+This enables the user to trigger the table refresh on a single swipe. To listen for this user interaction you have to set an `SwipeToRefreshListener` to your tableview.
+```java
+    carTableView.setSwipeToRefreshListener(new SwipeToRefreshListener() {
+        @Override
+        public void onRefresh(final RefreshIndicator refreshIndicator) {
+            // your async refresh action goes here
+        }
