android - NullPointerException when saving Bitmap to SD card -

i'm trying take picture , save sd, @ point (after photo has been taken) nullpointerexception. here's code:

    package com.social.bearv2; import java.io.file; import java.io.ioexception; import java.text.simpledateformat; import java.util.date;  import android.net.uri; import android.os.bundle; import android.os.environment; import android.provider.mediastore; import android.annotation.suppresslint; import android.app.activity; import android.content.intent; import android.graphics.bitmap; import android.view.menu; import android.view.view; import android.view.view.onclicklistener; import android.widget.button; import android.widget.imagebutton; import android.widget.imageview; import android.widget.toast;  @suppresslint("newapi") public class articolo extends activity {  private static final int capture_image_capture_code = 0;  intent i;  private button ib;  private imageview imview;    @override  protected void oncreate(bundle savedinstancestate) {   super.oncreate(savedinstancestate);   setcontentview(r.layout.article);   ib = (button) findviewbyid(r.id.insert);   imview = (imageview) findviewbyid(r.id.imview);     ib.setonclicklistener(new onclicklistener() {    @override    public void onclick(view v) {        file photofile = null;        try {            photofile = createimagefile();        } catch (ioexception ex) {            // error occurred while creating file        }        // continue if file created        if (photofile != null) {     intent = new intent(mediastore.action_image_capture);     i.putextra(mediastore.extra_output,             uri.fromfile(photofile));     startactivityforresult(i, capture_image_capture_code);    }    }   });  }  protected void onactivityresult(int requestcode, int resultcode, intent data) {   if (requestcode == capture_image_capture_code) {    if (resultcode == result_ok) {        try {     toast.maketext(this, "image captured", toast.length_long).show();     bundle extras = data.getextras();     bitmap imagebitmap = (bitmap) extras.get("data");       imview.setimagebitmap(imagebitmap);    } catch (nullpointerexception ex) {     }    } else if (resultcode == result_canceled) {     toast.maketext(this, "cancelled", toast.length_long).show();    }   }  }   private file createimagefile() throws ioexception {         string timestamp = new simpledateformat("yyyymmdd_hhmmss").format(new date());         string imagefilename = "bear_" + timestamp + ".jpg";         file photo = new file(environment.getexternalstoragedirectory(),  imagefilename);         return photo;     }  } 

note line of code gives me exception "bundle extras = data.getextras();"

and logcat:

any suggestions?

here intent data null... stacktrace says data null...

resultinfo{who=null, request=0, result=-1, data=null // here} 

and accessing null instance @ bundle extras = data.getextras();

you not receive data when capture image passing output location. captured image saved @ location photofile(the location created)...
