Question

我想投射从图库中选择的本地数据（图像/视频），并使用NanoHTTPD服务器在本地Web服务器上提供。提供图像的代码是：

public class MyServer extends NanoHTTPD {
    FileInputStream fileInputStream;
    private final static int PORT = 8888;


    public MyServer() throws IOException {
        super(PORT);
        start();
        System.out.println("\nRunning! Point your browers to http://localhost:8888/ \n");
    }

    public Response serve(String uri, Method method, Map<String, String> header, Map<String, String> parameters, Map<String, String> files) {
        String mediasend = " ";
        FileInputStream fis = null;
        String file;
        String answer = "";

        try {
            fis = new FileInputStream( selectedImagePath );
            mediasend= selectedImagePath.substring(selectedImagePath.lastIndexOf(".")+1);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }

        return new NanoHTTPD.Response(com.madhu.imageonserver.Server.NanoHTTPD.Response.Status.OK, mediasend, fis);
    }
}

其中selectedImagePath是：“/ storage / sdcard0 / whatsApp / WhatsApp Images / IMG-20160409-WA000.jpg”。 mediaInfo用于投射图像。

 mediaMetadata.putString(com.google.android.gms.cast.MediaMetadata.KEY_TITLE, getString(R.string.image_title));

    MediaInfo mediaInfo = new MediaInfo.Builder(ipdevice)
            .setContentType(getString(R.string.content_type_jpg))
            .setStreamType(MediaInfo.STREAM_TYPE_BUFFERED)
            .setMetadata(mediaMetadata)
            .build();

其中mediaInfo：MediaInfo @ 830029452976 ipdevice：“here”。

服务器在onCreate中启动：

    WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
    WifiInfo wifiInfo = wifiManager.getConnectionInfo();
    int ipAddress = wifiInfo.getIpAddress();
    ipdevice = String.format("http://%d.%d.%d.%d:8888", (ipAddress & 0xff), (ipAddress >> 8 & 0xff), (ipAddress >> 16 & 0xff), (ipAddress >> 24 & 0xff));

    try {
        server.start();
    } catch (IOException ioe) {
        Log.d("Httpd", "The server could not start.");
    }

但是当我尝试投射图像时没有任何反应。目的是投射图像和视频等本地数据。

有人能建议我更好的解决方案吗？
