Android Question problem upload upgrade version apk, different SHA1 keystore

[mojako]

dear All,

we have some problem when upload new version of our APK to PlayStore.
PlayStore reject our APK because of our new APK has a different SHA1 certificate with previous version.

In the same project of B4A I create only once private key (Keystore) and never recreate it again. I don't know why it change.

then the question is how can I change the key so we can upload it again? or any other advice for our problem would be appreciate.

Thanks.
