We recently shipped version 53 of our app to the Google Play Store. Users have updated from 52 to 53, and now many users are telling us that their data disappeared during the update. The app stores user data locally on the file system as .txt files, and also using localStorage. At present we are definitely hearing that the .txt files disappeared with the upgrade, and we are checking the tickets to learn if localStorage is also gone, not sure at the moment.
I searched the web and I see people saying that if you sign your Android .apk with a different key, this is exactly what will happen. We have not changed our signing key - we only have one key loaded into PhoneGap Build. So that leads me to ask... Could it be that PhoneGap Build had an issue in which a different key was used to sign our .apk file? We use PhoneGap Build and then we download the resulting .apk file and upload it to Google Play for publishing. The .apk file for version 53 of our app was built on Friday, November 6, 2015. Could it be that there was a problem with PhoneGap Build on that day that would have caused this?
Many thanks in advance.
