Thumbnail bitmap image doesn't show up in fragment class -

-

the dilemma want use mediastore.images.thumbnails.getthumbnail thumbnail sdcard , show in fragment class (which requested in mainactivity). here code. there no error in code imageview shows nothing @ all. 

public class fragmentclass extends fragment { string tag = "hi"; imageview image; long imageid;  public fragmentclass() {} @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate); }  @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {      view v = inflater.inflate(r.layout.fragment_fragment_class, container, false);      image = (imageview) v.findviewbyid(r.id.imageview);      string projection[] = { mediastore.images.thumbnails._id, mediastore.images.thumbnails.data};      contentresolver contentresolver = getactivity (). getcontentresolver();      cursor cursor = mediastore.images.thumbnails.query(contentresolver,             mediastore.images.thumbnails.external_content_uri,             projection);  cursor.movetofirst();      imageid = cursor.getint(cursor.getcolumnindex(mediastore.images.thumbnails._id));      cursor.close();       final bitmapfactory.options bmoptions = new bitmapfactory.options();     bmoptions.insamplesize =2;      bitmap bitmap = mediastore.images.thumbnails.getthumbnail(             contentresolver,             imageid,             mediastore.images.thumbnails.micro_kind, bmoptions);      //image.setimagebitmap(bitmap);      image.setimagebitmap(bitmap);     // inflate layout fragment     return v; }

}

why not using recent-images library? makes thumbnails of device photos , set them in gridview, can custom purpose.
