Sliding menu problem (jfeinstein lib) - Android Q&A, Help & Troubleshooting

Hi guys I'm having problem with the jfeistein sliding menu. I have correctly imported it but i have only a problem. When I click on the "test" item it opens the related fragment but it doesn't autoclose the menu as it should.
MAINACTIVITY
Code:
public class MainActivity extends Activity {
private SlidingMenu slidingMenu ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
slidingMenu = new SlidingMenu(this);
slidingMenu.setMode(SlidingMenu.LEFT);
slidingMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
slidingMenu.setShadowWidthRes(R.dimen.slidingmenu_shadow_width);
slidingMenu.setShadowDrawable(R.drawable.slidingmenu_shadow);
slidingMenu.setBehindOffsetRes(R.dimen.slidingmenu_offset);
slidingMenu.setFadeDegree(0.35f);
slidingMenu.attachToActivity(this, SlidingMenu.SLIDING_CONTENT);
slidingMenu.setMenu(R.layout.slidingmenu);
getActionBar().setDisplayHomeAsUpEnabled(true);
}
@Override
public void onBackPressed() {
if ( slidingMenu.isMenuShowing()) {
slidingMenu.toggle();
}
else {
super.onBackPressed();
}
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ( keyCode == KeyEvent.KEYCODE_MENU ) {
slidingMenu.toggle();
return true;
}
return super.onKeyDown(keyCode, event);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
this.slidingMenu.toggle();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
SLIDING MENU FRAGMENT
Code:
public class SlidingMenuFragment extends Fragment implements ExpandableListView.OnChildClickListener {
private SlidingMenu slidingMenu ;
private ExpandableListView sectionListView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
List<Section> sectionList = createMenu();
View view = inflater.inflate(R.layout.slidingmenu_fragment, container, false);
this.sectionListView = (ExpandableListView) view.findViewById(R.id.slidingmenu_view);
this.sectionListView.setGroupIndicator(null);
SectionListAdapter sectionListAdapter = new SectionListAdapter(this.getActivity(), sectionList);
this.sectionListView.setAdapter(sectionListAdapter);
this.sectionListView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
@Override
public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {
return true;
}
});
this.sectionListView.setOnChildClickListener(this);
int count = sectionListAdapter.getGroupCount();
for (int position = 0; position < count; position++) {
this.sectionListView.expandGroup(position);
}
return view;
}
private List<Section> createMenu() {
List<Section> sectionList = new ArrayList<Section>();
Section oDemoSection = new Section("Demos");
oDemoSection.addSectionItem(101,"Test", "lol");
oDemoSection.addSectionItem(102, "Airport (AsyncTask)", "lol");
Section oGeneralSection = new Section("General");
oGeneralSection.addSectionItem(201, "Settings", "lol");
oGeneralSection.addSectionItem(202, "Rate this app", "lol");
oGeneralSection.addSectionItem(203, "Eula", "lol");
oGeneralSection.addSectionItem(204, "Quit", "lol");
sectionList.add(oDemoSection);
sectionList.add(oGeneralSection);
return sectionList;
}
public void toggle() {
slidingMenu.toggle();
}
@Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
Fragment fragment=null;
switch ((int)id) {
case 101:
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.frame_container, new Net()).commit();
break;
case 102:
//TODO
break;
case 201:
//TODO
break;
case 202:
//TODO
break;
case 203:
//TODO
break;
case 204:
//TODO
break;
}
return false;
}}
