Honestly, I don't have this device (I don't have a tablet period) so I can really only offer generalized advice, lol.
I did some googling and most people say that clearing cache and data for Gmail helps. Here are a couple of the threads I found: and . If none of that works, Google 'com.process.google.gapps has stopped' and there are a few more threads with more suggestions.
I'm sorry I can't be of more help, maybe someone who actually has one of these can come shed some more light on the issue
