There have been posts regarding navigation between views. Adding on to those, I would like to share some information on Navigating from App to SplitApp to App i.e, Full Page to Master Detail to Full Page.
To achieve this, two different targetControl were in component.js, one for App and other for SplitApp. As per our routing requirement routes can be provided accordingly. I have used JS views, same can be achieved with XML views.
The code can be seen at https://github.com/mabhishekk/SAP-UI5-Navigation-App-to-SplitApp-
