My app is already in the google play store. Upon trying to upload an updated version APK, I received this message:
“When you upload an APK, it needs to meet Google Play’s target API level requirements. Both new apps and app updates must target at least Android 9 (API level 28).”
Yes, I am having the same issue. Google required the Level 29 on August 3rd and it looks like the build tool on Adalo outputs the file with the previous version
For first time apps to the PlayStore the API Level 29 is required as of August 3, for updating apps the update must be complete by Nov. This update has taken longer than we anticipated as it requires updating a few other things and we want to thoroughly test so that it’s a smooth process for all users. We hope to have this complete today. If you are submitting and update app it should allow you to continue moving forward.
