I created draw9patch image and its working fine in my machine.
I uploaded to accurev(like SVN) my colleague downloaded the workspace and he installed in 10′ inch device and we noticed that the image is not showing fine.
It looks like normal image with stretched.
what happened to my draw9patch image? the file name is showing as xxx.9.png.
when we download from server will draw9patch image will get change?
//this is my 9 patch image

It is not likely that your image changed when you pulled it from your repository. It is more likely that the image you’ve created simply does not stretch very well on a 10″ device.
Did you include one image for each screen density?
