Java 尝试通过SSH连接androidTV

我在SSH连接方面有一些问题，我已经在我的androidTV（它的根目录）上启动了SSH服务器，我看到了连接，但是命令没有在设备上运行。我想在AndroidTV上运行vlc流。如果我使用腻子连接，我没有问题，但我的程序不工作。我在用jcaft

这是connect的课程

         try

                strConnectionIP, intConnectionPort);

                new Object[]{strConnectionIP, intConnectionPort, errorMessage});
         }

         return errorMessage;
      }

      private String logWarning(String warnMessage)

            InputStream commandOutput = ((com.jcraft.jsch.Channel) channel).getInputStream();
            channel.connect();
            int readByte = commandOutput.read();

            while(readByte != 0xffffffff)

      public String sendCommandWithoutResult(String command)
      {

         try

            channel.disconnect();
         }

         }

         return "+";
      }

      public void close()
      {
         sesConnection.disconnect();
      }

}

这是一个使用connect的类

public static void main(String[] args) 
{
    // TODO Auto-generated method stub
    System.out.println("sendCommand");

  
    sendTo("su \n am start -n org.videolan.vlc/org.videolan.vlc.gui.video.VideoPlayerActivity -e -a android.intent.action.VIEW -d  http://link",
            "192.168.0.105");
}

private static void sendTo(String command, String ip)
{
     String userName = "user";
     String password = "user";
     String connectionIP = ip;
     
     SSHManager instance = new SSHManager(userName, password, connectionIP,"",2222);
     String errorMessage = instance.connect();
     System.out.println(errorMessage + command + " ; " + userName +" ; "+ password +" ; "+ connectionIP);

     if(errorMessage != null)
     {
        System.out.println(errorMessage);
        //fail();
     }

     String expResult = "FILE_NAME\n";
    
     String result = instance.sendCommand(command);
     // close only after all commands are sent
     instance.close();
     System.out.println(connectionIP+" +");
     System.out.println(expResult + ": " + result+"\n");
    
}

}

这是相当模糊的。运行此代码时会发生什么情况？您是否收到任何错误或异常？程序仍在运行，没有异常和错误。但正在等待，其中“String result=instance.sendCommand（command）；”
