Fetching user group from facebook using facebook api

Question

I want to fetch the user groups and want to list them but I am unable to fetch the groups from Facebook, though I am able to do

*Successful Login
*fetch friend list 
*i have also allowed the permission user_groups for fetching user groups

here I am doing like this for fetching user group

AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
mAsyncRunner.request("me/groups", params,
                    new GroupsRequestListener());

public class GroupsRequestListener extends BaseRequestListener {

    @Override
    public void onComplete(final String response, final Object state) {
        dialog.cancel();
        Log.v("response", response);
        Intent myIntent = new Intent(getApplicationContext(),
                GroupsList.class);
        myIntent.putExtra("API_RESPONSE", response);
        startActivity(myIntent);
    }

    public void onFacebookError(FacebookError error) {
        dialog.cancel();

        Toast.makeText(getApplicationContext(),
                "Facebook Error: " + error.getMessage(), Toast.LENGTH_SHORT)
                .show();
    }

}

But I got a response, something like this on log

06-15 07:43:19.563: V/response(645): {"error":{"message":"(#100) Unknown fields:    location,birthday","type":"OAuthException","code":100}}

"me/friends" parameters is ok for fetching friend list. Is the parameter "me/groups" right for fetching user group?

Thanks @Christoph Eberhardt. i got the solution with your help. what i was doing mistake is the worng request parameters. the params should be

Bundle params = new Bundle();
params.putString("fields", "name");

after setting request params,above code works perfectly. The complete solution for fetching user group is

//onCreate
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
Bundle params = new Bundle();
params.putString("fields", "name");

mAsyncRunner.request("me/groups", params,
                new GroupsRequestListener());

//then

public class GroupsRequestListener extends BaseRequestListener {

@Override
public void onComplete(final String response, final Object state) {
    dialog.cancel();
    Log.v("response", response);
    Intent myIntent = new Intent(getApplicationContext(),
            GroupsList.class);
    myIntent.putExtra("API_RESPONSE", response);
    startActivity(myIntent);
    }

public void onFacebookError(FacebookError error) {
    dialog.cancel();

    Toast.makeText(getApplicationContext(),
            "Facebook Error: " + error.getMessage(), Toast.LENGTH_SHORT)
            .show();
    }

}
