通过引用https://codelabs.developers.google.com/codelabs/cast-videos-android/#6，我已经在我的 android 应用程序中实现了 chrome cast。我能够成功投射视频。实验设置未更改（仅接收器应用程序 ID 设置为 DEFAULT_MEDIA_RECEIVER_APPLICATION_ID），但现在在 SessionManagerListener 回调中我收到错误 15。任何线索都会有所帮助。回调流程如下所示。
@Override
public void onSessionStarting(CastSession session) {
//able to get here
}
@Override
public void onSessionStartFailed(CastSession session, int error) {
//error =15
}
