Android: cannot update my application at Play store

Question

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:

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

If any one has a solution let me know?

make sure your keystore to sign previous app version is the same keystore you used to sign the apk you want to upload in play store.

you can use command `keytool -list -keystore ` to check alias inside your keystore – hakim Oct 06 '16 at 10:58

While Updating the Application Things must be kept in mind:

Same Package name of old and new app.
Same Store Key for old and new app
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
