Thanks for reporting these issues. Others have also reported the missing doctype, html and head tags in the docs and we are already looking into fixing it as soon as possible. In the meantime I'd advise you to go and clone the samples directly from github - https://github.com/icenium/. All api samples have their own repositories with the latest improvements applied. You can do that directly from Graphite.
Let me address the error you receive when trying to use the camera sample. Unfortunately, some of the device specific APIs are not yet supported in the simulator (camera is one of them). We are actively working on implementing that and soon you'll see more things working in the simulator also. I tested the sample on a couple of android phones and it worked as expected there. If you experience this error on your android device, please share some details on the device (brand, android version, etc) and what account (email) you use when logging into Icenium.
Thanks in advance for the collaboration. If you have any other questions, don't hesitate to contact us.
