Are you trying to search for the folder by title name? Have you tried calling listChildren on the root folder? https://developers.google.com/android/reference/com/google/android/gms/drive/DriveResourceClient.html#listChildren(com.google.android.gms.drive.DriveFolder)

You can then go through the Metadata and look for the title (getTitle()) of the folder you are looking for.

@TejaDroid I fix it

`private DriveFolder queryFolderTree(DriveFolder parentFolder, int childLevel, List names) throws ExecutionException, InterruptedException { if (childLevel >= names.size()) { return parentFolder; }

    if (parentFolder == null) {
        return null;
    }
    DriveFolder findFolder = queryFolder(parentFolder, names.get(childLevel));
    DriveFolder result = null;
    if (findFolder != null) {
        // exist, find next or creating folder
        result = queryFolderTree(findFolder, ++childLevel, names);
    }
    return result;
}

public DriveFolder queryFolder(DriveFolder parentFolder, String folderTitle) throws ExecutionException, InterruptedException {
    DriveFolder findFolder = null;
    Task<MetadataBuffer> folder = resourceClient.listChildren(parentFolder);
    Tasks.await(folder);
    MetadataBuffer tempBuffer = folder.getResult();
    for (int i = 0; i < tempBuffer.getCount(); i++) {
        Metadata temp = tempBuffer.get(i);
        if (temp.isFolder() && temp.getTitle().equals(folderTitle)) {
            // exist
            findFolder = temp.getDriveId().asDriveFolder();
            break;
        }
    }
    tempBuffer.release();

    return findFolder;
}`
