Let's follow up this discussion at the Neptune Community
(this forum will be kept in read-only mode)
In the Neptune Designer, I have placed an image (sap.m -> SimpleControls -> Image) in the middle position of a bar. It displays fine when I Run in Browser/Run in Wrapper but doesn't appear when I try to view it from a mobile device eg. iPhone.
Does anyone know how to have an image displayed on a mobile device?
Using images on your mobile App is quite different from the browser. The relative URL is actually pointing to your mobile File area and not the SAP Server. But, the sap.m.Image should render the image as imagedata, base64 encoded and embedded into the HTML5 document.
What URL are you using for the image source ?
In NAD 3.0 and on a mobile App we expect the URL to be an internal URL. If you upload the Image into the MIME Object in NAD and set the relative URL as you have in MIME Preview, all will work fine. Or you can use binding and bind the URL to a structure and it will be visible.
In NAD 3.1 it will also be possible to use external image URL in the mobile App.
