Some things are different now

Hello, I think that some things are different from this video but there is no a problem. There is a new class called PlaceholderFragment that makes the things more easily and the public Fragment getItem(int position) method in the SectionsPagerAdapter class have only one line of code now.

The PlaceholderFragment class was in the MainActivity class just like SectionsPagerAdapter class. I extracted this class in the same way that was made in this video. But this time when you organize imports, you will have two options to choose from. v4 support and v13 support libraries.

Thanks for the heads up! I've started the process of refreshing my courses because of these types of differences. I'm about to publish a new version of Build a Simple Android App and will hopefully get to this course before too long. Let us know here in the Forum if you come across any differences that keep you from progressing.
