The Android SDK has the tools, sample code, and docs you need to create great apps.
HereŽs an overview of the steps you must follow to set up the Android SDK:
Prepare your development computer and ensure it meets the system requirements.
Install the SDK starter package.

Add Android platforms and other components to your SDK.
