问题
Somehow I just pressed some key or key combination in eclipse (android development) and eclipse suddenly restored the previous version of the file I was working on. CTRL Z/Y does not help. Do I have to do all my changes to the file again!??
And WHAT could I have just done? I don't want that to happen anymore. How could I possible continue working with eclipse knowing this could happen again sometime.
Thanks,

I think I had the same problem and figured it out after a few minutes.
Eclipse keeps a local version history and it is somehow possible with a wrong click or the wrong key-press to revert back to a previous version I am not sure what caused it.
To fix it right-click on the file name and then go down to "Replace With"->"Previous from Local History" you should now be able to find the correct version and get back your lost work.
