Cloud vision Web Detection in Android

Hi i have been implementing an application to detect image from Cloud Vision. I have a sample source code for detecting Data's in the following link,

https://github.com/GoogleCloudPlatform/cloud-vision/blob/master/android/CloudVision/app/src/main/java/com/google/sample/cloudvision/MainActivity.java

But this one doesn't have an option to detect Web Entities from cloud so can anyone help me to let me know the possibilities of cloud detection with Android SDK given in the link.

Thanks in advance.
