Attempt to invoke virtual method 'android.os.Parcelable android.os.Bundle.getParcelable(java.lang.String)' null object reference -

i making app in feature user can upload images , video server working on activity want use in fragment. try code effectively, efficiently , not getting error during compiling , app runs when click on fragment shows "unfortunately app has stopped " , in log cat getting error:

java.lang.nullpointerexception: attempt invoke virtual method 'android.os.parcelable android.os.bundle.getparcelable(java.lang.string)' on null object reference

and points line:

 public void onactivitycreated(bundle savedinstancestate) {         super.onactivitycreated(savedinstancestate);    line  ➦   fileuri = savedinstancestate.getparcelable("file_uri");      } 

i don't know whats wrong

my code:

public class tabfragment4 extends fragment implements  view.onclicklistener{  view parentholder; private static final string tag = mainactivity.class.getsimplename();   int req_code = 100; int video_code = 20;

seems savedinstancestate == null use this:

if (savedinstancestate != null) {     fileuri = savedinstancestate.getparcelable("file_uri");  } else {     fileuri = ??? - want in else case; }
