I have created a simple 9 patch for an android EditText background. It works exactly as expected when I preview the graphical layout in eclipse.
The problem is that when I install the app on the device, the said EditText is horribly scaled, almost indistinguishable.
What could be the problem?
It probably has garbage (pixels not exactly black) on the 9-patch area (1 pixel border) and hence it doesn't understand it as a 9-patch.
Save this image with the draw9patch tool and clean your project before building it!
