私のアプリでは、grails サーバーに画像をアップロードしようとしています。問題は、画像を base 64 形式に変換することがバックエンドで受け入れられないことです。サーバー開発者は、マルチパート形式であってはならないと言っています。
これが私のコードです：

     ArrayList<NameValuePair> nameValuePairs = new  ArrayList<NameValuePair>();
     Bitmap bitmap = BitmapFactory.decodeFile(imagePath);           

     ByteArrayOutputStream stream = new ByteArrayOutputStream();
     bitmap.compress(Bitmap.CompressFormat.PNG, 90, stream); //compress to which format you want.
     byte [] byte_arr = stream.toByteArray();
     String image_str = Base64.encodeToString(byte_arr,Base64.DEFAULT);

     nameValuePairs.add(new BasicNameValuePair("fileupload",image_str));


     nameValuePairs.add(new BasicNameValuePair("message", "trial"));

     try{
         HttpClient httpclient = new DefaultHttpClient();
         HttpPost httppost = new HttpPost(serverURL);
         httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
         HttpResponse response = httpclient.execute(httppost);
         Log.i(TAG, " http reponse is:" +response);
         convertResponseToString(response);
     }catch(Exception e){
           System.out.println("Error in http connection "+e.toString());
     }

multipartEntitiy を使用することをお勧めします。例は次のとおりです。

        HttpResponse response;
        HttpClient myClient = new DefaultHttpClient();
        HttpPost myConnection = new HttpPost(YOUR_URL_HERE);

        MultipartEntity mpEntity = new MultipartEntity(
                HttpMultipartMode.BROWSER_COMPATIBLE);

        if (Photo != null) {

            mpEntity.addPart("photo", new ByteArrayBody(Photo,
                    "YOURPHOTO.png"));
        }

        try {

            if (Photo != null) {
                myConnection.setEntity(mpEntity);
            }

            response = myClient.execute(myConnection);
        }

        catch (Exception e) {
            result.setResult(BaseID.REQUEST_DATA_MEMBER_CREATE_FAILED);
            result.setError_title("Exeption Title");
            result.setError_message("Exeption Messege");
            e.printStackTrace();
        }
