I already made my code, uploaded it to Google Console and the APK is as draft. I made the instructions to turn the draft into publication through the version creation screen, complete the frames and saved. When clicking the Review button, the following error occurs, which is not documented anywhere: You must add a new APK or disable an existing one to create a new version.
Update: I used the upload button, where it is written 'Find files' and pointed to my APK type 'release', but the error message is 'Sending failed You uploaded an APK with an invalid signature. Learn more about subscriptions. apksigner error: ERROR: JAR_SIG_NO_SIGNATURES: In JAR Signatures'
After hours of searching, with the help of others because Google does not make too much of its collaborators to give simple tips of use, was solved my problem: just, when generating APK release type, mark in Signature Versions in Android Studio, V1 and V2 and not only V2, as I had done. And for other tips, it doesn’t look good to have passwords with different digits of letters.
