android - Intents and google maps api v2 -

i know question silly, i'm bit confused intents.from code below want separate in 2 classes showmap , locationmap.how can this??the fist contain map(fragmentactivity), call second class in want find user's current location , return marker map(first activity).thanks in advance!here class want separate:

public class locationmap extends fragmentactivity implements locationlistener{  private googlemap googlemap; private latlng latlng; textview tvlocation; markeroptions markeroptions;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.location_maps);       // getting google play availability status                int status = googleplayservicesutil.isgoogleplayservicesavailable(getbasecontext());      // showing status     if(status!=connectionresult.success){ // google play services not available          int requestcode = 10;         dialog dialog = googleplayservicesutil.geterrordialog(status, this, requestcode);         dialog.show();      }else { // google play services available          // getting reference supportmapfragment of activity_main.xml         supportmapfragment fm = (supportmapfragment) getsupportfragmentmanager().findfragmentbyid(r.id.map);          // getting googlemap object fragment         googlemap = fm.getmap();         //setting zoomin-zoomout bar in screen         googlemap.getuisettings().setzoomcontrolsenabled(true);          // enabling mylocation layer of google map         googlemap.setmylocationenabled(true);          //googlemap.setmaptype(googlemap.map_type_normal);         // getting locationmanager object system service location_service         locationmanager locationmanager = (locationmanager) getsystemservice(location_service);          // creating criteria object retrieve provider         criteria criteria = new criteria();          // getting name of best provider         string provider = locationmanager.getbestprovider(criteria, true);          // getting current location         location location = locationmanager.getlastknownlocation(provider);          if(location!=null){             onlocationchanged(location);             new reversegeocodingtask(getbasecontext()).execute(latlng);                        }         locationmanager.requestlocationupdates(provider, 20000, 0, this);     }   }  @override public boolean oncreateoptionsmenu(menu menu) {     // inflate menu; adds items action bar if present.     getmenuinflater().inflate(r.menu.location_maps, menu);

    searchview.setsearchableinfo(searchmanager             .getsearchableinfo(getcomponentname()));      return super.oncreateoptionsmenu(menu);   }   @override public boolean onoptionsitemselected(menuitem item) {     // take appropriate action each action item click     switch (item.getitemid()) {     case r.id.action_search:          return true;

      }   @override public void onproviderdisabled(string provider) {     // todo auto-generated method stub            toast.maketext( getapplicationcontext(),     "gps disabled",toast.length_short ).show();
