I downloaded the dropbox sdk zip off the dropbox website, then imported the program into eclispe. Then i configured the build path and added the 2.2 jar file to run, theres no errors until I load up the aplication, when I ran it on the 1.5 emulator it gave me a Uncaught handler: thread main exiting due to uncaught exception error, then when I ran it on the 2.2 emulator it gave me a at android.app.Instrumentation.newActivity(Instrumentation.java:1021) error its not even letting the ap run, any ideas?

  • Post some of the problematic code (where logcat claims the error is occuring) and possibly the logcat logs. – Gophermofur Apr 24 '12 at 16:02

That issue seems to come up when the library isn't properly loaded at runtime. I don't know much about it, but this question was asked and answered before. This may help: Gson NoClassDefFoundError after ADT and SDK Tools update to v17
