Question

I published a application in android market, now I try to upload a updated apk (version code, version name T already changed)
it gives a error that

Upload failed You uploaded an APK that is signed with a different
certificate to your previous APKs. You must use the same certificate.
Your existing APKs are signed with the certificate(s) with
fingerprint(s): SHA1:
82:FE:C4:DA:82:B3:20:2A:84:9F:26:E4:5D:6A:AF:0A:CA:91:1D:5A and the
certificate(s) used to sign the APK you uploaded have fingerprint(s):
SHA1: D2:B1:C5:7A:8A:1A:5B:FE:8C:EF:4E:3A:22:58:16:0B:89:6A:B0:AF

i need to update very soon, is anyone faced this problem or
how to resolve it.

Answer 1

You need to keep your keystore and your keys consistent, otherwise the Play Store will not accept your updated app for the same store listing.
