New SDK based on cupcake branch; features multiple platform versions
Google has released an 'early-look' at the latest version of its Android SDK.
Version 1.5 is based on the cupcake branch soon to hit Android phones, featuring home screen widgets, an on-screen keyboard, live folders and speech recognition.
The SDK's structure itself has also changed: from now on, SDK releases will include multiple versions of the Android platform, meaning that developers can target different platform versions within the same SDK. It also adds support for SDK add-ons, which can be released by OEMs, carriers or other providers.
