How To Upload Array Of Image Files Using Multipart In Android Volley Library

I'm just beginner in Android App development. I want to upload image files using Android Volley library. I have used this helper class found somewhere in some blog.: public cla

Solution 1:

Try this code:

I had similar kind of issue i fixed using this

Uploading multiple files in array using multipart

1. Add dependecies

   compile'org.apache.httpcomponents:httpcore:4.2.4'compile'org.apache.httpcomponents:httpmime:4.2'compile'com.mcxiaoke.volley:library:1.0.19'

2.Add in gradle

    defaultConfig {
            useLibrary 'org.apache.http.legacy'
    }

3. Helper class AndroidMultiPartEntity.java

   publicclassAndroidMultiPartEntityextendsMultipartEntity
   
   {
   
       privatefinal ProgressListener listener;
   
       publicAndroidMultiPartEntity(final ProgressListener listener) {
           super();
           this.listener = listener;
       }
   
       publicAndroidMultiPartEntity(final HttpMultipartMode mode, final ProgressListener listener) {
           super(mode);
           this.listener = listener;
       }
   
       publicAndroidMultiPartEntity(HttpMultipartMode mode, final String boundary,
                                     final Charset charset, final ProgressListener listener) {
           super(mode, boundary, charset);
           this.listener = listener;
       }
   
       @OverridepublicvoidwriteTo(final OutputStream outstream)throws IOException {
           super.writeTo(newCountingOutputStream(outstream, this.listener));
       }
   
       publicinterfaceProgressListener {
           voidtransferred(long num);
       }
   
       publicstaticclassCountingOutputStreamextendsFilterOutputStream {
   
           privatefinal ProgressListener listener;
           privatelong transferred;
   
           publicCountingOutputStream(final OutputStream out,
                                       final ProgressListener listener) {
               super(out);
               this.listener = listener;
               this.transferred = 0;
           }
   
           publicvoidwrite(byte[] b, int off, int len)throws IOException {
               out.write(b, off, len);
               this.transferred += len;
               this.listener.transferred(this.transferred);
           }
   
           publicvoidwrite(int b)throws IOException {
               out.write(b);
               this.transferred++;
               this.listener.transferred(this.transferred);
           }
       }
   }
   

4. API call method

   privateclassregisterCallextendsAsyncTask<Void, Integer, String> {
   @OverrideprotectedvoidonPreExecute() {
       super.onPreExecute();
   }
   
   @OverrideprotectedvoidonProgressUpdate(Integer... progress) {
   }
   
   @Overrideprotected String doInBackground(Void... params) {
       return registerMultipartCall();
   }
   
   private String registerMultipartCall() {
       StringresponseString=null;
       HttpClienthttpclient=newDefaultHttpClient();
       HttpPosthttppost=newHttpPost("URL");  //UPLOAD URLtry {
           AndroidMultiPartEntityentity=newAndroidMultiPartEntity(newAndroidMultiPartEntity.ProgressListener() {
               @Overridepublicvoidtransferred(long num) {
               }
           });
   
           FilesourceFile=newFile(filePath);
           FilesourceFile2=newFile(filePath);
   
           entity.addPart("images[0]",  newFileBody(sourceFile));
           entity.addPart("images[1]",  newFileBody(sourceFile2));
           //Do your stuff multiple files
   
           entity.addPart("file_type", newStringBody("image");
           entity.addPart("file_form", newStringBody("post");
   
           httppost.addHeader("Accept","application/json");
           httppost.addHeader("Content-Type", "multipart/form-data");
           httppost.addHeader("Authorization", "Bearer " + sharedPreferencesManager.retreiveString(AppText.ACCESS_TOKEN));
   
   
           httppost.setEntity(entity);
   
           // Making server callHttpResponseresponse= httpclient.execute(httppost);
           HttpEntityr_entity= response.getEntity();
   
           intstatusCode= response.getStatusLine().getStatusCode();
           if (statusCode == 200) {
               // Server response
               statusCode = 200;
               responseString = EntityUtils.toString(r_entity);
           } else {
               statusCode = 200;
               responseString = "Error occurred! Http Status Code: " + statusCode;
           }
   
       } catch (ClientProtocolException e) {
           responseString = e.toString();
       } catch (IOException e) {
           responseString = e.toString();
       }
   
       return responseString;
   
   }
   
   @OverrideprotectedvoidonPostExecute(String result) {
       hideProgressDialog();
   
   }
   

   }

5.Calling Async

  new registerCall().execute();

Solution 2:

Just replace getByteData() method with this below code:

private dataPartList = ArrayList();

@OverrideprotectedMap<String, List<DataPart>> getByteDataList(){
 Map<String, List<DataPart>> params = newHashMap<>();
  params.put("yourKey","dataPartList");
    return params
}
