If your device is rooted I would suggest Titanium Backup. Just backup (app+data) the device or PC emulator which ever you designate as the source and transfer the backup file to the target device. If your goal is to sync both then I doubt you will achieve success as the target will be over written so choose wisely.
Personally I use a separate account to develop tracks with no friends but my alternate ID's. I do this on my Win7 PC using BlueStacks.
