Hi, it seems that there are problems while signing AIR apps for Google Play with the 3.7 SDK release version. Using the new developer console always lead to a certificate failure after the upload - switching to the previous console makes it work. I started a bug at the Adobe site and many people are complaining about it. Could you please check it out and vote for this bug? https://bugbase.adobe.com/index.cfm?event=bug&id=3541866
