possible duplicate of Android: activity has leaked window due to progress dialog? – Sterilant

please change Void to void – Dear

probably App is crashing be because you are trying to update UI element from doInBackground so use onPostExecute for updating ui elements instead of doInBackground – Subinfeudation

yeah, rite.. it was showing bcz of UI element from doInBackground... thank you so much. – Auroraauroral

Answer 1

This error will happen if your activity has been destroyed but you dialog is still showing. So You have added these code in your activity's onDestroy()

@Override
public void onDestroy() {
    super.onDestroy();
    if (dialog != null) {
        dialog.dismiss();
        dialog = null;
    }
}

App was crashing i was trying to update UI element from doInBackground. – Auroraauroral

U cannot change UI from another background thread. Try changing from postExecute – Horseplay

rite, vivek. But then why it is working when I am not sending data to my computer local server. I have changed it to main server of my company and that time only, I got this error. – Auroraauroral

super.onDestroy() should be called first. – Worldly

Thank Johan S, I confirm that you are right :). I have misunderstood it for a very long time. – Glycerinate

LOL i am impressed you know why .. I didt declare dialog and when I i hve used this on destroy .. my issue got fixed lol :) thanks – Rewrite

Answer 2

Possibly Its Because of you are writing

textValidation.setText(e.toString());

inside the function,

doInBackground()

which is updating UI which is allowed by android in doInBackground() method. So somehow if you put this line in

postExecute()

then this problem will get resolved.
