Clash-of-clans – Can you add an old active account to a new device that has an active account already

Yes this is possible. What your friend is going to need are at least two Google accounts linked to his phone.

First, from within Clash of Clans, go into settings and connect the current village to a Google+ account. This will allow him to restore his village from any device that he signs into his Google account from.

Then in Android,go to settings -> Apps -> Clash of Clans, and 'Clear Data'. This will wipe the village off the device, but it will still be linked to the Google+ account.

Now open Clash of Clans again and get past the intro tutorial. On your iOS device, open Clash of Clans, go to Settings -> Link a Device -> This is the old device. On the Android phone, open Clash of Clans, go to settings -> Link a Device -> This is the new device. Follow the steps to link the Android phone to your village. Now connect the new village to a second Google+ account (Must be different than the first one!)

Now any time he wants to switch between the two, he just simply needs to Clear Data as explained above. After loading Clash of Clans, he will be able to sign into a Google+ account (there's now an option to do so without doing the tutorial), and restore its respective village.

I just tried this entire procedure and verified it works.

For future reference, it appears that Android phones will soon be getting user profiles. So that like Android tablets, different user profiles store different sets of user data. When this feature comes out, it would be possible to setup each village on a different user profile and just simply switch between the profiles, no clearing user data needed. Though I would always recommend linking each village to a Google+ account for safety.

Did you actually link your clan to his Google+ account (by going to settings)? It's not done automatically, and only one village can be linked to a Google+ account. If your brother later linked his village to the same Google+ account, then your village will no longer be linked to it.

The only way to get your existing village back is if it's still on your brother's Android device. If you still have access to it, you can link it to your own Google+ account or use the "Link a device" option in the settings to get it onto your own phone.

If you don't have access to the village anymore, and using the Google+ account that it was supposedly linked to doesn't load your village, then the only way to get it back is to contact Supercell directly.

You can submit a help request by sending a message from the game on your device. To send an in-game message, tap the in-game settings icon, select "Help and Feedback", and then tap "Report an Issue". That will assure we have all the necessary data to make the recovering process as quick as possible.

Please include the following information in the message, so that we can locate your village:

• Exact name of the two villages
• Exact level of the two villages
• Exact Town Hall level of the two villages
• Exact clan name of the two villages

Please note that the information is required for both the lost village, and the village that you currently have on your device.

I would recommend doing this from you brother's phone as the device information will help them locate the lost village more easily.

If for some reason you can't use the "Report an Issue" option, there's also the option to send an email to clashofclans.android@supercell.net, though it is generally recommended to use the first method if available.
