my code is:

import com.actionbarsherlock.view.MenuItem;

import db.GlobalSettings;

import net.saik0.android.unifiedpreference.UnifiedSherlockPreferenceActivity;
import android.content.Context;
import android.os.Bundle;

public class SettingsActivity extends UnifiedSherlockPreferenceActivity
{
@OverRide
protected void onCreate(Bundle savedInstanceState)
{
setHeaderRes(R.xml.pref_headers);
setSharedPreferencesName("com.out.goout_preferences");
setSharedPreferencesMode(Context.MODE_PRIVATE);
super.onCreate(savedInstanceState);

    try 
    {
        getSherlock().getActionBar().setTitle(R.string.title_activity_settings);
        getSherlock().getActionBar().setHomeButtonEnabled(true);
        getSherlock().getActionBar().setDisplayHomeAsUpEnabled(true);   
    }
    catch (Exception e) {}
}

@Override
public boolean onOptionsItemSelected(MenuItem item) 
{
    if(item.getItemId() == android.R.id.home)
    {
        handleFinish();
        finish();
    }
    return super.onOptionsItemSelected(item);
}

/**this method get the name and the */
private void handleFinish()
{
    try 
    {
        if(!GlobalSettings.getSettings(getApplicationContext()).isUserDetSent())
        {
            String age = GlobalSettings.getSettings(getApplicationContext()).getUserAge();
            String gender = GlobalSettings.getSettings(getApplicationContext()).getUserGender();

            if(!age.equals("") && !gender.equals(""))
            {
                //send the details to the server
                GlobalSettings.getSettings(getApplicationContext()).setUserDetSent(true);
            }
        }
    }
    catch (Exception e){}
}

@Override
public void onBackPressed() 
{
    handleFinish();
    super.onBackPressed();
}

}

Thanks in advance.
