Finalmente possiamo dire che Donut ha avuto veramente una vita molto breve, l'SDK 2.0 infatti è già disponibile!

Prima cosa che viene risaltata è l'aggiunta di nuove risoluzioni video (ora 6, in donut 4):

• QVGA (240x320, low density, small screen)
• WQVGA (240x400, low density, normal screen)
• FWQVGA (240x432, low density, normal screen)
• HVGA (320x480, medium density, normal screen)
• WVGA800 (480x800, high density, normal screen)
• WVGA854 (480x854 high density, normal screen)

Le altre fondamentali introduzioni sono:

Bluetooth

• Connect to a remote device using RFCOMM and send/receive data
• Advertise RFCOMM services and listen for incoming RFCOMM connection

Contatti

• New contacts APIs that allow for data from multiple accounts
• New Quick Contact framework APIs

Camera

• New parameters for color effect, scene mode, flash mode, focus mode, white balance, rotation, and other settings.
• New ZoomCallback interface to perform actions when the zoom level has changed.

Media

• MediaScanner now generates thumbnails for all images when they are inserted into MediaStore.
• New Thumbnail API for retrieving image and video thumbnails on demand.

Altri Framework

• New system themes in android.R.style to easily display activities on top of the current system wallpaper or keep the previous activity visible in the background.
• New WallpaperManager API replaces and extends the wallpaper APIs that were previously in Context, to allow applications to request and set the system wallpaper.
• New Service APIs to help applications correctly handle Service life-cycle, in particular low memory situations where a Service may be killed while it is running.
  • Service.setForeground() has been deprecated and now effectively performs no operation. This is replaced with a new API, startForeground(), that helps (and requires) associating an ongoing notification with the foreground state.
• MotionEvent can now report simultaneous-touch information for devices that support it. Up to three pointers can be tracked simultaneously.
• WindowManager.LayoutParams has new constants that allow a window to wake up the screen when it is displayed and show the window even if the screen is locked. This allows applications to more cleanly implement things like alarm clocks that should wake the device.

Avete capito bene, finalmente invio e ricezione di dati tramite Bluetooth e come già si sapeva sincronizzazione di account multipli!
