As far as I can tell, the current release of the Android SDK (R08) ships without the Swing Desktop jar, and this causes draw9patch to fail.

[2]+ Done draw9patch
The ‘fix’ is rather simple: just download the JAR for Swing Desktop from here, and drop the swinglabs-0.8.0.jar file into the [sdk-install-dir]/tools/lib folder.The Swing Desktop project can be found here.
Update — Richard just left a comment here and pointed me to his site (Android 9 Patch) who’s got plenty of 9-patch icons that really look awesome, and I thought I’d share the goodness (especially, given he’s so kind as to share them at no charge).
Go check out Patch 15, it’s pretty impressive!

Thanks Marco!!! 🙂 Life saver (though I didn't use it in the end but I hate to see things break for no reason).Hope you don't mind, I posted your solution to another guy suffering from the same pain .

Hey Richard — that's really cool stuff!I'll update my post later to point the main text to your site (and, I can already see I'll use some of your stuff on my Android Receipts LoL https://sites.google.com/site/androidreceipts/ )Thanks for sharing!
Great Marco!Glad it's coming to be used.I'll have more 9-patch sometime this weekend.Writting the app was taking too much of my time 🙂
Marco,There are now 500+ free 9-patch images ready!!!I have finally managed to complete the android browser you can find here: http://market.android.com/details?id=com.android9patch.viewerMore to come soon!Cheers!
In case people bang their heads on why 9-patches don't work, I found out that they all need to be in one directory drawable-xhdpi. Even if there are other .9.png files that you don't use at all, in any other directory, they won't work.
