在Android相机中上传拍摄图像的问题

Question

在我的应用程序中，我试图从设备上捕捉图像，并且想将其上传到服务器。 我下面这被张贴here

继答案是我启动相机

startBtn = (Button) findViewById(R.id.startBtn); 
startBtn.setOnClickListener(new View.OnClickListener() 
    { 
    public void onClick(View v) 
     { 
      startCamera(); 
     } 
    }); 
} 

public void startCamera() 
{   
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
    intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri); 
    startActivityForResult(intent, 0); 
} 

但之后，我捕捉，当我试图把它上传被撞坏的代码。在logcat中它显示的错误 在OnActivity结果并在doFileUpload

以下是我的代码

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) 
    { 
     switch(resultCode) 
     { 
      case 0: 
       break; 

      case -1: 
       onPhotoTaken(); 
       break; 
     } 
    } 

    protected void onPhotoTaken() 
    { 
     doFileUpload(MediaStore.EXTRA_OUTPUT); 
    } 

    private void doFileUpload(String extraOutput) 
    { 
     HttpURLConnection connection = null; 
     DataOutputStream outputStream = null; 
     DataInputStream inStream = null;   
     String urlServer = "http:XXXXXXXXXXXXXXXXXXXXXX/upload.php"; 
     String lineEnd = "\r\n"; 
     String twoHyphens = "--"; 
     String boundary = "*****"; 
     int bytesRead, bytesAvailable, bufferSize; 
     byte[] buffer; 
     int maxBufferSize = 1*1024*1024; 
     FileInputStream fileInputStream = new FileInputStream(new File(extraOutput)); 
     URL url = new URL(urlServer); 
     connection = (HttpURLConnection) url.openConnection(); 
     connection.setDoInput(true); 
     connection.setDoOutput(true); 
     connection.setUseCaches(false); 
     connection.setRequestMethod("POST"); 
     connection.setRequestProperty("Connection", "Keep-Alive"); 
     connection.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary); 
     outputStream = new 
     DataOutputStream(connection.getOutputStream()); 
     outputStream.writeBytes(twoHyphens + boundary + lineEnd); 
     outputStream.writeBytes("Content-Disposition: form-data; name=\"userfile\";filename=\"" + extraOutput +"\"" + lineEnd); 
     outputStream.writeBytes(lineEnd); 
     bytesAvailable = fileInputStream.available(); 
     bufferSize = Math.min(bytesAvailable, maxBufferSize); 
     buffer = new byte[bufferSize]; 
     bytesRead = fileInputStream.read(buffer, 0, bufferSize); 
     while (bytesRead > 0) 
     { 
      outputStream.write(buffer, 0, bufferSize); 
      bytesAvailable = fileInputStream.available(); 
      bufferSize = Math.min(bytesAvailable, maxBufferSize); 
      bytesRead = fileInputStream.read(buffer, 0, bufferSize); 
     } 
     outputStream.writeBytes(lineEnd); 
     outputStream.writeBytes(twoHyphens + boundary + twoHyphens +lineEnd); 
     int serverResponseCode = connection.getResponseCode(); 
     String serverResponseMessage = connection.getResponseMessage();  
     fileInputStream.close(); 
     outputStream.flush(); 
     outputStream.close(); 
    } 

请帮我修我的错误...... PLZ

我正在使用此代码上传图片从我的设备到服务器

protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
    Log.v("Test", "IGA"); 
    if (resultCode == RESULT_OK) { 
     if (requestCode == SELECT_PICTURE) { 
      selectedImageUri =(Uri)data.getData(); 
      AddCourtActivity.mImage.setImageURI(selectedImageUri); 
      selectedImagePath = getPath(selectedImageUri); 
      imagePath=selectedImagePath; 
      Log.v("Test","IGA "+imagePath); 
     } else if (requestCode == CAMERA_PIC_REQUEST) { 

      Bitmap thumbnail = (Bitmap) data.getExtras().get("data"); 
      selectedImageUri = data.getData(); 
      selectedImagePath = getPath(selectedImageUri); 
      imagePath=selectedImagePath; 

