Android: cannot update my application at Play store

While I am trying to to update my Application at play Store I am receiving message:

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: 89:2F:11:FE:CE:D6:CC:DF:65:E7:76:3E:DD:A7:96:4F:84:DD:BA:33 ]
and the certificate(s) used to sign the APK you uploaded have fingerprint(s):
[ SHA1: 20:26:F4:C1:DF:0F:2B:D9:46:03:FF:AB:07:B1:28:7B:9C:75:44:CC ]

I have searched everything but couldn't get a solution and I have also checked the following things:

  1. Private Key and store key for both old and new version
  2. Package Name is same for both old and new version
  3. Updated the version and name in manifest plus gradle

If any one has a solution let me know?

Solution

  • While Updating the Application Things must be kept in mind:

    1. Same Package name of old and new app.
    2. Same Store Key for old and new app
    3. Update the version name and version code of new in manifest file.

    For Android Studio:

    Go to Tools/BuildApk

    Select Choose Existing and Select path of your KeyStore.

    Enter Password

    Enter "Alias Name "

    Enter "Alias Password"

    And Select Next

    and then Select release

    and click Finish
