Android Lollipop - Whats new

Notification Changes 
- responding from lock screen, 
- Ability to filter out the notifications based on priority, and/ a time based filtering of  notifications where only priority notification can get through in this time. 
- Incoming calls worn interrupt when watching or playing. => possibly a note for Softphone app, currently it takes over the screen when there is an incoming SIP call. 
- Ability to prioritise the notification from apps => Possibly we need to look at way to provide the priority for the notifications, ranking of notifications. 

Security: 
- Automatic security enabled on data stored on the device => We need to see if anything 
- SELinux security enforcement -> looks like this is user based access privileges 

Device Sharing:
- Device can be shared without sharing the data. Seems much like Desktop multi user modes or logins => We need to see how the app can be available or restricted based on multiple logins
- Screen pinning : pin the screen (not sure if possible to pin screen of an app) so that another user can access only that content 

Connectivity: 
 - improved network handoffs - continuing the VoIP calls without interruption when switching between cellular or WiFi -> Much interesting feature for P2G app 
- Power efficient scanning of BLE devices -> Something around Beacons, Wearables can be planned based on this. also BLE peripheral mode available. (e.g. An Android L device can be a Health monitor device and can transmit this data to another BLE device.)
