what leaked window?  

the windowleaked exception in case happening because not dismissing myprogressdialog before finishing activity. hence leaking memory associated it.

general case :

the windowleaked exception happens when have sort of async task finishing after activity began it, destroyed.this type of exception occurred in case dialogs,where did not dismiss dialogs before activity context destroyed.

so better put check before showing dialog, follows:

if(getactivity()!= null && !getactivity().isfinishing()){             dialog.show(); } 

solution above issue dismiss myprogressdialog before finish activity.

modify code follows:

protected void onpostexecute(string file_url) {      // first line should       if ( myprogressdialog!=null && myprogressdialog.isshowing() ){         myprogressdialog.dismiss();     }      // rest of code  }
