Package Name: Android.service.dreams class Name: Dream Service Dreamservice

Extend This class to implement a custom dream (available to the user as a "daydream").

Dreams was interactive Screensavers launched when a charging device was idle, or docked in a desk dock. Dreams provide another modality for apps-express themselves, tailored for a exhibition/lean-back experience.

Inherit this class to implement a custom dream (the user can "Daydream").

A dream is an interactive screen saver that starts charging when the device is idle, or when the docking station is idle. The dream provides another form of expression for the application to express itself, designed for the exhibition/nostalgia.

Plainly, it's like a PC screensaver, and Andy Rubin is teasing you. ^_
