Android Question Firebase facebook auth, hash error

[Shay]

when clicking sign with basebook, I am getting my account, clicking "Continue as <my name>"
getting error on ide:

Facebook error: SERVER_ERROR: [code] 1349195 [message]: The key hash does not match any stored key hashes. Go to https://developers.facebook.com/docs/facebook-login/android for more information. [extra]:

I created hash using keytool, and put the hash key on both firebase - facebook - app secrect
and on facebook - setting, basic, key hashes

I had mistake, the app secret on firebase is the app secret from facebook page,
but still I have same issue...
is there a place to put the hash key from facebook page in firebase or in the app?

I followed this:
https://stackoverflow.com/questions/54680955/sign-in-with-facebook-error-code-1349195-ionic
and it is working, but I don't understand why it generate different hash key
this is the command I used:
keytool -exportcert -alias b4a -keystore E:\DEV\Android\BPLic.keystore | e:\dev\openssl\bin\openssl sha1 -binary | e:\dev\openssl\bin\openssl base64

where BPLic.keystore is my B4A certificate

It happened to me too. When you click on Facebook Sign in button it will popup a window and show an error message in red. Which will contain the correct app hash. Just put that in the facebook app setting page.
