I have opted for google play app signing and i understand that google changes the signing keys for the app and I found the Sha 1 certificate but couldnt find the keyhash .
How can i get the keyhash of my released app is there a way to extract it from the certificate?
The easiest way would be to copy Facebook's error message and copy the keyhash they were expecting to get from there.
Just make sure you are using your Google Play downloaded app :)
echo "App signing key generate by google in play console" | xxd -r -p | "openssl path" base64
