i able username , email in drawer not image,

enter image description here check put in here, check object null-ivty.

if (e == null) {

i getting error message

enter image description here

i believe getting 'no results found query' because query parsequery("user") not search users class.

try changing 

parsequery<parseobject> query =  new parsequery("user")

to 

parsequery<parseuser> query = parseuser.getquery();

this how users should queried according to: https://parse.com/docs/android/guide#users-querying

however still not think need query when interested in current user:

    if(currentuser != null){         log.d("mainactivity", "came current user check statement");     currentuser.fetchifneededinbackground(new getcallback<parseobject>() {          @override         public void done(parseobject object, parseexception e) {               if (e == null) {                 parsefile fileobject = (parsefile) object.getparsefile("imageprofile");                   fileobject.getdatainbackground(new getdatacallback() {                      @override                     public void done(byte[] bytes, parseexception e) {                         if (e == null) {                             toast.maketext(mainactivity.this, "welcome back", toast.length_long).show();                             bitmap bmp = bitmapfactory.decodebytearray(bytes, 0, bytes.length);                              // header_image image = (imageview) fin                         } else {                             alertdialog.builder builder = new alertdialog.builder(mainactivity.this);                             builder.setmessage(e.getmessage());                             builder.settitle("sorry");                             builder.setpositivebutton("ok", new dialoginterface.onclicklistener() {                                 @override                                 public void onclick(dialoginterface dialoginterface, int i) {                                     dialoginterface.dismiss();                                 }                             });                             alertdialog dialog = builder.create();                             dialog.show();                         }                      }                 });             } else {                 alertdialog.builder builder = new alertdialog.builder(mainactivity.this);                 builder.setmessage(e.getmessage());                 builder.settitle("sorry");                 builder.setpositivebutton("ok", new dialoginterface.onclicklistener() {                     @override                     public void onclick(dialoginterface dialoginterface, int i) {                         dialoginterface.dismiss();                     }                 });                 alertdialog dialog = builder.create();                 dialog.show();              }          }     });
