Open Navigation Drawer at startup

Question

I'm fairly new to android programming and developed an app that has a Navigation Drawer implemented. Per Google guidelines, i'd like the NavDraw to start open but am unable to do this.

This is my onCreate (I guess this is where I should implement this feature, right?)

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActionBar().getThemedContext(), android.R.layout.simple_list_item_1, menuEntries);

    final DrawerLayout drawer = (DrawerLayout)findViewById(R.id.drawer_layout);
    final ListView navList = (ListView) findViewById(R.id.drawer);

    getActionBar().setDisplayHomeAsUpEnabled(true);
    getActionBar().setHomeButtonEnabled(true);

    drawerToggle = new ActionBarDrawerToggle(
            this,
            drawer,
            R.drawable.ic_drawer,
            R.string.drawer_open,
            R.string.drawer_close
    )

(...)

Use drawer.openDrawer(Gravity.LEFT);

If targeting international users, use GravityCompat.START instead. – wize Oct 23 '15 at 18:19
You should probably wrap in `if (savedInstanceState == null)`, so that the drawer doesn't open on configuration/orientation change – Jacob R Aug 30 '17 at 20:40

You can use

 drawer.openDrawer(Gravity.LEFT);

or

drawer.openDrawer(Gravity.RIGHT`);
