Google has released Android version 4.0.3 into the wild, a day after 4.0.2 was released via OTA to the Galaxy Nexus devices. This new OS version brings with it a new SDK (v15), some bug fixes and optimizations for tablets and phones, and a bevy of new APIs, some of which are:
Social stream API in Contacts provider: Applications that use social stream data such as status updates and check-ins can now sync that data with each of the user’s contacts, providing items in a stream along with photos for each. This new API lets apps show users what the people they know are doing or saying, in addition to their photos and contact information.
Calendar provider enhancements. Apps can now add color to events, for easier tracking, and new attendee types and states are now available.
New camera capabilities. Apps can now check and manage video stabilization and use QVGA resolution profiles where needed.
Accessibility refinements. Improved content access for screen readers and new status and error reporting for text-to-speech engines.
Incremental improvements in graphics, database, spell-checking, Bluetooth, and more.
