Why is my app trying to use drawable-mdpi/title_bar_shadow.9.png?

The app works fine on HPDI and MDPI, but when run in an LDPI (v2.0) emulator, I get the exception and stack trace below.

Why is it looking for this image? (it's not referenced in my application, I've checked). The starter activity has disabled the title bar in any case.

If the OS expects this image, why is it not present?

Why is the exception relating to an MPDI image, when the emulator is LDPI?

If the OS expects this image, why is it not present?

Why is the exception relating to an MPDI image, when the emulator is LDPI?

If the requested resource (title_bar_shadow.9.png) is not present in drawable-ldpi (and it wasn't until Android 2.3), Android will try to find the best match (drawable-mdpi will be the next folder to search in). Anyway, the file will not be found there either (again, it was not there until Android 2.3). So the next step would be to search for it in drawable-hdpi (where it can be found). But apparently the search stops on drawable-mdpi (which is strange... maybe a bug in Android 2.1? you could try Android 2.2 emulator)

Why is it looking for this image? (it's not referenced in my application, I've checked). The starter activity has disabled the title bar in any case.

This image (shadow) is not used by the title bar. It is displayed UNDER the title bar. To make it disappear, you have to create your own theme, like this:

<style
  name="Theme"
  parent="android:Theme.NoTitleBar">
  <item
    name="android:windowContentOverlay">@null</item>
</style>

I solved this problem making a copy of the images from drawable-ldpi/mdip/hdpi to a drawable (only drawable) folder. Put in this folder your low resolution images.

You don't need to have a title_bar_shadow.9.png file on these folders.
