我正试图将java的袖珍客户安装在roid,我的服务器是我的手提电脑。 我想我和roid的机动车用java的袖珍连接手提电脑。 但是,在客户方面,我却感到有例外:“欢迎”,而我看上去是因为呼吁书状无法适当编造。 下面是供审查的我的和roid客户旁码。 是否解决了这一例外情况:

public class SimpleActivityExampleActivity extends Activity  {

/** Called when the activity is first created. */
private String usrName;
private String vendorName;
private String message;
public Socket socket;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
  }


public void submitTheForm(View view) {

    final EditText edittext1 = (EditText) findViewById(R.id.editText1);
    final EditText edittext2 = (EditText) findViewById(R.id.EditText01);
    final EditText edittext3 = (EditText) findViewById(R.id.editText2);
    usrName = edittext1.getText().toString(); 
    vendorName = edittext2.getText().toString();
    message = edittext3.getText().toString();
    message = usrName+ "," + vendorName + "," + message;

    byte[] msg = message.getBytes();
    try {
    InetAddress serverAddr = InetAddress.getByName("192.168.1.2");
        Log.d("ClientActivity", "C: Connecting...");

        socket = new Socket(serverAddr, 2200);
    socket.getOutputStream().write(msg);
    socket.getOutputStream().flush();
    } catch (UnknownHostException e) {

        Toast.makeText(SimpleActivityExampleActivity.this, "unknownhostException", Toast.LENGTH_SHORT).show();
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (SocketException e) {
        // TODO Auto-generated catch block

        Toast.makeText(SimpleActivityExampleActivity.this, "Sockexception", Toast.LENGTH_SHORT).show();
        e.printStackTrace();
    }catch (IOException e) {
        // TODO Auto-generated catch block
        //System.out.println("in IOexception for sure");
        Toast.makeText(SimpleActivityExampleActivity.this, "IOexception", Toast.LENGTH_SHORT).show();
        e.printStackTrace();
    }
    catch (Exception e){
        Toast.makeText(SimpleActivityExampleActivity.this, "Exception", Toast.LENGTH_SHORT).show();
        e.printStackTrace();
    }finally {
        if(socket != null){
            try {
                socket.close();

            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }
}
}
