If you're lucky enough to own more than one Android device you've probably already confronted this dilemma: how to manage multiple devices on a Google account. Basically you have a couple of options, you can either use the same account on both devices, meaning that your Google content will be mirrored on both devices, or you can create an alternative account for the secondary device and manage your connections manually. Here's how to do both.
One Google account on multiple devices
If you sign into a new device with the same Google account that you are already using elsewhere, a few things will happen: you will get emails on both devices as well as any Hangouts messages, YouTube subscriptions and other Google account preferences on both devices. The good thing about this method is that any Google Play Store purchases you may have made will also be available on both devices, so you won't have to pay for another license to install that app on a secondary device (unless, of course, you want a specific tablet version of the app). You'll also be able to keep up to date with what's happening and work from either device. The bad thing is that you may feel that all of this doubling up on notifications is annoying or is simply needlessly repeated because you only ever use your tablet for gaming, for example.
Multiple Google accounts on multiple devices
This way is still very easy, but requires a little more setup to get it working just how you want it to. Basically, you're already signed into your primary device with your main Google account, then, on the second device you Dead Trigger 2 quiet time.
Sync, backup and other account options
Both versions let you choose your sync settings on both devices, so you can still be logged in as the same Google account holder on both devices and just disable notifications (on your gaming tablet, for example). Also, simply not logging into things like Hangouts or Gmail on the secondary device is also an option. It all depends what you want your second device to be used for and how connected you want to be on both devices. If you're prone to gaming on both devices, you can simply use the same Google Play login information on both or use Facebook to sign into the games you want synced across devices. Of course, you'll also need to be careful with your sync and backup and restore options on both accounts, again depending on just how you want them both set up. It's Android, so you can get it just right with a little effort!
