Answer 1

pd.setCancelable(true);
    pd.setOnCancelListener(cancelListener);
    bCancelled=false;

 pd is your progressdialog box

and now use cancelListner

    OnCancelListener cancelListener=new OnCancelListener(){
    @Override
    public void onCancel(DialogInterface arg0){
        bCancelled=true;
        finish();
    }
