Answer 1

I got this error when I added an image I had saved in gimp as 'filename.9.png' (which I thought was enough to produce a 9-patch image) to the drawable folder. To solve the issue I just opened the image in the Draw 9-patch tool and moved one of the bounds around - it didn't seem to matter whether I moved it back to the same spot, just the act of moving the bounds seems to correct the issue.
