.
Yep, at this point you are better off uninstalling ADT and resintalling it.
You have to remove the adt-bundle and delete the
C:\Users\mpascual\.android
folder. Then, install again.pd: don't forget to replace "mpascual" with your username :P
