JSch in android

Question

이 코드를 사용하여 서버에 연결하려고하면 NetBeans의 코드를 일반 Java 프레임으로 시도하고 응용 프로그램이 안드로이드로 전송되면 작동을 멈추게됩니다. 내가 추가해야하는 다른 것이나 코드에 문제가 있다는 것을 명시했다.

public class MainActivity extends AppCompatActivity { 

    String host; 
    String ip; 
    String password; 

    Session s; 
    int x; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
    } 
    public void onClick(View view) throws Exception { 
      EditText t1 = (EditText) findViewById(R.id.editText); 
      EditText t2 = (EditText) findViewById(R.id.editText2); 
      EditText t3 = (EditText) findViewById(R.id.editText3); 

     if (t1 != null && t2 != null && t3 != null) { 
      host = t1.getText().toString(); 
      ip = t2.getText().toString(); 
      password = t3.getText().toString(); 

      JSch jsch = new JSch(); 
      Session session = jsch.getSession(host, ip, 22); 
      session.setPassword(password); 

      // Avoid asking for key confirmation 
      Properties prop = new Properties(); 
      prop.put("StrictHostKeyChecking", "no"); 
      session.setConfig(prop); 

      session.connect(); 

      // SSH Channel 
      ChannelExec channelssh = (ChannelExec) 
      session.openChannel("exec"); 
      ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
      channelssh.setOutputStream(baos); 

      // Execute command 
      channelssh.setCommand("ls"); 
      channelssh.connect(); 
      channelssh.disconnect(); 
     } 
     else { 
      Toast.makeText(MainActivity.this, "Invaild Input", Toast.LENGTH_LONG).show(); 
     } 
    } 
}
