Even in the midst of grand architectures designed to shift as much user data into the cloud as possible, the transient nature of mobile applications will always require that at least some user data be persisted locally on the device. This data may range from cached responses from a web service guaranteeing offline access to preferences that the user has set for specific application behaviors. Android provides a series of helpful frameworks to take the pain out of using files and databases to persist data.
