In the first part of the course series, we built a ProjectRanker app for iOS Tablet and Android Smartphone. Now, I’ll show you how to change our current solution for using more tools but less code without affecting the user experience. You will be able to answer questions on why to use OData and how to introduce it in SAP mobile projects. You will have a general understanding about the role of the SAP Netweaver Gateway that revolutionized the SAP backend systems for mobile communications. I will be also explaining why SAP recommends the SAP Mobile Platform and how it fits into this big picture. We will be also coding in C# by using SAP SDK as Xamarin's Component for sending OData requests to SAP Mobile Platform.
