I have recently updated my app to a build tarket of SDK version 8 in order to include the App2SD feature for my users.

However I have had reports of devices on SDK 3 (1.5) having problems starting the application, with the following stack trace:

...

If i change the build target back to version 4 as it was previously this issue goes away, also if i remove any graphical resources from my XML files this issue goes away!

Any help would be much appreciated as i currently have a broken app on the market for many users.
