Apologies for the delayed response.
Using ODataViewer is easy in Zentity as shown in the below screen shot. Zentity Getting Started Guide illustrates the usage of OData view in detail (page 32).
How do I connect it with an Android phone?
You cannot connect to Zentity OData View with Android as Zenity client will not be installed on this platform. If you able to connect to a machine through Android phone where Zentity client is installed then you can work remotely.
Please let me know if this helps you.
