We received an email from Google Play yesterday indicating that certain apps on certain devices were failing to launch due to an issue within Google Play. Google has resolved the issue but requires all of the affected apps to be re-released with an incremented version number. A copy of the Service Notification has been pasted below. This is strictly a Google Play issue and does not affect the other app stores (iTunes, Amazon, BN).
We have updated both Knots 3D (v2.8.1) and Knots 3D – Free Knot Edition (v1.1.1) on Google Play and they should be available shortly.
Subject: Google Play Service Notification: APK update required for your apps
Dear Google Play developer,
We have identified one or more of your applications as being affected by a recent issue in Google Play that prevents some users from launching your app. To resolve the issue, you need to publish an update as soon as possible. This will cause your users to receive an update, which will fix the issue.
The underlying cause was an error in the Google Play update logic that resulted in native libraries being incorrectly installed during updates of affected applications for users running Android 4.1 (Jellybean), who installed an update of your application between August 1 to August 5. This affects a small minority of applications, specifically non-forward-locked paid applications that use the NDK and native libraries.
No change to your application is required. Simply increment your versionCode in your Android manifest file, generate a new APK, and publish it through Google Play.
We apologize for the inconvenience this has caused you and your users. The underlying cause has now been rectified, and steps have been taken to ensure similar issues don’t arise in the future.
The Google Play team
