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。我成功地投了视频。实验设置不会更改（只有Receiver Application 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
}
logcat的
