i have commented the line which cause error

public class MainActivity extends FragmentActivity
implements ActionBar.TabListener {

    private SectionsPagerAdapter mSectionsPagerAdapter;

    private ViewPager mViewPager;

    public static final String TAG = MainActivity.class.getSimpleName();


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

        ParseUser currentUser = ParseUser.getCurrentUser();

        if (currentUser == null) {
            navigateToLogin();
        } else {
            Log.i(TAG, currentUser.getUsername());
        }

        android.support.v7.widget.Toolbar toolbar = (android.support.v7.widget.Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);                            // error cannot resolve symbol method setSupportActionBar()
        getSupportActionBar().setDisplayHomeAsUpEnabled(true); // error cannot resolve symbol method setSupportActionBar()


        mSectionsPagerAdapter = new SectionsPagerAdapter(this, getSupportFragmentManager());

        mViewPager = (ViewPager) findViewById(R.id.container);
        mViewPager.setAdapter(mSectionsPagerAdapter);

        TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
        tabLayout.setupWithViewPager(mViewPager);
    }
}
