Android Question how to upload apk with certificates

[Makumbi]

 Upload failed
iam trying to upload a new apk but iam gettting this error below how can i add the certificates
You uploaded an APK that is not signed with the upload certificate. You must use the same certificate. The upload certificate has fingerprint:

[ SHA1: DD:2B:8F:AB:67:57:7C:E5:57:12:D9:88:1D:EB:A7:E7:6D:7B:8D:F5 ]

and the certificate used to sign the APK you uploaded have fingerprint:

[ SHA1: 7E:15:3C:EA:3B:AF:04:13:C7:01:3D:F7:75:B8:6D:C5:2C:B1:23:D6 ]

are you using different pcs to create the apk?
They do have different signkeys, right?

Use the same signkey on both pcs.

Did you uploaded one app compiled in DEBUG mode and the other in RELEASE?
NEVER upload DEBUG apks.

NEVER upload DEBUG apks.

i used the release mode apk that is the one i uploaded

Based on the error you DID uploaded one app and you are trying to upload a new apk for this app.

But both apks do have different sign-keys. WHY?

Are you sure both are compiled in RELEASE mode?
