서버로 파일을 업로드하는 중 오류가 발생했습니다. Java

Question

파일을 서버로 보내는 응용 프로그램을 만들려고합니다. 응용 프로그램은 하나의 단추로 구성되며 클릭하면 파일을 서버에 업로드합니다. 여기에 지금까지 가지고있는 코드는 다음과 같습니다

public class MainActivity extends Activity implements OnClickListener { 
final String TAG = "sendButton"; 
final String TAG2 = "messageButton"; 
TextView messageText; 
Button uploadButton; 
int serverResponseCode = 0; 
String result = null; 
String url = "http://192.168.1.18"; 
File file = new File("example.txt"); 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    // findViewById(R.id.button2).setOnClickListener(this); 
    //findViewById(R.id.button2).setOnClickListener(this); 


    setupsendMessage(); 
    //setupmessageButton(); 
    uploadButton = (Button)findViewById(R.id.button1); 
    messageText = (TextView)findViewById(R.id.button2); 
} 




private void setupsendMessage() { 
// do something when the button is pressed 
// 
Button sendButton = (Button) findViewById(R.id.button1); 

sendButton.setOnClickListener(new View.OnClickListener(){ 

    @Override 
    public void onClick(View v) { 

     try { 

     HttpClient client = new DefaultHttpClient(); 
     HttpPost post = new HttpPost(url); 
     MultipartEntityBuilder builder = MultipartEntityBuilder.create(); 
     builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE); 






     FileBody fileBody = new FileBody(file); 
     builder.addPart("file", fileBody); 
     final HttpEntity yourEntity = builder.build(); 
     post.setEntity(yourEntity); 
     HttpResponse response = client.execute(post); 
     HttpEntity httpEntity = response.getEntity(); 
     result = EntityUtils.toString(httpEntity); 
     Log.v("result", result); 
    } 
    catch(Exception e) 
    { 
     e.printStackTrace();} 
     Log.i(TAG, "File Sent to Server"); 
     Toast.makeText(MainActivity.this, "File Sent to Server", Toast.LENGTH_LONG).show(); 

    } 


     }); 



    }; 

내가 응용 프로그램의 모든 것이 잘 나타나는 코드를 실행,하지만 난 버튼 아무것도 누르지 때 발생 내가 추적에 오류가
