Question

I have the following code:

 import android.support.v4.app.FragmentActivity;
 import android.support.v4.app.Fragment;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_exercises_list);


    List<Fragment> fList = new Vector<Fragment>();
    fList.add(Fragment.instantiate(this, "All"));

which is a fatal exception. If i remove line fList.add(Fragment.instantiate(this, "All"));, it’s fine. So what’s happening? I have no idea how to use fragments so I’m guessing my problem is a nooby one.

Answer 1

If your Fragment is a nested inner class, make sure you have declared it to be a public static class. Likewise, make sure the Fragment is named All.

That being said, I hope you know what you are doing, because I can’t imagine a scenario in which I would store a Vector of Fragments. At the very least you should use an ArrayList instead.

Also, you should post the exact error message you are getting, along with the rest of your logcat output.
