 The initialization methods, `buildAndInit` and `buildAndInitAsync` return or resolve to an `EppoClient` instance with a loaded configuration.
 
+### Mobile Polling
+
+The SDK can be configured to poll the Eppo API periodically to get the latest configuration.
+
+<ApiOptionRef
+  name="pollingIntervalMs"
+  type="long"

+    super.onPause();
+    EppoClient.getInstance().pausePolling();
+  }
+
+  @Override
+  public void onResume() {
+    super.onResume();
+    EppoClient.getInstance().resumePolling();
