上傳圖像在Php服務器在Android上編程

Question

我想從android上傳圖像到php服務器服務器工作都很好爲ios使用目標c，但在android我不知道如何上傳圖像。我曾嘗試下面的代碼，但服務器返回消息（圖像格式不正確或丟失的圖像文件

 ArrayList<File> imageFiles= new ArrayList<File>(); 
     for(int i=0;i<mCameraDataList.size();i++) { 
      File f = new File(getFilesDir(),"image"+i+".jpg"); 
      f.createNewFile(); 
      Bitmap bitmap = Bitmap.createScaledBitmap(
        BitmapFactory.decodeByteArray(mCameraDataList.get(i), 0, mCameraDataList.get(i).length),CommonMethods.getDeviceWidth(this), CommonMethods.getDeviceHeight(this), true); 
      ByteArrayOutputStream stream = new ByteArrayOutputStream(); 
      bitmap.compress(Bitmap.CompressFormat.JPEG, 90, stream); 
      byte[] bitmapdata = stream.toByteArray(); 
      FileOutputStream fos = new FileOutputStream(f); 
      fos.write(bitmapdata); 
      fos.flush(); 
      fos.close(); 
      imageFiles.add(f); 
     } 

    public static void postProduct(ArrayList<File> nImages) throws UnsupportedEncodingException { 
     MultipartEntityBuilder entity=MultipartEntityBuilder.create(); 
     entity.setMode(HttpMultipartMode.BROWSER_COMPATIBLE); 
     entity.addPart("authenticity",new StringBody("1")); 
     entity.addPart("brand_id",new StringBody("1")); 
     entity.addPart("cat_id",new StringBody("2")); 
     entity.addPart("color_id1",new StringBody("2")); 
     entity.addPart("color_id2",new StringBody("3")); 
     entity.addPart("condition_id",new StringBody("3")); 
     entity.addPart("description",new StringBody("Bgvv")); 
     entity.addPart(Constants.KeyValues.DEVICE_ID,new StringBody(Constants.DEVICE_ID)); 
     entity.addPart("images",new StringBody("images")); 
     entity.addPart("lon",new StringBody("74.344630")); 
     entity.addPart("lat",new StringBody("31.516762")); 
     entity.addPart("name_brand",new StringBody("2 puffs")); 
     entity.addPart("package_size",new StringBody("0")); 
     entity.addPart("selling_price", new StringBody("20")); 
     entity.addPart("title",new StringBody("My test")); 
     entity.addPart(Constants.KeyValues.UID,new StringBody(String.valueOf(CommonObjects.getUserProfile().getUid()))); 
     for(int i=0;i<nImages.size();i++) 
     { 
      File f=new File(nImages.get(i).getAbsolutePath()); 
      if(f.exists()){ 
       entity.addPart(Constants.KeyValues.IMAGES, new FileBody(f, "image/jpeg")); 
      } 
     } 
     new SetDataToServer(Constants.NetworkServiceMethods.Product.POST_PRODUCT, entity, new SetDataToServer.SetDataNotifier() { 
      @Override 
      public void onDataReceived(boolean isError, String message, JSONObject jsonObj) { 
       ArrayList<String> postProductResult =new ArrayList<String>(); 
       try { 
        Log.e("JSON",jsonObj.toString()); 
        if (!jsonObj.isNull(Constants.KeyValues.DATA)) { 
         JSONObject jsonObjectData = jsonObj.getJSONObject(Constants.KeyValues.DATA); 
//      postProductResult.add(jsonObjectData.getString(Constants.KeyValues.CON_ID)); 
//      postProductResult.add(jsonObjectData.getString(Constants.KeyValues.ORDER_ID)); 
        } 
       } catch (JSONException e) { 
        isError = true; 
        message = "Sorry! Error occurred in data parsing"; 
       } 
       productHandlerMethods.onPostProductResult(isError, message, postProductResult); 
      } 
     }).callServerToSetData(); 
    } 

任何機構可以告訴我在做什麼錯。

嘗試通過下面寫在Android的服務上傳圖片，確保圖片的路徑是在下面的代碼正確，將圖像中的SD卡：

public class MyService extends Service {
