Default issues with fragment project
Hello, I have an issue that has me at a stand still. I have been working my way through the book, and I have gotten through the fragment project. I am on page 39 of the beginning android tablet application development. I have done all of the work through step 8 where it is time to run the app. I try to run the app, and everything loads, but the screen is just black where in the book it is green an yellow. I don't get any errors, in my code, and everything is running fine until I get a message in the emulator saying that "the application fragments has stopped unexpectedly", and then I click force close. any ideas? I am stumped. I have followed the instructions of the book, and am running windows 7. I have the most current versions of SDK, and Eclipse. I hope someone can hellp me out, because I am at a stand still until I figure this out. here is what I get in the LogCat after the failed load of Fragments.
