I am developing an Android application. In my application, I am uploading file to AWS S3 bucket. I can upload the file successfully now to the s3 bucket using AWS Android SDK. But the problem is the "@" character in the filename is replaced with "%40" on the s3 Bucket.

This is my code for uploading file to S3

   public void s3credentialsProvider()

   {

      CognitoCachingCredentialsProvider cognitoCachingCredentialsProvider = new CognitoCachingCredentialsProvider(

         this.context,

         AwsUtility.COGNITO_POOL_ID,

         AwsUtility.BUCKET_REGION

      );

      createAmazonS3Client(cognitoCachingCredentialsProvider   );

   }





   public void createAmazonS3Client(CognitoCachingCredentialsProvider

                                       credentialsProvider){



      if(s3Client==null)

      {

         // Create an S3 client

         s3Client = new AmazonS3Client(credentialsProvider);



         // Set the region of your S3 bucket

         s3Client.setRegion(Region.getRegion(AwsUtility.BUCKET_REGION));

      }

   }



   public void setTransferUtility(){



      transferUtility = new TransferUtility(s3Client, context);

   }



   public CachedFile uploadFileTos3(CachedFile cachedFile)

   {



      File file = new File(Utilities.getRealPathFromUri(context, Uri.parse(String.valueOf(cachedFile.getFilePath()))));

      String fileHash = Utilities.getFileMD5Hash(file);

      cachedFile.setFileHash(fileHash);



      String extension = file.getAbsolutePath().substring(file.getAbsolutePath().lastIndexOf("."));

      String fileId = cachedFile.getEventCode() + "/" + cachedFile.getEmail().replace("%40","@") + "/" + cachedFile.getFileHash()  + extension;

      try{

         //fileId = URLEncoder.encode(fileId, "utf-8");

         TransferObserver transferObserver = transferUtility.upload(AwsUtility.BUCKET_NAME, fileId, file);

         transferObserverListener(transferObserver);

      }

      catch(Exception e)

      {



      }

      cachedFile.setFileId(fileId);



      return cachedFile;



   }



   public void transferObserverListener(TransferObserver transferObserver){



      transferObserver.setTransferListener(new TransferListener(){



         @Override

         public void onStateChanged(int id, TransferState state) {

            Log.i("SYNC_STATE", "State Change" + state);

         }



         @Override

         public void onProgressChanged(int id, long bytesCurrent, long bytesTotal) {

            int percentage = (int) (bytesCurrent/bytesTotal * 100);

            Log.i("SYNC_PROGRESS", "Progress in %" + percentage);

         }



         @Override

         public void onError(int id, Exception ex) {

            Log.e("error","error");

         }



      });

   }

I call the methods in this sequence:

s3credentialsProvide

 setTransferUtility

 uploadFileTos3

It is uploading to S3. But the problem is with the filename on S3:

TransferObserver transferObserver = transferUtility.upload(AwsUtility.BUCKET_NAME, fileId, file);

If I passed this value, "myemail@gmail.com/img-1.jpg" for the fileId, the file on the bucket became "myemail%40gmail.com/img-1.jpg". I do not want the @ character to be replaced. How can I solve the issue?
