我正在尝试将LinkedIn登录集成到我的Android应用中。我成功整合了它，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，我正在与服务提供商进行通信失败错误。我检查了我的消费者和密钥。但没有问题。我也没有改变我的代码。还有一件事，在收到此错误后，我创建了一个只有LinkedIn登录的不同项目。但这很好。搜索谷歌和stackoverflow，一些人说要修复日期和时间。我也做了..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：

答案 0 :(得分：2)
试试这个
在setContentView() onCreate()之后添加以下功能。
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
