I need help in android application created in eclipse which is already live BUT it has some complication so we had recreate this project on Android studio.After complete debug testing, Now client is trying to make the new apk live by upgrading previous live apk. AND while doing this, client getting following error,

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: 52:D5:6D:B3:88:30:B7:88:3F:4D:8B:D5:37:67:FF:E1:93:7A:E9:89 ] and the certificate(s) used to sign the APK you uploaded have fingerprint(s): [ SHA1: B1:53:ED:20:41:2E:1F:0E:1F:5B:54:F3:8D:44:7C:59:AC:EE:FE:DB ------------------------------------------------------------------------ ].

  • Please reformat your question and describe what you have tried. Thank you! – creyD Dec 21 '17 at 07:58
  • Did you use different jks file for release apk? This could be the cause of above. – Danger Dec 21 '17 at 08:05

The answer is already in error description: "You must use the same certificate". Seems you generate signed apk using different from old version certificate (.jks file)
