Google has released an Android 1.5 software developer kit, giving programmers access to several new features, such as video support and a faster browser that will appear in a forthcoming version of the company's open-source mobile-phone operating system.

Android competes in the smartphone market with operating systems such as Apple's iPhone OS, Nokia's Symbian, and Microsoft's Windows Mobile. Although Google attracted many partners to participate in the Android project, called the Open Handset Alliance, so far, only Taiwanese handset maker HTC is offering models. New options are expected this year, though.

Google has said it initiated the Android project in an attempt to jump-start heavier and more sophisticated use of the internet on mobile phones. Search advertising on mobile phones is a new area of potential revenue growth for the company but Google also is eager to extend its online services such as Gmail more deeply into the mobile realm.

Among the changes users will be able to see in Android 1.5, codenamed Cupcake, are:

• Video recording and playback, and videos can be uploaded to YouTube.
• Stereo Bluetooth and auto-pairing for better Bluetooth headset support.
• A Web browser with the latest WebKit technology, including the Squirrelfish technology for faster JavaScript. The browser also includes copy-and-paste support, search within the page, the unified search and address bar that debuted in Google's Chrome browser, and faster scrolling.
• More widgets on the home screen, including a music player and picture frame, along with the current search and clock widgets.

There are changes under the hood, too, including the new Linux kernel version, 2.6.27. Android applications run at a higher level, though, using a variation of the Java technology for writing and running programs, and here there are changes too. Developers will be able to tap into several new application programming interfaces, providing easier support for a number of phone features:

• APIs for recording and playing back audio and video.
• APIs for widgets on the home screen and frameworks for various widgets.

However, Google cautioned, the APIs aren't final and could change before the final software developer kit is released, sometime toward the end of April.

Android's Xavier Ducrohet said in a blog post announcing the SDK: "I encourage you to start working with this early-look SDK, but please know that the APIs for Android 1.5 have not been finalised. The majority of the APIs are settled, but there may be some changes before the final release. As a result, it's very important that you don't release applications based on this early-look SDK, since they may not work on real devices.

"The applications you release should be built on the final Android 1.5 SDK release, which will be available around the end of this month."
