Filters.ownedByMe不'；t在'工作；Android的驱动API'；（但在'；API Java客户端库'；中正常工作）

以前，我使用“API Client Library for Java”在appdata文件夹中执行文件搜索

Java API客户端库中的文件搜索代码 最近，我尝试将代码迁移到使用“Android驱动API”。我有两个作用域用于

GoogleAppClient

• Drive.SCOPE\u文件
• Drive.SCOPE\u APPFOLDER

Android驱动器API中的文件搜索代码 我意识到，

Filters.ownedByMe

是导致问题的原因

以下是基于不同查询的不同结果

失败 失败 成功 在Android的驱动API中，

Filters.ownedByMe（）

似乎不能正常工作

有什么我可以纠正的吗？

如果没有任何其他过滤器，“ownedByMe”会返回什么？我建议将其发布在上以引起注意。没有任何其他筛选器的“ownedByMe”将在getStatus（）中返回false。isSuccess（）在我看来，您已经为“问题跟踪器”步骤做了足够的测试。为什么需要

ownedByMe

？如果您只查看appdata目录中的文件，则这些文件只能由您的应用程序创建/找到。这看起来确实像一个bug。我在Google的API问题跟踪程序上创建了一个问题：

private static void searchFromGoogleDrive(Drive drive, String qString) {
    try {
        Files.List request = drive.files().list().setQ(qString);

        do {                
            FileList fileList = request.execute();

            for (com.google.api.services.drive.model.File f : fileList.getItems()) {

                final String title = f.getTitle();

                if (title == null || f.getDownloadUrl() == null || f.getDownloadUrl().length() <= 0) {
                    continue;
                }
                ...
            }

            request.setPageToken(fileList.getNextPageToken());
        } while (request.getPageToken() != null && request.getPageToken().length() > 0);
    } catch (IOException ex) {
        log.error(null, ex);
        return;
    }
    return;
}

title contains 'jstock-fe78440e-e0fe-4efb' and trashed = false and 'appdata' in parents and 'me' in owners

            .build();

    if (metadataBufferResult == null) {

                    if (md == null || !md.isDataValid()) {
                        continue;
                    }
