Bundle signed with a different key than Play expects
Android / Gradle · last reviewed 2026-11-10
The error looks like this
Your Android App Bundle is signed with the wrong key. Ensure that your App Bundle is signed with the correct signing key
Why it happens
You built with a new/other keystore. Play only accepts the registered upload key.
How to fix it
- Compare SHA-1: keytool -list -v -keystore your.keystore vs Play Console > Setup > App signing > Upload key certificate.
- Find and use the original keystore.
- If lost and you use Play App Signing: request an upload key reset in Play Console (takes a few days).
