Just got my email notice for Comcast Xfinity application for Android phones. Surprisingly it didn't take Comcast long to get their Android version of their application out after the debut of the iPhone application.Why Comcast didn't include the QR code to download the application in the market I'm not sure.
Searching for Xfinity in the Android market as suggested quickly found the application.Comcast explains it all here:
After downloading it I gave it my Comcast account information and zip code. The TV listings were brought down to my phone quite quickly after selecting the cable system I'm on. The application then asked me if I'd like to synchronize it with my DVR. I had previously set this up to program my DVR from my computer. It also worked flawlessly.
Now I can schedule my TV recordings from anywhere on the planet. Thanks Comcast -perhaps I won't move away from your services quite so quickly.
