So, I got this notification today from my Facebook app. I rather like it as it seems like they are trying to take charge of their app development and updating. I wonder, though, is it pulling the app from the Google Play Store as my phone updated from their and not from within the app.
It seems that you end up sideloading the app from Facebook and not coming from the Google Play Store…
It seems that Google has now put a rule in place that will stop this from happening.
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.
Many are speculating that this move wasn’t directly related to the way Facebook applied the update, but to try and keep others from using it to upload malicious code.
