Create tabs swipe view failed

How to fix Main is not abstract and does not override abstract method onTabReselected(Tab,FragmentTransaction) in TabListener ? Not sure whether I implementing in the correct method, but the debugger said import android.app.FragmentTransaction; is unused statement.

I get the source from here. 

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
import android.app.ActionBar;
import android.app.FragmentTransaction; // unused statement 


public class Main extends FragmentActivity implements ActionBar.TabListener {

    private ViewPager viewPager;
    private TabsFragmentPagerAdapter mAdapter;
    private ActionBar actionBar;
    // Tab titles
    private String[] tabs = {"Top Rated", "Games", "Movies"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Initilization
        viewPager = (ViewPager) findViewById(R.id.pager);
        actionBar = getActionBar();
        mAdapter = new TabsFragmentPagerAdapter(getSupportFragmentManager());

        viewPager.setAdapter(mAdapter);
        actionBar.setHomeButtonEnabled(false);
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

        // Adding Tabs
        for (String tab_name : tabs) {
            actionBar.addTab(actionBar.newTab().setText(tab_name)
                    .setTabListener(this));
        }
    }
}

ActionBar.TabListener is an interface. So, if you implementing ActionBar.TabListener in your activity, you must implementing these method in your activity:

onTabReselected(ActionBar.Tab tab, FragmentTransaction ft){}
onTabSelected(ActionBar.Tab tab, FragmentTransaction ft){}
onTabUnselected(ActionBar.Tab tab, FragmentTransaction ft){}

Ref: http://developer.android.com/reference/android/app/ActionBar.TabListener.html

Add abstract in front of public

public abstract class Main extends FragmentActivity implements ActionBar.TabListener {
