Why does eclipse give me errors when i try to run sample application?

I dont know why the sample application from the android website gives me 300+ errors when i try to run it in ecplise galileo. The application i am trying is Bluetoothchat it is straight from the sdk sample folder so it shouldn't contain any. I have added android.jar and I do have an emulator. I have tried HelloWorld and it wo开发者_开发知识库rked..Could someone help me? Thanks

As far as I know the emulator doesn't support Bluetooth (See this question). Still the application should run and report that Bluetooth isn't available. Which API are you using? Also, do you get compile or runtime errors?
