在适用于 Android 的 LinkedIn 集成中与服务提供商的通信失败

Question

我正在尝试将 LinkedIn Login 集成到我的 Android 应用程序中。我成功地集成了它，它工作正常。但奇怪的是，当我今天再次运行我的应用程序时，我收到了与服务提供商通信失败的错误。我检查了我的消费者和密钥。但是没有问题。我也没有改变我的代码。还有一件事，在收到此错误后，我创建了一个仅使用 LinkedIn 登录的不同项目。但这工作正常。在 google 和 stackoverflow 上搜索，有人说要修复日期和时间。我也这样做了..但仍然是同样的问题。如果有人有解决方案，请告诉我。这是我的 logcat 输出：

Answer 1

试试这个

在onCreate() 中的setContentView() 之后添加以下函数。

    if (android.os.Build.VERSION.SDK_INT > 9) {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
        }
