public class ThirdFragment extends AppCompatActivity { 
    Animation fade_in, fade_out;
    ViewFlipper viewFlipper;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_activity);
        viewFlipper = (ViewFlipper)  this.findViewById(R.id.bckgrndViewFlipper1);
        fade_in = AnimationUtils.loadAnimation(this,
                android.R.anim.fade_in);
        fade_out = AnimationUtils.loadAnimation(this,
                android.R.anim.fade_out);
        viewFlipper.setInAnimation(fade_in);
        viewFlipper.setOutAnimation(fade_out);

        viewFlipper.setAutoStart(true);
        viewFlipper.setFlipInterval(5000);
        viewFlipper.startFlipping();
    }

}

Java does not allow two classes in the same package to have the same name. What you should do is rename one of them. Another constraint is that more than one public class can only be declared in the same file if it is Inner class, i.e., if it is an "internal" class of the main public class. Since in your case it’s a class and an Internet class, it’ll work.

NOTE: It is also important to note that it does not make sense to give the same name to something that has different behaviors (Fragment and Appcompatactivity). That way, I suggest you review the purpose of each class to name them properly.
