I'm a teacher in the UK and have 30 kids in my class.We have bought 35 (older) Nexus 7 tablets.

I have one Google account which I want to use across all devices so that the young children don't have to remember user names and passwords.

The trouble that I'm having is that not all of them are able to be logged in at once. There appears to be a limit as to how many devices can be online with this account at once. We're doing this to be able to use Google Drive so that the kids can produce work and save it into Drive.

We are finding that as tablets are booted up, already online device are logged out from Google and I have to log them in the android backend.

I'd love to get this sorted. It's for the kids!

  • An older answer in SuperUser says there is no limit, but based on what you have just experienced, this may no longer be true: superuser.com/questions/501913/…

  • Why not let them email it instead?

  • I realize that there could be privacy and hassle-related issues with setting up multiple accounts, but is there any additional reason why you haven't opted for this path?

  • The reason that I don't want to go with emailing is simply because the users of these tablets will start at 4 years old and they cannot recognise letters of the alphabet yet, and so this would be impractical.

This is as close to an answer as I can find at the moment. Looking at the site for the (soon to be launched) Google Play for Education site, one of the benefits that they mention is:

For Educators

Android tablets in the classroom

Google Play for Education brings the innovation of Android technology into classrooms. Educators can set up and deploy large numbers of devices in just minutes or hours rather than days.

...

Over-the-air delivery to student devices

After finding apps they want to use, educators can push them instantly to student devices over the air. They can send the apps to individuals or groups of any size, across classrooms, schools, or even districts.

(My emphasis, from http://developer.android.com/distribute/googleplay/edu/about.html)

Which sounds promising, but if you go to the Sign Up/School Interest Page it has this interesting bit of wording on the form:

30 or fewer devices

Which suggests that there's a limit somewhere around the 30 device number. Which would match up with what you're seeing. As I can't find anything else official mentioning this limit, I can't find any official advice for getting round the limit either, sorry.

  • Thanks for the really in-depth answer that you have provided here. I pride myself of keeping up with all things android/education, but this had passed me by. I really think that this is a superb move by Google and will utterly remove the issue that I have posted above. My only slight concern is whether or not this will be compatible with the devices that I have already purchased, or simply new devices purchased through this 'scheme'. I will watch this closely. Again, thanks.

The Google Play for Education Store is creating content optimised for Nexus 7 tablets. I would be amazed if this is not available for the older tablets. I have seen no dates yet for when the store will be available, but Google have an event in November and suspect it may be then (as the service was advertised for autumn). However, they are only soliciting interest from American schools, so it may not be initially available in the UK. In the meantime I would suggest maybe looking at TabPilot which will allow you to achieve what you are after as well as a lot of other useful functionality.

  • Thanks for that really helpful comment. The TabPilot software looks exactly like what we are after, but regrettably, the pricing is just too high for me and my school. I fear slightly for this company, as it would appear that Google are planning to implement most of what they are offering for free in the coming months. I guess that we'll just hold off until the UK rollout happens. Fortunately, UK rollouts are usually pretty swift, behind the USA. Thanks again.
