Android - Window leak error on ProgressDialog when device is in landscape -

i have looked @ many questions here , searched on internet couldn't find specific solution. main problem other questions refer is, window leak error when go portrait landscape or vice versa. , answer mainly, because activity destroyed , recreated, hence window leak error.

but problem is, device in landscape, , app working fine, previous activities smoothly running, when try display progressdialog, window leak error thrown. exact same code works fine when in portrait orientation.

class downloadyearchartasynctask extends asynctask<string, integer, boolean> {     private string username;     private string city;      private resources resources;     private location locationofcity = null;      private progressdialog progressdialog;      public downloadyearchartasynctask(string username)     {         this.username = username;     }      @override     protected void onpreexecute() {         super.onpreexecute();         resources = getresources();         setrequestedorientation(activityinfo.screen_orientation_nosensor);          progressdialog = new progressdialog(cityactivity.this);         progressdialog.settitle(r.string.title_progress_dialog);         progressdialog.setmessage(resources.getstring(r.string.first_message_progress_dialog));         progressdialog.setindeterminate(true);         progressdialog.setcancelable(false);         progressdialog.setprogressstyle(progressdialog.style_spinner);         progressdialog.show();     }      @override     protected void onpostexecute(boolean result) {         super.onpostexecute(result);         progressdialog.dismiss();          boolean userupdated = false;          if(locationofcity != null && city != null && !city.isempty()) {             try             {                 userdao userdao = new userdao(cityactivity.this);                 user user = userdao.readuser();                  if(user == null) {                     if(username != null && !username.isempty()) {                         user = new user(0, username, city, locationofcity.getlatitude(), locationofcity.getlongitude());                         userupdated = userdao.createuser(user);                     }                 }                      if(username == null) {                         user.setlocation(city);                         user.setlatitude(locationofcity.getlatitude());                         user.setlongitude(locationofcity.getlongitude());                          userupdated = userdao.updateuser(user);                     }                 }                 userdao.close();             }             catch (exception e) {                 e.printstacktrace();             }         }          setrequestedorientation(activityinfo.screen_orientation_sensor);          if(userupdated)         {             intent intent = new intent(cityactivity.this, todayactivity.class);             intent.setflags(intent.flag_activity_new_task | intent.flag_activity_clear_task);             startactivity(intent);             overridependingtransition(r.anim.slide_in_from_right, r.anim.slide_out_to_left);         }     }      @override     protected void onprogressupdate(integer... values) {         super.onprogressupdate(values);         progressdialog.setprogress(values[0]);     }      @override     protected boolean doinbackground(string... params) {         boolean alldaysentered = false;          try {             city = params[0];             locationofcity = myjsonutil.getlocationofcity(params);              list<day> yearchart = myjsonutil.getyearchart(locationofcity.getlatitude(), locationofcity.getlongitude());               if(yearchart != null && !yearchart.isempty()) {                 yearchartdao yearchartdao = new yearchartdao(cityactivity.this);                 alldaysentered = yearchartdao.createyearchartwithdays(yearchart);                 yearchartdao.close();             }         }         catch (exception e) {             e.printstacktrace();         }          return alldaysentered;     } } 

any suggestions or solutions appreciated.

the problem code, used setrequestedorientation(activityinfo.screen_orientation_nosensor);

because, according kevin gaudin's comment on this answer.

it looks if call setrequestedorientation(activityinfo.screen_orientation_nosensor); when device not in default orientation usage, activity orientation changed (destroyed , recreated) device default orientation. example, on phone, if hold in landscape orientation, activity switched portrait , landscape when reactivating sensors. same opposite issue archos a5 : using in portrait causes activity switched landscape , portrait.

here solution found, answered commonsware. solution little lengthy.

so people in rush, technique used solution not perfect.

1 - in manifest, add android:configchanges="orientation|screensize" activity in want show progressdialog.

2 - in activity, override onconfigurationchange(configuration newconfig):

@override public void onconfigurationchanged(configuration newconfig) {     super.onconfigurationchanged(newconfig); }
