Policy change to affect Facebook, other independently-updated apps
Google has updated its Play store with a small change to its developer program policies, to prevent malicious code appearing on devices. The small change now forbids applications supplied through the Google Play store from receiving updates using another process, in an effort to improve the overall security of apps provided to Android users.
The section marked Dangerous Products, a section that orders developers not to transmit malware, viruses, security vulnerabilities, and scams, has had a single line added at the end, according to The Verge. It reads "An app downloaded from Google Play may not modify, replace or update its own APK binary code using any method other than Google Play's update mechanism."
Though the extra line is a logical addition for additional security, it does affect some legitimate apps adversely. A recent change to the Facebook apps, around the time Chat Heads and Home were introduced, allows the app to check and receive updates independently of Google Play. In order to stay within the rules of the Google Play store, Facebook will need to remove this extra functionality.
