Everytime I start the debugger, before my app even starts or installs, the 
debugger stops on an exception:

libcore.io.ErrnoException.

I have no idea what this means. I did a search, but other people who have 
gotten a similar error seem to be doing something wrong with loading files. 
My code has no file processing, but more importantly, my app hasn't even 
started! 

I did a search in the LogCat, but there is nothing about ErrnoException. 
These are some of the error messages I catch instead:

I tried uninstalling and updating Intellij, thinking it was an IDE. No 
luck. I updated all the SDK APIs I had installed. No luck.

The only code I added before this started happening was adding a Preference 
activity. 
Even when I roll back changes on git, I still get the same error.

What the hell is going on? Why is my debugger catching this error, and why 
now? What part of the toolchain is messed up? I'm not sure what is messed 
up....my 
code, ide, SDK, or emulator?
