android에서 파일 경로를 사용하여 파일을 업로드하는 방법 파일 경로를 Base64로 변환 한 다음 JSON 배열로 변환하는 방법은 무엇입니까?

Question

I am using an Async task below to call the webservice helper. 

public class Send_reportclaim_Async extends AsyncTask<String, Void, String> { 

    private ProgressDialog Dialog; 

    @Override 
    protected void onPreExecute() { 
     Dialog = new ProgressDialog(Reportclaim.this); 
     Dialog.setMessage(Reportclaim.this.getResources().getString(
       R.string.loading)); 
     Dialog.setCancelable(false); 
     Dialog.show(); 
     // Dialog.setContentView(R.layout.progress_dialog); 
    } 

    @Override 
    protected String doInBackground(String... params) { 
     String result = ""; 
     try { 


      if (isInternetPresent) { 

       WebserviceHelper.sendreportclaimdetails(civilid, 
         imei, policynum, caseno.getText().toString(), dateloss.getText().toString(),policy_rep.getText().toString()); 
       result = "Success"; 
      } else { 
       result = "Failure"; 
      } 
     } catch (Exception e) { 
      result = "Failure"; 
      e.printStackTrace(); 

     } 



     return result; 

    } 

@Override 
    protected void onPostExecute(String result) { 

     // Toast.makeText(getApplicationContext(), "post execute", 
     // 1).show(); 

     if (result.contentEquals("Success")) { 

      if (AAAparams.sendmsg.contentEquals("Success")) { 

       //subview.setVisibility(View.INVISIBLE); 
       Toast.makeText(getApplicationContext(), 
         AAAparams.sendmsg.toString(), 1).show(); 

      } 

      else if (AAAparams.sendmsg.contentEquals("Failure")) { 
       if ((language.contentEquals("")) 
         || (language.contentEquals("en"))) { 
        // /to do 
        Toast.makeText(getApplicationContext(), "You FAILED", 1) 
          .show(); 

       } else if (language.contentEquals("ar")) { 

        // to do 
        Toast.makeText(getApplicationContext(), "You FAILED", 1) 
          .show(); 

       } 
      } 

     } else { 
      showAlert(Reportclaim.this, 
        getResources().getString(R.string.no_internet), "3"); 
     } 

     Dialog.dismiss(); 

    } 

} 

아래 주어진 WebserviceHelper 클래스. JSON 객체를 가져온 후 결과를 가져 오는 동안 디버깅 할 때 예외가 발생합니다.

public static void sendreportclaimdetails(String civil_id, String imei, 
     String polno, String caseno, String lossdate,String fileuploads) 
     throws ClientProtocolException, IOException, JSONException { 

    String result = null; 

    JSONObject jObject = null; 

    try { 

     METHOD_NAME = "/Dtls"; 

     HttpPost request = new HttpPost(URL + METHOD_NAME); 
     HttpClient httpclient = new DefaultHttpClient(); 
     List<NameValuePair> postParameters = new ArrayList<NameValuePair>(); 
     /*postParameters.add(new BasicNameValuePair("pImeiNumber", 
       BaseActivity.doEncrypt(imei)));*/ 
String[] separated = fileuploads.split(":"); 
     String policy_rep= separated[0]; 
     String reg_book=separated[1]; 
     String Dri_lic=separated[2]; 



     File file = new File(fileuploads); 
     FileBody fileboady = new FileBody(file); 



     MultipartEntity reqEntity = new MultipartEntity(); 
     // add file 

     reqEntity.addPart("pImeiNumber", new StringBody(String.valueOf(BaseActivity.doEncrypt(imei)))); 
     reqEntity.addPart("pPolNo", new StringBody(String.valueOf(polno))); 
     reqEntity.addPart("pCaseNo", new StringBody(String.valueOf(caseno))); 
     reqEntity.addPart("pLossDat:", new StringBody(String.valueOf(lossdate))); 
     reqEntity.addPart("pFileUploads", fileboady); 
     request.setEntity(reqEntity); 
     HttpResponse response = httpclient.execute(request); 

     /*postParameters.add(new BasicNameValuePair("pCivilId", civil_id)); 

     postParameters.add(new BasicNameValuePair("pPolNo:", polno)); 
     postParameters.add(new BasicNameValuePair("pCaseNo:", caseno)); 
     postParameters.add(new BasicNameValuePair("pLossDate", lossdate)); 

     postParameters.add(new BasicNameValuePair("pFileUploads", fileuploads));*/ 

     /* 
     UrlEncodedFormEntity entity = new UrlEncodedFormEntity(
       postParameters); 
     request.setEntity(entity); 
     HttpResponse response = getThreadSafeClient().execute(request);*/ 
     entityResponse = response.getEntity(); 


     result = EntityUtils.toString(entityResponse, HTTP.UTF_8); 
     //Log.e("resultttttttttttttttt", result.toString()); 
     JSONObject object = (JSONObject) new JSONTokener(result) 
       .nextValue(); 




    } catch (Exception e) { 
     e.printStackTrace(); 
     System.out.println("svfsdgdfjnhgfkjghkg"); 

    } 


} 

문자열 pol_rep는 reg_book는 dri_lic는 JSON 배열 후 BASE 64로 변환하고 uploaded.How 될 파일의 ​​경로를 포함한다.

서버에 파일 및 매개 변수를 보내기위한 사용 MultipartEntity :

HttpClient httpclient = new DefaultHttpClient(); 
HttpPost request = new HttpPost(URL + METHOD_NAME); 
File file = new File(fileuploads); 
FileBody fileboady = new FileBody(file); 
MultipartEntity reqEntity = new MultipartEntity(); 
// add file 
reqEntity.addPart("uploadedfile", fileboady); 
// add JSON String 
reqEntity.addPart("CaseNo:", new StringBody(String.valueOf(caseno))); 
reqEntity.addPart("LossDate:", new StringBody(String.valueOf(lossdate))); 
request.setEntity(reqEntity); 
HttpResponse response = httpclient.execute(request);
