            override fun onCancel() {
                Log.d("log","facebook login cancelled")
            }

            override fun onError(error: FacebookException) {
                Log.d("log","facebook ${error.message}")
            }

            override fun onSuccess(result: LoginResult) {
               val credential = FacebookAuthProvider.getCredential(result.accessToken.token)
                    auth.signInWithCredential(credential).addOnCompleteListener(act) {task->
                        if(task.isSuccessful) {
                            Log.d("log","taskSuccess")
                            val mail = task.result.user?.email
                            val uid = task.result.user?.uid
                        } else {
                            Log.d("log","taskFail")
                            Log.d("log","${task.exception}")
                            loader.dismiss()
                        }
                    }     
            }
        })
