Trying to add a fragment to my fragment container FrameLayout

Question

I have created an xml file called editor.xml which contains a FrameLayout. In my main activity I am trying to add my custom fragment to my FrameLayout.

The error I receive when trying to add my fragment is:

The method add(int, Fragment) in the type FragmentTransaction is not applicable for the arguments (int, editorFrag)

However my editorFrag extends Fragment so I am confused on why this is happening. Below is my code for the files I have mentioned. Any help is appreciated.

Editor.xml

<?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/fragment_container" android:layout_width="match_parent" android:layout_height="match_parent" /> 

editorFrag.java

public class editorFrag extends Fragment {     @Override     public View onCreateView(LayoutInflater inflater, ViewGroup container,          Bundle savedInstanceState)      {          // Inflate the layout for this fragment         return inflater.inflate(R.layout.newlevel, container, false);     } } 

MainActivity.java

public class editorActivity extends FragmentActivity {     @Override     public void onCreate(Bundle savedInstanceState)      {         super.onCreate(savedInstanceState);          setContentView(R.layout.editor);          // Check that the activity is using the layout version with the fragment_container FrameLayout         if(findViewById(R.id.fragment_container) != null)         {             // if we are being restored from a previous state, then we dont need to do anything and should             // return or else we could end up with overlapping fragments.             if(savedInstanceState != null)                 return;              // Create an instance of editorFrag             editorFrag firstFrag = new editorFrag();              // add fragment to the fragment container layout             getSupportFragmentManager().beginTransaction().add(R.id.fragment_container, firstFrag);         }     }  }

Luksprog answered this problem for me below by telling me to check my imports. Eclipse chose to import the SDK version of Fragment instead of the support version that I needed. Thank you for the help.

You forgot to commit() your transaction.
