Answer 1

FragmentActivity is part of the v4 folder though right? v13 just means API 13 and above will use the classes in that folder. So while you may have that folder, I bet it doesn't have FragmentActivity in it :) Change your imports to have the v4 rather than the v13.

http://developer.android.com/reference/android/support/v4/app/FragmentActivity.html

So you know you can't use Fragment from the OS if you are using the SupportLib, you have to use only the Fragment classes inside the SupportLib. This include Fragment itself.

http://developer.android.com/reference/android/support/v4/app/Fragment.html vs http://developer.android.com/reference/android/app/Fragment.html.. Basically anything inside of android.app that has to do with Fragments, cannot be used with your SupportLib classes. They are not the same class hierarchy nor are they compatible.

Answer 2

This is the answer I gave to a very similar question:

Change the "import android.support.v13.app.FragmentActivity" to "import android.support.v4.app.FragmentActivity"

For the undefined part, try this syntax:

public class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
public ScreenSlidePagerAdapter (android.support.v4.app.FragmentManager fm) {
    super(fm);
}

and:

@Override
public android.support.v4.app.Fragment getItem(int position) {
    return ScreenSlidePagerAdapter.create(position);
}
