Question

My Question is i need to open SAME FRAGMENT from Navigation Drawer's every List Item 's, and when fragment display, If AsynTask execution is On Going then AsyncTask execution should be cancel.

How can i do it?

I tried so many ways to accomplish this but i failed everytime.

I used asynctaskObject.cancel(true);

So Can anybody please answer. i hope i'll get the result.

i found solution of my problem.

We just need to make request in onStop method like below :

@Override
public void onStop() {
    super.onStop();
    if(asyncTaskObject!=null){
        asyncTaskObject.cancel(true);
    }
}

This way whenever we request from Navigation Drawer's List Item on Same Fragment, at that time fragment call onStop() method and i just call task.cancel(true);

And Thanks to @MysticMagic. i resolved this issue from your given link.

For forceful cancel() to work, you will need to check if its cancelled in doInBackground.

@Override
protected String doInBackground(String... params) 
{
    . 
    .
    if(isCancelled()){
        break;
    }
    .
}

Hope it helps.
