我去了三星网站并下载了媒体控制 SDK 包。当我在 Galaxy S3 Android 4.3 上使用 AllShare Cast 视频播放器时，我的智能电视（在同一网络中）出现在 AllShare Cast 列表中。
然而，
当我在根深蒂固的 Galaxy Note 2 Android 4.1.1 上使用相同的应用程序时，我的智能电视（在同一网络中）没有出现在 AllShare Cast 列表中。
代码：
public class DevicePicker extends Fragment implements OnClickListener,SmcDeviceFinder.StatusListener, SmcDeviceFinder.DeviceListener {
public interface DevicePickerResult {
void onDeviceSelected(SmcDevice device);
/**
* User clicked to disable AllShare
*/

*/

有人可以帮帮我吗？
有些应用程序甚至可以看到我的 Apple TV 设备（我的应用程序甚至无法在 AllShare Cast 列表中看到此 Apple TV 设备）
非常感谢。
