android - duplicated id with fragment

Question

I'm trying to applicate drawernavigation (my first fragment is a map & the others are just some fragments with simple layouts).So it runs fine & I can navigate between my fragments but when I return to the first fragment which is a map I got a crash

logcat:

I think this the most impportant:

Duplicate id 0x7f05000c, tag null, or parent id 0xffffffff with another fragment for com.google.android.gms.maps.MapFragment

so this is my code: LoginScreen:a fragmentActivity which make all call for the fragment

public class LoginScreen extends FragmentActivity {

    private DrawerLayout mDrawerLayout;
    private ListView mDrawerList;

    GoogleMap googleMap;

                Toast.makeText(getApplicationContext(), "good connection", Toast.LENGTH_SHORT).show();
            }
          //  setUpMapIfNeeded();

            mTitle = mDrawerTitle = getTitle();

            // load slide menu items
            navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);

Answer 1

use this

<fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true"
         />

and override method onDestroyView() and Just put this code in onDestroyView()

public void onDestroyView() 
 {
    super.onDestroyView(); 
    Fragment fragment = (getFragmentManager().findFragmentById(R.id.map));  
    FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
    ft.remove(fragment);
    ft.commit();
}
