I am developing an app that includes Facebook Login. Everything working fine in Development mode. But after publishing my app on the Play store. I encountered an error saying: "invalid key hash facebook android does not match any stored" Thanks.

Error is telling you that you have not added the signed key hash, which is generated when your app is published on the Play store, to your Facebook app yet. Steps: Check if the release key hash is added to your Facebook app.

1. If not, generate your release key hash by using this command: keytool -exportcert -alias -keystore | openssl sha1 -binary | openssl base64

2. Add that key hash to the Basic Settings of the Facebook app.

3. Since you have published your app, go to the Play store console -> Setup -> App Integrity.

4. Copy the SHA-1 certificate fingerprint from the App signing key certificate section.

5. Then visit the below link, paste the key hash to generate the signed key hash.

6. Copy that signed key enter image description herehash and paste it to the Basic Settings of your Facebook app.
