Question

我使用的Chromecast应用已经上市了一段时间。我们开始接收报告，说明人们在启动后第一次尝试无法连接到Chromecast。直到最近我们才能重现这一点（并且只有一个设备恰好表现出这种行为）

Chromecast图标显示已连接，但该应用永远不会启动。最终，Chromecast图标显示已断开连接。我从这个设备上抓了一个logcat。

这似乎是Google Play服务中的Chromecast API中的全部内容。我们使用Amazon S3来托管和使用他们的SSL证书。看起来很奇怪，在这个初始错误之后，设备会连接起来。我无法围绕这一个缠绕我的大脑。我们的应用仅适用于Android设备，并非所有设备都会出现此行为。

Answer 1

当客户端的时钟关闭时，通常会发生“CertificateNotYetValidException”异常。也许遇到此问题的用户过去会设置其当前日期。您可以通过将设备的当前日期更改为过去来重现此操作。
