所有使用 Volley 的请求都会出现 TimeoutError

Question

我正在尝试提出一些基本要求。然而，每个请求都会返回超时错误。我尝试了许多不同的网址。我的设备已连接到互联网。我通过 Android Studio 中的 WiFi 配对进行连接。我已授予我的应用 INTERNET 权限。我已经尝试将超时设置为 30 秒，但仍然发生：

val queue = Volley.newRequestQueue(this)
val basicRequest = StringRequest(Request.Method.GET, "https://google.com", 
    {Log.w("APP", "SUCCESS")},
    {Log.e("APP", it.stackTraceToString())})
queue.add(basicRequest)

发生了什么事？

Answer 1

当您添加INTERNET权限时，您需要从设备上完全卸载该应用程序。执行此操作并重新加载后，它连接正常。