      Log.v("Test","IGA1 "+imagePath); 
      AddCourtActivity.mImage.setImageBitmap(thumbnail); 
     } 
    } 
    if (resultCode == RESULT_CANCELED) { 

     return; 
    } 
} 

public String getPath(Uri uri) { 
    String[] projection = { MediaStore.Images.Media.DATA }; 
    Cursor cursor = managedQuery(uri, projection, null, null, null); 
    int column_index = cursor 
      .getColumnIndexOrThrow(MediaStore.Images.Media.DATA); 
    cursor.moveToFirst(); 
    return cursor.getString(column_index); 
} 
public String getPath1(Uri uri) { 
    String[] projection = { MediaStore.Images.Media.DATA }; 
    Cursor cursor = managedQuery(uri, projection, null, null, null); 
    int column_index = cursor 
      .getColumnIndexOrThrow("userImage"/*MediaStore.Images.Media.DATA*/); 
    cursor.moveToFirst(); 
    return cursor.getString(column_index); 
} 
} 

//Use this class for upload image to server 


public class FileUploader { 

private String Tag = "UPLOADER"; 
private String urlString;// = "YOUR_ONLINE_PHP"; 
HttpURLConnection conn; 
String exsistingFileName; 
public String result; 

public String uploadImageData(String serverImageTag) {// Server image tag 
                 // may be 
                 // courtImage[] or 
                 // userImage 
    String lineEnd = "\r\n"; 
    String twoHyphens = "--"; 
    String boundary = "*****"; 
    try { 
     // ------------------ CLIENT REQUEST 

     Log.e(Tag, "Inside second Method"); 

     FileInputStream fileInputStream = new FileInputStream(new File(
       exsistingFileName)); 

     // open a URL connection to the Servlet 

     URL url = new URL(urlString); 

     // Open a HTTP connection to the URL 

     conn = (HttpURLConnection) url.openConnection(); 

     // Allow Inputs 
     conn.setDoInput(true); 

     // Allow Outputs 
     conn.setDoOutput(true); 

     // Don't use a cached copy. 
     conn.setUseCaches(false); 

     // Use a post method. 
     conn.setRequestMethod("POST"); 

     conn.setRequestProperty("Connection", "Keep-Alive"); 

     conn.setRequestProperty("Content-Type", 
       "multipart/form-data;boundary=" + boundary); 

     DataOutputStream dos = new DataOutputStream(conn.getOutputStream()); 

     dos.writeBytes(twoHyphens + boundary + lineEnd); 
     if (serverImageTag.equalsIgnoreCase("courtImage")) { 
      dos.writeBytes("Content-Disposition: post-data; name=courtImage[];filename=" 
        + exsistingFileName + "" + lineEnd); 
     } else if (serverImageTag.equalsIgnoreCase("userImage")) {

     } 
     dos.writeBytes(lineEnd); 

     Log.e(Tag, "Headers are written"); 

     // create a buffer of maximum size 

     int bytesAvailable = fileInputStream.available(); 
     int maxBufferSize = 1000; 
     // int bufferSize = Math.min(bytesAvailable, maxBufferSize); 
     byte[] buffer = new byte[bytesAvailable]; 

     // read file and write it into form... 

     int bytesRead = fileInputStream.read(buffer, 0, bytesAvailable); 

     while (bytesRead > 0) { 
      dos.write(buffer, 0, bytesAvailable); 
      bytesAvailable = fileInputStream.available(); 
      bytesAvailable = Math.min(bytesAvailable, maxBufferSize); 
      bytesRead = fileInputStream.read(buffer, 0, bytesAvailable); 
     } 

     // send multipart form data necessary after file data... 

     dos.writeBytes(lineEnd); 
     dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); 

     String serverResponseMessage = conn.getResponseMessage(); 
     BufferedReader rd = new BufferedReader(new InputStreamReader(
       conn.getInputStream())); 

     // String serverResponseCode = conn. 
     // String serverResponseMessage = conn.getResponseMessage(); 

     while ((result = rd.readLine()) != null) { 

      Log.v("result", "result " + result); 

       Login.fbResponse = result; 

     } 
     // close streams 
     Log.e(Tag, "File is written"); 
     fileInputStream.close(); 
     dos.flush(); 
     dos.close(); 
     rd.close(); 
    } catch (MalformedURLException ex) { 
     Log.e(Tag, "error: " + ex.getMessage(), ex); 
    } 

    catch (IOException ioe) { 
     Log.e(Tag, "error: " + ioe.getMessage(), ioe); 
    } 

    // Parsing has finished. 
    return result; 
} 

public FileUploader(String existingFileName, String urlString) { 

    this.exsistingFileName = existingFileName; 
    this.urlString = urlString; 

} 

只需在构造函数中传递existingFileName，urlString，然后就可以上传文件。
