You just need to create new arraylist every time in filter object

@Override 
public Filter getFilter() {
    Filter filter = new Filter() {
        @Override 
        protected FilterResults performFiltering(CharSequence constraint) {
            FilterResults results = new FilterResults();
            // Skip the autocomplete query if no constraints are given. 
            if (constraint != null) {
                // Query the autocomplete API for the (constraint) search string. 

               /**You just need to create new object then crash problem 
                 will not occur**/
                mResultList = new ArrayList<>;

                mResultList = getAutocomplete(constraint);
                if (mResultList != null) {
                    // The API successfully returned results. 
                    results.values = mResultList;
                    results.count = mResultList.size();
                } 
            } 
            return results;
        } 

        @Override 
        protected void publishResults(CharSequence constraint, FilterResults results) {
            if (results != null && results.count > 0) {
                // The API returned at least one result, update the data. 
                notifyDataSetChanged(); 
            } else { 
                // The API did not return any results, invalidate the data set. 
                //notifyDataSetInvalidated(); 
            } 
        } 
    }; 
    return filter;
}
