Hey Android developers—if you've visited the online Android SDK documentation recently, you may have noticed a few changes. That's right, there's a new Resources tab, which was designed to take some of the load off the Developer's Guide. We've moved a number of existing resources to the Resources tab, including tutorials, sample code, and FAQs. We've also formalized a few of our most popular developer blog posts into technical articles; watch for more of these to appear in the future.

In addition, we just released a new batch of sample code, available now as a ZIP file download on the samples index page. And we're working on updating the way in which we distribute official sample code; more on that some other time.

The new sample code includes:

• Multiple Resolutions: a simple example showing how to use resource directory qualifiers to support multiple screen configurations and Android SDK versions.
• Wiktionary and WiktionarySimple: sample applications that illustrate how to create an interactive home screen widget.
• Contact Manager: an example on using the new ContactsContract interface to query and manipulate a user's various accounts and contact providers.
• Bluetooth Chat: a fun little demo that allows two users to have a 1 on 1 chat over Bluetooth. It demonstrates how to discover devices, initiate a connection, and transfer data.
• API Demos > App > Activity > QuickContactsDemo: a demo showing how to use the android.widget.QuickContactsBadge class, new in Android 2.0.
• API Demos > App > Activity > SetWallpaper: a demo showing how to use the new android.app.WallpaperManager class to allow users to change the system wallpaper.
• API Demos > App > Text-To-Speech: a sample using Text-To-Speech (speech synthesis) to make your application talk.
• NotePad (now with Live Folders): this sample now includes code for creating Live Folders.

We hope these new samples can be a valuable resource for learning some of the newer features in Android 1.6 and 2.0. Let us know in the android-developers Google Group if you have any questions about these new samples or about the new Resources tab.

Thanks for tuning in, and 'til next time, happy coding!
