How to backup and restore on Android

It is suggested that everyone backup their Android app data itself using a 3rd part backup program such as Helium. Helium lets you backup your apps and data to your SD card or cloud storage. With Helium, you can sync app data from your other Android devices– even if they are not on the same network. Set up backup schedules with Helium, and never lose data again.
