While creating some AEM Forms (LiveCycle) demos for some clients, it became very apparent that they wanted to see forms in action on mobiles and tablets. One of the easiest ways I have found to do this is by using Charles.
By ensuring your demo computer and mobile/tablet are on the same network, and manually configuring the proxy settings on your device, you can route all traffic via Charles and force your device to pass through your computer when browsing. So if you have an HTML form on your computer at the URL http://localhost:8080/lc/content/xfaforms/profiles/default.html?contentRoot=repository%3A%2F%2F%2FApplications%2FFormDemo%2F1.0%2Fforms&template=SampleForm.xdp&dataRef=http://localhost:8080/lc/content/dam/lcapplications/temp_archive_storage/tempArchive_4895793046486&dataRef=4895793046486 (as is generated in the Forms Manager preview), you can open this form on your device by substituting localhost with the IP address of your computer – you now can test and demo forms on a mobile device!
I’ve not tested other AEM functionality in this way yet, but I don’t see why it would not work the same way.
