1IntroductionControlling the playback of a playlist on a mobile phone while driving can be dangerous. Voice activation of commands such as skip, back, replay can increase driver safety. In this project developed an Android app Autoplay to support these voice control features.Autoplay uses a backend server that receives messages from the user and builds a playlist for him.

2The serverIn the project we implemented a server using Google App Engine Storage.The server receives the device id, and a requested time duration for the playlist.The server sends back a playlist that will last long enough for the users requested duration.

3LoggingThe app sends to the serverinformation at the end of the use:Which audios did the user heard completely?Which audios did the user forwarded?Each user is identified uniquely with his device id.This information will help OutBrain adjust each user his own playlist.
