+   If the API fails to be called, you are advised to use the **try/catch** statement to capture error information that may occur in the code. Example:
+
+    ```
+    try {
+      sensor.once(sensor.sensorType.SENSOR_TYPE_ACCELEROMETER,function(data) {
+          console.info("Data obtained successfully. data=" + data);// The call is successful, and the obtained sensor data is printed.
+      });
+    } catch (error) {
+      console.error(error);
+    }
+    ```
