無法將圖像發送到服務器（OutOfMemoryError，android）

-2

我無法將圖像發送到服務器。我試圖這樣：我點擊按鈕，選擇圖像，然後圖像應該上傳到服務器。請給我一個教訓或教程如何將圖像發送到服務器。也許我做錯了什麼。下面我的錯誤：無法將圖像發送到服務器（OutOfMemoryError，android）

這是我的主類：

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


     button1 = (Button) findViewById(R.id.button1); 

     //get image path 
     button1.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       Intent photoPickerIntent = new Intent(Intent.ACTION_PICK); 
       photoPickerIntent.setType("image/*"); 
       final int SELECT_PHOTO = 1234; 
       startActivityForResult(photoPickerIntent, SELECT_PHOTO); 
      } 
     }); 
    } 

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) { 
     super.onActivityResult(requestCode, resultCode, imageReturnedIntent); 
     switch(requestCode) { 
     case 1234: 
      //if ok upload image 
      if(resultCode == RESULT_OK){ 
       Uri selectedImage = imageReturnedIntent.getData(); 
       String[] filePathColumn = {MediaStore.Images.Media.DATA}; 

       Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null); 
       cursor.moveToFirst(); 

       int columnIndex = cursor.getColumnIndex(filePathColumn[0]); 
       String filePath = cursor.getString(columnIndex); 
       String selectedImageName = selectedImage.getLastPathSegment(); 
       cursor.close(); 

       Bitmap yourSelectedImage = BitmapFactory.decodeFile(filePath); 


       HttpClient httpclient = new DefaultHttpClient(); 
       //working link 
       HttpPost httppost = new HttpPost("http://crm.pavlun.info/api/upload_photo"); 

       try { 
        if(yourSelectedImage != null) { 

         ByteArrayOutputStream bos = new ByteArrayOutputStream(); 
         yourSelectedImage.compress(CompressFormat.JPEG, 100, bos); 
         byte[] data = bos.toByteArray(); 
         String file = Base64.encodeToString(data, Base64.DEFAULT); 

         List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(7); 

         nameValuePairs.add(new BasicNameValuePair("image", file)); 
         httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
         httpclient.execute(httppost); 

         ResponseHandler<String> responseHandler = new BasicResponseHandler(); 
         String response = httpclient.execute(httppost, responseHandler); 

         Log.e("response", response); 
        } 

       }catch(Exception e) { 

       } 

      } 
     }

'請給我一個教訓或tutoria'。你不是第一個遇到這個問題的人。如果你谷歌這個網站，你會發現很多與解決方案類似的問題。簡短的回答不是使用Bitmap和BitmapFactory來上傳.jpg文件。只需上傳.jpg文件即可。 – greenapps
