I've got a mobile app developed in 4.6. Part of our app includes the ability to store files on our remote servers which users can access. In its simplest form the app displays a list of the files which the user can then click on to open. I tried throwing a navigateToURL which works - although it's ugly as hell. It opens the browser which then throws it to the os. Again, it works, but I know there's got to be a better way.
Files will include PDF, images (jpg, tiff, etc), and Word and Excel docs.
