public class MainActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        // If the Android version is lower than Jellybean, use this call to hide        // the status bar.        if (Build.VERSION.SDK_INT < 16) {            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,                    WindowManager.LayoutParams.FLAG_FULLSCREEN);        }        setContentView(R.layout.activity_main);    }    ...}

7. ActionBar actionBar = getActionBar();
8. actionBar.hide();

View decorView = getWindow().getDecorView();// Hide the status bar.int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;decorView.setSystemUiVisibility(uiOptions);// Remember that you should never show the action bar if the// status bar is hidden, so hide that too if necessary.ActionBar actionBar = getActionBar();actionBar.hide();

7. | View.SYSTEM_UI_FLAG_FULLSCREEN;
8. decorView.setSystemUiVisibility(uiOptions);
