  • Animations can be used in more places now. You can add an animation to a layout, so that elements fly in
    or fade into being instead of just suddenly appearing.
  •  
     
  • The media package has undergone some simplifications and other changes to support more formats including 
    OGG Vorbis, MIDI, XMF, iMelody, RTTL/RTX, and OTA audio file formats.
  •  
     
  • Searching is becoming a first class citizen. Don’t be surprised if you see a dedicated “search” button showing
    up on future prototypes. When the user starts a search, your application gets a chance to intercept it and offer
    search within your program and on other places on the phone, in addition to traditional web search.
  •  
     
  • Geocoding is now a standard feature. You can translate a string that has a street address or a business name
    into a longitude and latitude, and vice-versa.
  •  
     
  • Google has adopted the Builder pattern in a few more places, notably in the creation of Alert dialogs. Instead of
    having a bunch of constructors that take zillions of parameters you string method invocations together, like “a.setB
    (3).setC(5).show()”.
  •  
     
  • The new SDK has more support for instrumentation, debugging, and performance monitoring. For example
    there’s a class called InstructionCount that lets you time your routines down to the number of instructions they run.
    Other classes let you log events and view them in a new tool called traceview. You can find some screenshots
    here.
  •  
     
  • The socket library now appears to have support for Multicast, though I haven’t tried it yet.
  •  
     
  • There’s a new “touch mode” that affects how widget focus is done. The user gets into touch mode by, you
    guessed it, touching the screen, and it lasts until they press a key. See Touch Mode and Focus Handling in
    android.view.View for the nitty gritty details.
  •  
     
  • Context menus have been added. To get a context menu to show up the user can hold the select button or do
    what Google calls a “long click”, i.e., hold your finger on the screen for two seconds.
