Welcome to the Android SDK!
If you've just downloaded the SDK, then continue with Installing the Android SDK.
If you're upgrading from a previously installed version, then refer to the Upgrading guide.
Once you've completed the SDK installation, you can start learning about development on the Android framework by reading the Developer's Guide. The SDK package also includes a wide variety of code samples specific to each Android platform. You can find the samples at this location:
<sdk>/platforms/android-<version>/samples/
Please note that you are currently viewing a local, offline version of the Android developer documentation. The offline documentation offers the same content and features as the online documentation, but since the search capability is network-based, it will not work while you are offline. Autocompletion for API packages and classes, also offered from the search box, is available both online and offline and loads the reference documentation for the item you select.
