Update (2011-06-27): Google has finally released an official Available in Android Market badge.
If you’re an app developer you’re probably familiar with the Available on the iTunes App Store badge below.
Since there’s no official Android Market badge yet we decided to create our own and offer it to all Android developers under a Creative Commons license.
You can use the image above by saving it and including it in your website (hotlinking is not recommended) or download the source file and modify it at your leisure.
