Any one got this type of issue after updating google policies
. I got this error after Google Play App Signing
for new apps uploading also.
You uploaded an APK 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, you should sign your APK with a new key before you upload it.
Finally I got my answer. @Niraj hints helped me first. Actually at the time of Google Play App
signing two .jks
file I used.
After creating 2nd one, this is my original keystore. Everytime I need to use this 2nd only for uploading.
Hope this will help other also for that only I posted my answer.
