I'm trying to upgrade my app (developed with appinventor 1.0) on google play. I'm using the same keystore but I get the following message (sorry the ignorance, not sure it matters but for security I changed some of the keys below after SHA1:):
Upload failed
Your APK has been signed with multiple certificates. Please only sign it with one certificate and upload it again.
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: A6:D5:E5:66:34:84:B5:31:8E:8F:79:D7:2A:38:B1:54:5E:29:27:22 ]
and the certificate(s) used to sign the APK you uploaded have fingerprint(s):
[ SHA1: A6:D5:E5:66:34:84:B5:31:8E:8F:79:D7:2A:38:B1:54:5E:29:27:22,
SHA1: 0D:28:AC:88:7C:D8:FD:0C:BA:A7:46:BC:70:7E:EA:37:9F:A1:CC:84 ]
I am using jarsigner and zipalign afterwards. The first part of the SHA1 is reproduced exactly, but there is an extra SHA1 after a comma.
Any clue ?
