configure
fun configure(onConfigureListener: OnConfigureListener, handler: Handler = Handler(Looper.getMainLooper()))
Configure authgear. This must be ran before any other methods. If configuration is successful and there was a valid user session, authgear's accessToken is non-null and the token is ready to be used.
It does local IO to retrieve the refresh token.
Therefore, it is possible that configure() could fail for some reasons.
configure() can be called more than once if it failed. Otherwise, it is NOT recommended to call it more than once.
Parameters
onConfigureListener
The listener.
handler
The handler of the thread on which the listener is called.
