11. Different Version Of Android

12. Gingerbread Gingerbread -- Android 2.3 -- despite being a "dot" release. actually brought some fairly major changes to the Android platform Cosmetically, nothing changed that much. The notification bar at the top of the screen went black, and the signal strength and battery indicators turned green. Many had been hoping Gingerbread would contain the handiwork of MatiasDuarte, who led Palm's webO SUI and now is user experience director for Android.m.

Challenges • CPU typically runs 500-600 Mhz. • RAM available to an App may only be a few megabytes • Disk (flash) access is very slow • Lifecycle - apps must pause/quit often, and restore to give the illusion that they are always running • UI design *typical screen may be HVGA (320x480) *may be in portrait or landscape *very high DPI - small text may not be readable *touch resolution is very low (~25 pixel) • Network access may be slow and (very) intermittent

19. Opportunities • 100s of millions of mobile phone users • Very high growth, esp. in Asia • Wild wild west" of application development • no dominant 3rd party developers.... Yet • what will the killer app categories be? • what does it mean to have any app + the internet in your pocket? • You can develop for it today!
