8,334 PointsApp stopping on emulator before it even opens
I had a lot of problems getting my app to build. I put the code through an XML validator and ultimate added a closing </EditText> tag. I also tried adding the same final line that appears in the video, but that generated errors, and the closing EditText didn't. I got the project to build successfully, but now it's stopping on the emulator before it even gets started.

Also look at the code they have written and compare it with yours. Usually they have the zip file in the download section.

I had the same issue because my Story was creating Pages[] at index 1, not 0, and that would crash the app. If you could post your Java code, that would help.
Post your LogCat errors too :)

8,334 PointsI actually fixed this by downloading the project files and matching up the code. I think the problem was that I updated to a new version of Android Studio in the middle of the project, and it ended up mis-matching a couple of tags.
