You need to sign your APK with a valid key before uploading to the store. You also have to pay a $25 fee once to get registered as a Play Store developer. See more here.

When you create the certificate your app is signed with, you have to specify a start date and an expiry date.

It looks like the start date set on your certificate is in the future, so technically, your certificate is not valid. That's what this error message indicates.

How did you create the keystore? Consider creating a new one. See instructions here: https://developer.android.com/studio/publish/app-signing#generate-key
