If you are using AsynTask for fetching data from the server, then you can define an instance of that Asynctask. And when user presses back button you can cancel that task specifically like this 

 FetchDataListTask fetchDataListAsyncTask;
 fetchDataListAsyncTask = new FetchDataListTask(true);
 fetchDataListAsyncTask.execute();

And put this in your Onbackpressed() method

if (fetchLeadListAsyncTask != null) {
                fetchLeadListAsyncTask.cancel(true);
            }

Instead of using tag to cancel all request. you can use filter,

mRequestQueue.cancelAll(new RequestQueue.RequestFilter() {
@Override
    public boolean apply(Request<?> request) {
        return true;
    }
});

Hope this help.
