The API levels are defined in your config.xml file. You can adjust your target, min and max levels in there.
Is this the line to add? I fouind it in the Adobe help docs.
<preference name="android-targetSdkVersion" value="26" />
I added the line to the config file and no longer get the rejection. BUT...now there is a bigger problem. There is an issue with the signing keys.
You uploaded an APK or Android App Bundle that is signed with a key that is also used to sign APKs that are delivered to users. Because you are enrolled in app signing by Google Play, you should sign your APK or Android App Bundle with a new key before you upload it.
I apparently unknowingly enrolled in Google Play app signing and can't get out of it.
I create web apps and Adobe converts them to apk files. I use a signing key created in the command line and Adobe has the key which I unlock before I request a build. I have looked at the info from page to page on Google and I can't understand what I have to do. It seems very complicated. I do not use Android Studio.
If you can give me some simple steps? I'll be reading the Google instructions again in the meantime.
Also, I'll post this under a new topic heading.
!!!! I fond a note on the forum here
Before you upload an apk you have to opt out. If you miss or if you accidently opt in you can not go back.
opt out is in: release management -> app releases -> edit release, first block: chose : "not now" !
It worked...I'm out of Google App Signing. Miracle!
