My app works on 1.5 emulator and 1.5 device. When i try to start it on 1.6 emulator, it produces strange exceptions (doesn't even start). I don't have any 1.6 device to try this app if it works on a real device.
I get some warnings in Eclipse ( warning: Ignoring InnerClasses attribute for an anonymous inner class that doesn't come with an associated EnclosingMethod attribute. This class was probably produced by a broken compiler.) and get cant rid of them (i think they come from some apache jars that i need to make http multipart posts).
 Is it possible that this jars are cause for my exceptions in 1.6 or is it something else?

My logacat:
