public class Utils {

public static void hideNavigations(Activity context) {
    View decorView = context.getWindow().getDecorView();
    decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION

    super.onResume();
    Utils.hideNavigations(this);

Since the system bar is used to navigate in android there is not an easy way to achieve this, you can dissable/dim the controls:

View v = findViewById(R.id.view_id);
v.setSystemUiVisibility(View.STATUS_BAR_HIDDEN);

But you can get the size of the screen without the systembar (not sure from what version, I think 3.1)

Method rawW = Display.class.getMethod("getRawWidth");
Method rawH = Display.class.getMethod("getRawHeight");
int width = (Integer)mGetRawW.invoke(dp);
int height = (Integer)mGetRawH.invoke(dp);

If your app has root access there is also a way to achieve it: http://ppareit.github.com/HideBar/

You can't hide it but you can simply disable it, except home. Try this link. . Using SYSTEM_UI_FLAG_LOW_PROFILE you can dim your system bar and using onWindowFocusChanged() can take the focus and collapse it.
