ID mit Fragment dupliziert

Ich versuche, Zeichennavigation anzuwenden (mein erstes Fragment ist eine Karte und die anderen sind nur einige Fragmente mit einfachen Layouts). So läuft es gut und ich kann zwischen meinen Fragmenten navigieren, aber wenn ich zum ersten Fragment zurückkehre, das eine Karte I ist habe einen Absturz

Ich denke das ist das Wichtigste:

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

}

    mCurrentPosition = position;
}
@Override
public void onStart() {
    // TODO Auto-generated method stub
    super.onStart();
     Bundle args = getArguments();
     if (args != null) {
         // Set article based on argument passed in
         updateArticleView(args.getInt(ARG_POSITION));
     } else if (mCurrentPosition != -1) {
         // Set article based on saved instance state defined during onCreateView
         updateArticleView(mCurrentPosition);
     }
}
}

Ich denke, dass das Problem in onResume & onCreateView Methoden liegt! Hoffe, dass Sie mir helfen, danke.
