Skype today announced that it is adding video calling support for 17 Android devices that run the Gingerbread iteration of Google’s mobile platform. Prior to today, mobile video calling with Skype had only been enabled on four Android devices — HTC Desire S, Sony Ericsson Xperia neo, Sony Ericsson Xperia pro and the Google Nexus S.

Users can download the updated Skype 2.1 for Android app from the Android Market or Skype.com/m or by scanning a QR code posted on the company’s blog.

Beyond the additional 17 devices, Skype said in a blog post today that most users running Android 2.2 (Froyo) and above should still be able to enable video calling in their Skype settings.

Still, those phones included in the update will see optimized performance not available to officially unsupported devices.

The 17 devices supported in version 2.1 include the following: Acer A5, HTC Desire (2.2), HTC Desire HD, HTC Evo 3D, HTC Evo 4G, HTC Flyer, HTC Incredible S, HTC Sensation, HTC Thunderbolt – Verizon (2.2) (U.S. only), LG Revolution – Verizon (2.2) (U.S. only), Samsung Droid Charge – Verizon (2.2) (U.S. only), Samsung Galaxy S, Samsung Galaxy S II, Samsung Galaxy Tab, Sony Ericsson Xperia mini pro, Sony Ericsson Xperia Play, Sony Ericsson Xperia ray.
