Controlling 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.
The server
In 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 user’s
requested duration.

Logging
The app sends to the server
information 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.

Voice Recognition
Autoplay supports advanced
voice recognition: the voice
recognition supports all the
features that allowed
in the player:
Back, forward, pause,
play, volume controlling .
The voice recognition is
easy to use and operated by
pressing a big button in the
middle of the app.
Comfort
Autoplay is comfortable to user and to the
programmers:
 Uploading new audios to the server is
easy using the Google App Engine
Storage Interface.
 Autoplay is friendly to user, looks good
and easy to use.
Workspace
 The
app is built for Android platform fits to
5.1 lollipop and later versions.
 We built the app using Android Studio
environment.
