I'm creating my app with Ionic 3 and I set up a connection via facebook, but after generating my hash key and after the build, I can connect only once to Facebook..

After this, I have this message :

Invalid key hash. The key hash ..... dos not match any stored key hashes at https://developers.facebook.com/apps/.../dashboard/

My steps :

  • Create Facebook app
  • Add Android platform
  • Add the Build ID
  • Run the command :

keytool -exportcert -alias androiddebugkey -keystore %HOMEPATH%.android\debug.keystore | openssl sha1 -binary | openssl base64

  • Add Key Hash
  • Run the command :

ionic build android

I can only log in once, after my key hash is not valid

Catch and Log de Exception thrown by the plugin , it will have a Key Hash, you paste that on the Facebook Developers project console. I'm not really sure why the key hash in the environment differs from the one used on compilation.

Edit: I found something, check this out How does Ionic/Cordova generate hash key?
