Google drive api to get all children is not working if I dynamically pass fileId to query

I am trying google drive api to search parents of a folder. In search query i have to pass file id dynamically instead of hard coding. I tried below code. but I am getting file not found json response.

here its not taking fileId as value i think its consider as String if I hardcode the value it is working. FileList result = service.files().list().setQ("name='testfile' ").execute();

    for (com.google.api.services.drive.model.File file : result.getFiles()) {
        System.out.printf("Found file: %s (%s)\n",
            file.getName(), file.getId());

       String fileId =file.getId();

        FileList childern =  service.files().list().setQ(" + \"file.getId()\" in parents").setFields("files(id, name, modifiedTime, mimeType)").execute();

This should help.

String fileid=file.getId()

 service.files().list().setQ("'" + fileId + "'" + " in parents").setFields("files(id, name, modifiedTime, mimeType)").execute();

Make sure you have valid file.getId()

I know your question states java but the only sample of this working is in C#. Another issue is as far as i know PageStreamer.cs does not have an equivalent in the java client library.

I am hoping that C# and java are close enough that this might give you some ideas of how to get it working in Java. My java knowledge is quote basic but i may be able to help you debug it if you want to try to convert this.

try
            {
                // Initial validation.
                if (service == null)
                    throw new ArgumentNullException("service");

                // Building the initial request.
                var request = service.Files.List();

                // Applying optional parameters to the request.
                request = (FilesResource.ListRequest)SampleHelpers.ApplyOptionalParms(request, optional);

                var pageStreamer = new Google.Apis.Requests.PageStreamer<Google.Apis.Drive.v3.Data.File, FilesResource.ListRequest, Google.Apis.Drive.v3.Data.FileList, string>(
                                                   (req, token) => request.PageToken = token,
                                                   response => response.NextPageToken,
                                                   response => response.Files);

                var allFiles = new Google.Apis.Drive.v3.Data.FileList();
                allFiles.Files = new List<Google.Apis.Drive.v3.Data.File>();

                foreach (var result in pageStreamer.Fetch(request))
                {
                    allFiles.Files.Add(result);
                }

                return allFiles;
            }
            catch (Exception Ex)
            {
                throw new Exception("Request Files.List failed.", Ex);
            }
