Facebook Login returned invalid key hash; the key hash does not match any stored key hashes:
The hash registered in the Facebook developer console was incorrect. Copying the hash displayed in the error did not work for this app, probably because Google Play had re-signed the published APK.
Download the app-signing certificate from Google Play Console and calculate its Facebook key hash:
1 | openssl dgst -sha1 -binary app-signing-certificate.der | openssl base64 |
Register the resulting value in the Facebook app settings.
