Google Map v2 inside android fragment -

i have following code:

public class tab_map extends supportmapfragment {  view view; supportmapfragment gmap; googlemap map;  @override public view oncreateview(layoutinflater inflater, viewgroup container,         bundle savedinstancestate) {     // todo auto-generated method stub     view = inflater.inflate(r.layout.tab_map, container, false);       map = ((supportmapfragment) getfragmentmanager().findfragmentbyid(r.id.fragment1))                 .getmap();     return view; } 

when run application , try , load map tab getting following error:

e/androidruntime(22627): fatal exception: main e/androidruntime(22627): java.lang.nullpointerexception e/androidruntime(22627):    @ maps.ah.bg.b(unknown source) e/androidruntime(22627):    @ bgl.ontransact(sourcefile:115) e/androidruntime(22627):    @ android.os.binder.transact(binder.java:310) e/androidruntime(22627):    @ com.google.android.gms.maps.internal.imapfragmentdelegate$a$a.onresume(unknown source) e/androidruntime(22627):    @ com.google.android.gms.maps.supportmapfragment$a.onresume(unknown source) e/androidruntime(22627):    @ com.google.android.gms.internal.bb$6.b(unknown source) e/androidruntime(22627):    @ com.google.android.gms.internal.bb.a(unknown source) e/androidruntime(22627):    @ com.google.android.gms.internal.bb.onresume(unknown source) e/androidruntime(22627):    @ com.google.android.gms.maps.supportmapfragment.onresume(unknown source) e/androidruntime(22627):    @ android.support.v4.app.fragment.performresume(fragment.java:1503) e/androidruntime(22627):    @ android.support.v4.app.fragmentmanagerimpl.movetostate(fragmentmanager.java:947) e/androidruntime(22627):    @ android.support.v4.app.fragmentmanagerimpl.movetostate(fragmentmanager.java:1088) e/androidruntime(22627):    @ android.support.v4.app.backstackrecord.run(backstackrecord.java:682) e/androidruntime(22627):    @ android.support.v4.app.fragmentmanagerimpl.execpendingactions(fragmentmanager.java:1444) e/androidruntime(22627):    @ android.support.v4.app.fragmentmanagerimpl$1.run(fragmentmanager.java:429) e/androidruntime(22627):    @ android.os.handler.handlecallback(handler.java:725) e/androidruntime(22627):    @ android.os.handler.dispatchmessage(handler.java:92) e/androidruntime(22627):    @ android.os.looper.loop(looper.java:158) e/androidruntime(22627):    @ android.app.activitythread.main(activitythread.java:5777) e/androidruntime(22627):    @ java.lang.reflect.method.invokenative(native method) e/androidruntime(22627):    @ java.lang.reflect.method.invoke(method.java:511) e/androidruntime(22627):    @ com.android.internal.os.zygoteinit$methodandargscaller.run(zygoteinit.java:1083) e/androidruntime(22627):    @ com.android.internal.os.zygoteinit.main(zygoteinit.java:850) e/androidruntime(22627):    @ dalvik.system.nativestart.main(native method)
