Question

I'm new to android development and, I'm getting deprecated errors in this code, please someone show me how to fix this code without errors.

• The method setNavigationMode(int) from the type ActionBar is deprecated.

• The method addTab(ActionBar.Tab) from the type ActionBar is deprecated.

• The method setSelectedNavigationItem(int) from the type ActionBar is deprecated.

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        
        context = this;
        String mBaseFolderPath = android.os.Environment.getExternalStorageDirectory() + File.separator + "Folder2"
                + File.separator;
        if (!new File(mBaseFolderPath).exists()) {
            new File(mBaseFolderPath).mkdir();
        }

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

        /**
         * on swiping the viewpager make respective tab selected
         */
        viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {

            @Override
            public void onPageSelected(int position) {
                // on changing the page
                // make respected tab selected
                actionBar.setSelectedNavigationItem(position);
            }

            @Override
            public void onPageScrolled(int arg0, float arg1, int arg2) {
            }

            @Override
            public void onPageScrollStateChanged(int arg0) {
            }
        });

    }

Adapter.

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;

public class VDTabsAdapter extends FragmentPagerAdapter {
    public VDTabsAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int index) {

        switch (index) {
            case 0:
               
                return new VDFragment();
            case 1:
                
                return new ADFragment();
        }

        return null;
    }

    @Override
    public int getCount() {
        // get item count - equal to number of tabs
        return 2;
    }
    
}

Code 2.

@Override
    public void onTabSelected(Tab tab, FragmentTransaction ft) {
        // on tab selected
        // show respected fragment view
        viewPager.setCurrentItem(tab.getPosition());
        if (tab.getPosition() == 1) {
            Log.e("UPDATED", " SELECTED");
            final DownloadsFragment fragment = ((VDFragment) getSupportFragmentManager()
                    .findFragmentByTag("android:switcher:" + R.id.pager + ":1"));
            fragment.updateVD();

ERROR.

• The method getPosition() from the type ActionBar.Tab is deprecated
