hashkey mismatch error android faebook app - react-native

Question

i created a react native android app. and then was using react-native-fbsdk to authenticate user using facebook..t i have registered the app in facebook developer portal and changed my manifest file and string file. when i launch the LoginManager.logInWithPermissions(['public_profile', 'email']) it authenticates and brings me to facebook, signs in and then gives me error "The key hash does not match any stored key hashes. Go to https://developers.facebook.com/docs/facebook-login/android for more information.".
i have created the hashkey with teh command in the help documenation with both the options here:
1.
keytool -exportcert -alias androiddebugkey -keystore %HOMEPATH%.android\debug.keystore | C:\Users\manshuk\Downloads\openssl-0.9.8k_X64\bin\openssl sha1 -binary | C:\Users\manshuk\Downloads\openssl-0.9.8k_X64\bin\openssl base64
and using the debug.keystore of the app itself like this:
keytool -exportcert -alias androiddebugkey -keystore android/app/debug.keystore | C:\Users\manshuk\Downloads\openssl-0.9.8k_X64\bin\openssl sha1 -binary | C:\Users\manshuk\Downloads\openssl-0.9.8k_X64\bin\openssl base64
i added the key in the app in facebook. in app setting, facebook.

Im not saying this works all the time. But, this worked for me.
First get you sha-1 (Read the code, youll have to EDIT it)
keytool -list -v -keystore "C:\Users\EDIT THIS\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android
paste that in your Command prompt.
Now copy your sha-1

Paste your sha-1 key in the "HEX STRING:"
Copy the value of Output (base64):
Now paste that in your fb developer app hash keys
Save, delete your app in your phone, re-install, run.
