Adaptation and Context
Context
Audio Manager provides access to volume and ringer mode control. But maximum
and minimum value of audio is managed differently by different manufacturer. It is
difficult to send same sound profile to different handset.
Adaptation
Maintained same sound profile for multiple devices
STREAM_NOTIFICATION,
STREAM_ALARM,
STREAM_MUSIC,
STREAM_RING,
STREAM_SYSTEM,
STREAM_VOICE_CALL
Adapted internal logic to provide volume compatibility in different
devices
Multi level min/max range for different audio service

Adaptation and Context
Context
Most of the scanner application handle scanning operations in different window.
Like different tab or drawer for different scanning context.
Adaptation
Unified scanning operation
Provide floating menu for all scanning job
Application logic will differentiate data
According to scanned data, contextual operation will be provided
User notification for executing task
Pop up menu for further user interaction

Things we learned QR Gossip
Complete Application Design
This is our first android application design experience
We are planning to upload this application in Google Play Store
We maintained same design language in full application
Android Permissions
To maintain security for the system and users,
Android requires apps to request permission before
the apps can use certain system data.
We learned how to ask for permission gracefully and
Implement the requested permission.
