Backing up App Data to the Cloud

Dependencies and prerequisites

  • Android 2.2 (API level 8) and higher

Users often invest significant time and effort creating data and setting preferences within apps. Preserving that data for users if they replace a broken device or upgrade to a new one is an important part of ensuring a great user experience.

This class covers techniques for backing up data to the cloud so that users can restore their data when recovering from a data loss (such as a factory reset) or installing your application on a new device.

It is important to note that the API for cloud backup changed with the release of Android 6.0 (API level 23). For your app to support backup both on devices running Android 6.0, and those running Android 5.1 (API level 22) and lower, you must implement both techniques that this class explains.
