Question: Here is the code I have. I'm getting a red line under `new MainFragment();` with the error `Type mismatch: cannot convert from WishlistFragment to Fragment`:

```
Fragment newfragment = new MainFragment();   

```

Here is what my MainFragment.java file looks like:

```
public class MainFragment extends Fragment {
    public MainFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
        return inflater.inflate(R.layout.fragment_main, container, false);
    }
}

```

Any ides on why this is happening? I have a feeling it's something stupid I am looking over and I am just code-blind right now from a long day.

Answer: 
Make sure that both places are importing the same `Fragment` class. It feels a bit like in one place you are importing `android.app.Fragment` (the native API Level 11 version of fragments) and in the other places you are importing `android.support.v4.app.Fragment` (the fragments from the Android Support package).
Figured out the issue.... my MainActivity.java file was using:

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

```

and my MainFragment.java file was using:

```
import android.app.Fragment;

```

So there was a mismatch. I am using ICS 4.0 and higher as my lowest API version. Changing everything to import to the v4 API solved my issue.
