Hi, I have developed an application which has several packages within it's project... A class in one of those packages is called right away in the first line of code, which throws the dreaded java.lang.NoClassDefFoundError error... I don't get it, the package simply is within the project, and it works fine on my Android 1.6 device, but won't work with my 1.5 device... I do have to say that the project was originally set for 1.6, but then I changed the within the manifest from 4 to 3... Is that bad practice ? Or maybe it has nothing to do with the platform version ?

Also I do get these lines as wel from the DDMS :

05-04 17:24:59.921: WARN/dalvikvm(2041): VFY: unable to resolve static field 2 (MANUFACTURER) in Landroid/os/Build;

Thats the ManagementModule which also tries to retrieve several info-fields of the device itself... Again, this works just fine on the 1.6 device, even though thats a development device whilst my 1.5 device is a non-development device...
