I have the issue when my upgrade my expokit from SDK27 to SDK28.
After I publishing the app to PlayStore, Android user updated the app will have
“Uncaught Error: 27.0.0 is not a valid SDK version. Options are 28.0.0, UNVERSIONED.”
It only happened when the users update the app from old version.
It works fine for iOS and new user in Android App.
Some Android users try to uninstall and reinstall the app, it works fine.
Could anyone know what is the problem?
Yes. Your observation is correct.
1.5.1 is the new customer with Expokit 28 and they can directly download from Playstore and use without a problem.
1.4.1 is the old customer with Expokit 27 installed app, they try to upgrade to 1.5.1. The problem will happen.
I try to publish the new channel for the new version, but it also doesn’t work.
When I clear the data of the android in the Setting->Apps->Storage ->Clear Data, it can work!!
Do anyone know the reason why?
Is there a solution for this problem? Becoz I can’t ask my users to clear the data when upgrading.
