android - com.android.volley.NoConnectionError 暂停应用后

Question

我正在使用 Google Volley 和 Gson 编写我的应用程序，以使用 OkHttp 作为 HTTP-Stack 与 REST 服务对话。这在大多数情况下都很好，但是当我暂停我的应用程序并返回到它时，HTTP 请求不适用于此异常:

这是随机发生的。不是每次我暂停我的应用程序。我真的不知道从哪里开始。

看来这个问题是由Android本身的一个错误引起的，应该修复!？此处描述了该问题及其修复:Android issue 24672

所以将这段代码添加到我的 OkHttp URLConnection 工厂立即解决了这个问题:

  @Override protected HttpURLConnection createConnection(URL url) throws IOException {
    HttpURLConnection connection = client.open(url);
    // Fix for bug in Android runtime(!!!):
    // https://code.google.com/p/android/issues/detail?id=24672
    connection.setRequestProperty("Accept-Encoding", "");

    return connection;
  }
