android - 无效的应用程序 ID - chromecast

Question

我正在调整 Google Cast 代码，即提供的代码 here .

我已完成整个工作空间设置，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？我应该向 Google 注册以获得应用程序 ID 吗？它是如何工作的？

最好的方法是创建自己的接收器(Styled Media Receiver)。当你注册它时，你会得到一个应用程序 ID；我建议你去Cast developers网站并熟悉 Chromecast 及其工作原理。获得 App Id 后，您需要将其插入到 YOUR_APP_ID 字符串所在的 res/values/string.xml 中。
