3. Why mobile desktop? plus
Availability
plus
Productivity
We all love our mobile devices.
Why? Because of their instant availability.
But do we use them when we need to perform a real work?
No, because we need something with larger screen, a physical keyboard and a mouse and a multi-window OS.
Why? Because this way we can be more productive.
As you can imagine combining the two experiences requires innovations in both, the OS and the mobile devices.

4. Android goes multi-window
Starting with API level 24
Pop-up view vs split screen view. Which one is less usable on the small screen?
Google adds the multi-window capability to the Android OS.
But does it solve the productivity issue?

5. Bridging the gap
"The rest" means DeX station, Galaxy S8, S8+, Note 8 devices, custom launcher
The aim is not to replace the notebooks, but provide a new experience to mobile users.

8. Get your apps ready for desktop
A desktop app vs a mobile app on the desktop
Optimize your apps for:
Extra screen space
Freely resizable activities
Mouse navigation
Physical keyboard

9. New tech, proven best practices
Support multiple screen sizes
Use dp, alternative layouts and drawables
Handle runtime configuration changes
Resizing, maximizing, docking/undocking
Be smart about onPause()
Use configuration qualifiers
<resources_name>-desk,-mdpi
DeX doesn't use any proprietary APIs!
Minimizing the app doesn’t cause a runtime configuration change.
