 1 | # retrofit-multiple-file-upload-with-progress
 2 | Upload multiple files with progressbar in retrofit android
 3 | 
 4 | 
 5 | ![Sample Home](https://raw.githubusercontent.com/sheetalkumar105/retrofit-multiple-file-upload-with-progress/master/sample.gif)
 6 | 
 7 | 
 8 | Retrofit does not have any function to upload multiple files files with progress callback. I have created a class  FileUploader that makes multiple files upload easy with retrofit.
 9 | 
10 | 
11 |     public void uploadFiles(){
12 |         File[] filesToUpload = new File[files.size()];
13 |         for(int i=0; i< files.size(); i++){
14 |             filesToUpload[i] = new File(files.get(i));
15 |         }
16 |         showProgress("Uploading media ...");
17 |         FileUploader fileUploader = new FileUploader();
18 |         fileUploader.uploadFiles("/", "file", filesToUpload, new FileUploader.FileUploaderCallback() {
19 |             @Override
20 |             public void onError() {
21 |                 hideProgress();
22 |             }
23 | 
24 |             @Override
25 |             public void onFinish(String[] responses) {
26 |                 hideProgress();
27 |                 for(int i=0; i< responses.length; i++){
28 |                     String str = responses[i];
29 |                     Log.e("RESPONSE "+i, responses[i]);
30 |                 }
31 |             }
32 | 
33 |             @Override
34 |             public void onProgressUpdate(int currentpercent, int totalpercent, int filenumber) {
35 |                 updateProgress(totalpercent,"Uploading file "+filenumber,"");
36 |                 Log.e("Progress Status", currentpercent+" "+totalpercent+" "+filenumber);
37 |             }
38 |         });
39 |     }
