private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] navMenuTitles;
private TypedArray navMenuIcons;
private ArrayList<NavDrawerItem> navDrawerItems;
private NavDrawerListAdapter adapter;
@SuppressLint("NewApi")
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_welcome);
    mTitle = mDrawerTitle = getTitle();
    navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);
    navMenuIcons = getResources().obtainTypedArray(R.array.nav_drawer_icons);
    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    mDrawerList = (ListView) findViewById(R.id.list_slidermenu);
    navDrawerItems = new ArrayList<NavDrawerItem>();
      navDrawerItems.add(new   NavDrawerItem(navMenuTitles[0],navMenuIcons.getResourceId(0, -1)));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(1, -1)));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[2], navMenuIcons.getResourceId(2, -1)));
navMenuIcons.recycle();
    mDrawerList.setOnItemClickListener(new SlideMenuClickListener());
    adapter = new NavDrawerListAdapter(getApplicationContext(),navDrawerItems);
    mDrawerList.setAdapter(adapter);
    getActionBar().setDisplayHomeAsUpEnabled(true);
    getActionBar().setHomeButtonEnabled(true);
    mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
            R.drawable.ic_drawer, 
            R.string.app_name, 
            R.string.app_name 
    )
{
public void onDrawerClosed(View view) {
getActionBar().setTitle(mTitle);
invalidateOptionsMenu();
 }
 public void onDrawerOpened(View drawerView) {
 getActionBar().setTitle(mDrawerTitle);
 invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
if (savedInstanceState == null) {
displayView(0);
    }
}

private class SlideMenuClickListener implements
    ListView.OnItemClickListener {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position,long id) 
{
displayView(position);}
}

public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.layout.menu, menu);
    menu.getItem(0).getSubMenu();
    return true;
}




private void displayView(int position) {

    Fragment fragment = null;
    switch (position) {
    case 0:
        fragment = new HomeFragment();
        break;
    case 1:
        fragment = BackupFragment.getInstance();
        break;
    case 2:
        fragment = new RestoreFragment();
        break;
    default:
        break;
    }
    if (fragment != null) {
        FragmentManager fragmentManager = getFragmentManager();
        fragmentManager.beginTransaction()
                .replace(R.id.frame_container, fragment).commit();
        mDrawerList.setItemChecked(position, true);
        mDrawerList.setSelection(position);
        setTitle(navMenuTitles[position]);
        mDrawerLayout.closeDrawer(mDrawerList);
    } else {
        //erreur de creation de fraglent
        Log.e("MainActivity", "Error in creating fragment");
    }
}
@Override
public void setTitle(CharSequence title) {
    mTitle = title;
    getActionBar().setTitle(mTitle);
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    mDrawerToggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    mDrawerToggle.onConfigurationChanged(newConfig);
}

}

Answer 1

Your app crashes because ActionBar is not suported below Honeycomb (3.0).

To avoid this problem you must use the support library.

To have a better explanation:

The ActionBar APIs were first added in Android 3.0 (API level 11) but they are also available in the Support Library for compatibility with Android 2.1 (API level 7) and above.

**Caution:** Be certain you import the ActionBar class (and related APIs) from the appropriate package:

• If supporting API levels lower than 11:

  import android.support.v7.app.ActionBar

• If supporting only API level 11 and higher:

  import android.app.ActionBar

Hope it helps!!

Answer 2

Use the MenuDrawer library. Works great!
