无效的应用ID-chromecast

Question

我正在调整Google Cast代码（此处提供的代码）。

我已经完成了整个工作空间的设置，但是，当尝试在Android手机上运行示例应用程序时，出现以下错误。

我刚刚将软件包名称指定为应用程序ID。我从哪里获得应用程序ID？我应该在Google注册以获得应用程序ID吗？它是如何工作的？

Answer 1

最好的方法是创建自己的接收器（样式媒体接收器）。注册时，您会获得一个应用程序ID；建议您访问Cast开发人员网站，并熟悉Chromecast及其工作方式。获取应用ID后，您需要将其插入到YOUR_APP_ID字符串所在的res / values / string.xml中。

Answer 2

去掉引号：

- CastMediaControlIntent.categoryForCast("CastMediaControlIntent.DEFAULT_MEDIA_RECEIVER_APPLICATION_ID")
+ CastMediaControlIntent.categoryForCast(CastMediaControlIntent.DEFAULT_MEDIA_RECEIVER_APPLICATION_ID)
