@SuppressLint("SetJavaScriptEnabled")
    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        BleDebugLog.i(logTag, "onViewCreated-()")

        val headers = HashMap<String, String>()
        headers["Authorization"] = App.prefs.getString("token", "no token")

        binding.webView.apply {
            loadUrl("$BASE_URL/test/activityListWebView", headers)
            webViewClient = WebViewClient() // 새창 막기
        }
    }
