title: Can't get uploading or downloading progress in Google Drive Android SDK
body: <p>I am working on application where i take a backup of some user's data to Google drive and in a later time i restore them.</p>
  
  <p>The problem is that the files created and restored with no problems except that i can't see any progress, if i am uploading a large file it keep doing that in the background and can't notify the user that there is some operation happening in the background.</p>
  
  <p>here is a snippet from the method i am using </p>
  
  <pre><code>Drive.DriveApi.newDriveContents(client)
                  .setResultCallback(new ResultCallback&lt;DriveApi.DriveContentsResult&gt;() {
                      @Override
                      public void onResult(@NonNull DriveApi.DriveContentsResult driveContentsResult) {
                          final DriveContents driveContents = driveContentsResult.getDriveContents();
                          File file = new File(filesToUpload.get(0).getURI());
                          // write content to DriveContents
                          OutputStream outputStream = driveContentsResult.getDriveContents().getOutputStream();
                          try {
                              outputStream.write(FileManagerUtils.getBytes(file));
                          } catch (IOException e) {
                              e.printStackTrace();
                              NotificationManger.dismissUploadingNotification();
                              NotificationManger.showSucessNotification(getApplicationContext(), R.string.notification_uploading_success);
                          }
                          MetadataChangeSet changeSet = new MetadataChangeSet.Builder()
                                  .setTitle(obj.getFileName())
                                  .build();
                          DriveId folderID = null;
  
                          // create a file on root folder
                          Drive.DriveApi.getFolder(client, folderID)
                                  .createFile(client, changeSet, driveContents)
                                  .setResultCallback(new ResultCallbacks&lt;DriveFolder.DriveFileResult&gt;() {
                                      @Override
                                      public void onSuccess(@NonNull DriveFolder.DriveFileResult result) {
                                          if (!result.getStatus().isSuccess()) {
                                              Log.d(TAG, "Error while trying to create the file");
                                              return;
                                          }
                                          Log.d(TAG, "Created a file with content: " + result.getDriveFile().getDriveId());
                                          if (filesToUpload.size() &gt; 0) {
                                              filesToUpload.remove(0);
                                              backup();
                                          }
                                      }
  
                                      @Override
                                      public void onFailure(@NonNull Status status) {  
  
                                           // show error
                                      }
                                  });
                      }
                  });
  </code></pre>
  
  <p>The problem is that if i'am uploading 3 files, the 
  <code>Log.d(TAG,Log.d(TAG, "Created a file with content: " + result.getDriveFile().getDriveId());</code> is called very quickly after each others, and the actual files keep uploading in the background.</p>
  
  <p>So can anyone tell me how to get real status of the uploading files in the background?</p>
