App crashes with exception before Activity.onCreate() Java android

Question

I get this weird exception:

libcore.io.ErrnoException: access failed: ENOENT (No such file or directory)

All I did was that I modified res/layout/main_activity.xml

But when I roll back to the previous situation, I get same exception. I know this looks like the problem is elsewhere, but I just can't figure where. Any hints, please ?

Here is part of the back trace in the relevant thread: This is an export of back trace of the main thread. Problem is in the top most line.

In cases like this, you save your time and sanity by rolling back to previous version and start over. Even better - use another IDE than Eclipse. That's exactly what I did and it helped in full sence.
