I have an iPad and Android phone (iPad Air,iOS 8 and Samsung Note 3, android 4.3). On the iPad I can configure the app to go to /share and it works. I see my files as well as all my sites. On the android it will not log in with /share but does with /alfresco. the problem with /alfresco is that I don't see "my files" from the /share app. I'm running alfresco community 5.0c i believe.
for the Alfresco Mobile app you should never enter /share as the endpoint. Only Alfresco is valid - it may be that the iOS Version just has a naiive fallback in place in case the user-entered endpoint is incorrect (I seem to remember our devs mentioning something in this direction when they customized the app).
I opened the app and used /alfresco/ and shazam, my files showed up, but I couldn't get any sites (threw an auth error). I rebooted the app, changed it to /alfresco and now everything is working as I would have expected. Amazing Go figure eh? Thanks for the help btw.
