Answer 1

I had a problem with identical symptoms and following solved it in my case.

1. If you're not already, use LogCat window to get more precise information about the exception than console offers.

2. If you haven't already, check through your layout XML files in case you have a custom object and you're using the wrong path for a resource.

3. If you haven't already, or you have to address the above, try cleaning your project and then building again.
