Public Methods

public abstract void addIdTokenListener (IdTokenListener listener)

Parameters
listener represents the IdTokenListener that should be notified when the user state changes.

public abstract Task<GetTokenResult> getAccessToken (boolean forceRefresh)

Fetches a valid STS Token.

Parameters
forceRefresh force refreshes the token. Should only be set to true if the token is invalidated out of band.
Returns

Returns a string used to uniquely identify a signed-in user in a Firebase project's user database.

This identifier is opaque and does not correspond necessarily to the user's email address or any other field.

Returns
  • the string representation of the uid. Returns null if FirebaseAuth is not added to the Firebase project, or if there is not a currently signed-in user.

public abstract void removeIdTokenListener (IdTokenListener listenerToRemove)

Removes an IdTokenListener from the list of interested listeners.

Parameters
listenerToRemove represents the instance of IdTokenListener to be removed.
