使用android SDK的Eclipse中的Android Application NFC错误

Question

I am working on an android application in eclipse with the android SDK and I keep getting these errors that I cannot understand(This is my first application for android) and these errors may stem from either my lack of coding skills or the setup in the XML file, so I hate to flood you, the reader, with all of this but here goes, Output:

        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

}

Sorry it is all quite ugly, I am pretty sure my code is quite wrong in most of it, but that isn't the piece I care about, feel free to help on that but really what I need to know is why these errors are happening and how to fix them. Sorry this is a massive post. Thanks.

Answer 1

The line in your trace

android.content.res.Resources$NotFoundException: Resource is not a Drawable (color or path): TypedValue{t=0x1/d=0x7f060000 a=-1 r=0x7f060000}

suggests that you are trying to point to an undefined resource (Color/Path) in one of your layout files.
