Hi Guys,

I have an application which is based Android 1.5 but for enabling different
screen types support I have to compile and package it with v1.6. When I
install and run the resulted APK on my 1.5 emulator, everything works fine
except that "Preferences" activity crashes every time I launch it!

When I revert back my API dependency to 1.5 and remove a few 1.6 specific
config blocks from AndroidManifest.xml and compile/package it with 1.5,
everything works just fine!!

Below is the exception I get when it crashes. I will highly appreciate any
help on this:
