创建Android TV应用程序以获取HDMI端口数据并将其发送到我的自定义应用程序

Question

尝试创建一个Android TV应用程序，该应用程序将从HDMI端口接收输入并将其显示到videoView中。

我已经加载了Realtek的库文件并创建了一个流服务。硬件是Realtek RTD1295

在MainFragment内部，正在创建HDMI管理器。 onStart方法如下：

@Override
public void onStart() {
    super.onStart();

    if (preferences == null) {
        preferences = PreferenceManager.getDefaultSharedPreferences(getActivity());
    }

    // halt startup if we don't have all needed permissions
    if (!checkPermissions()) {
        return;
    }

    if (hdmiSurfaceHolderCallback == null) {
        hdmiSurfaceHolderCallback = new HdmiSurfaceHolderCallback();
        surfaceHolder.addCallback(hdmiSurfaceHolderCallback);
    }

    if (hdmiHotplugReceiver == null) {
        hdmiHotplugReceiver = new HdmiHotplugReceiver();
        getActivity().registerReceiver(hdmiHotplugReceiver, new IntentFilter(HDMIRxStatus.ACTION_HDMIRX_PLUGGED));
    }

    if (checkHdmiReadyHandler == null) {
        checkHdmiReadyHandler = new Handler(new Handler.Callback() {
            @Override
            public boolean handleMessage(Message msg) {
                checkHdmiReady();
                return true;
            }
        });
    }

    if (hdmiRxManager == null) {
        hdmiRxManager = new RtkHDMIRxManager(); //Line 128 Of MainFragment
    }

    if (streamActivityReceiver == null) {
        streamActivityReceiver = new StreamActivityReceiver();
        getActivity().registerReceiver(streamActivityReceiver, new IntentFilter(STREAM_ACTIVITY_INTENT));
    }

    if (preferencesChangeListener == null) {
        preferencesChangeListener = new SharedPreferenceChangeListener();
        preferences.registerOnSharedPreferenceChangeListener(preferencesChangeListener);
    }
}

有两个问题，

1. 应用程序的首次运行始终是成功的。但是从病房的第二次起，它总是会抛出同样的错误。
2. 即使应用程序第一次运行，也从未检测到HDMI输入。

目前的发展基于this project

错误日志如下：

我也开发了这种类型的项目并且在我的情况下遇到了相同的错误，因为我使用的媒体盒不支持realtek硬件，所以检查你的盒子支持并使用Realtek支持然后你的应用程序将能够从中找到realtek lib系统
