HTTPS  is recommended and desired. There must be a signed by registered certificate authority in each SAP system connected to.&#x20;

However, if you cannot provide HTTPS the application will work except for certain features that require a HTTPS connection - mainly offline support. PreBilt will also not work as a Progressive Web Application without HTTPS. If an APK is required, a configuration change in the Android manifest file must be made to allow unsecure HTTP connections.

There must be a direct connection from device to SAP and the domain is resolvable by the device.
