My app frequently throws android.view.WindowLeaked exception -- -

-

my app throws exception below:

e/windowmanager( 6282): android.view.windowleaked: activity com.myactivity has leaked window com.android.internal.policy.impl.phonewindow$decorview@4479b710 added here

the app shows progress dialog when main activity starts , starts task. when task done, dismiss progress dialog.

my code below. can me?

public class myactivity extends activity {  private static int id_dialog_progress = 2001;  public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);             setcontentview(r.layout.my_activity);     showdialog(id_dialog_progress);     new mytask().execute(null, null, null); }  @override protected dialog oncreatedialog(int id) {     if (id == id_dialog_progress) {         progressdialog loadingdialog = new progressdialog(this);         loadingdialog.settitle("");         loadingdialog.setmessage("");         loadingdialog.setindeterminate(true);         loadingdialog.setcancelable(false);         return loadingdialog;     }      return super.oncreatedialog(id); }  private class mytask extends asynctask<void, void, void> {      @override     protected void doinbackground(void... arg0) {              /* expensive here...*/              /* start other activity*/             intent intent = new intent(myactivity.this, otheractivity.class);             startactivityforresult(intent, 1000);         }          return null;     }      protected void onpostexecute(void arg0) {         dismissdialog(id_dialog_progress);     } } }

most of time, exception thrown showdialog() call. other time, exception thrown dismissdialog() call.

thank in advance!

you're starting new activity in doinbackground() before dismiss dialog in onpostexecute(), causing dialog leak. move 

intent intent = new intent(myactivity.this, otheractivity.class); startactivityforresult(intent, 1000);

to onpostexecute() after dismissdialog() call , see happens.
