Most of the examples talk about creating a 9-patch image, but implementation details are usually left at a high level.

Nick's post above - with the good 9-patch tutorial that provides a working project download file , saved the day.

Here are the main implementation details that worked for me (once you have a 9-patch image ready to go):

1. Reference the drawable with the name but don't include .9.png (auto-complete in eclipse will take care of this)

2. Make sure you only have 1 image under the main /drawable folder (not a version for each dpi folder)

3. The image must be specified using :background, not :src (this got me stuck for a while)

   android:background="@drawable/splash_logo"

4. Make sure the image and layout that contains it are using:

   android:layout_width="fill_parent"
android:layout_height="fill_parent"
