Filters.ownedByMe doesn't work in 'Drive API for Android' (But works correctly in 'API Client Library for Java')

问题

Previously, I'm using "API Client Library for Java" to perform file search in appdata folder.

File searching code in API Client Library for Java

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;
}

It works perfectly fine for the following query string.

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

Recently, I try to migrate the code to use "Drive API for Android". I have 2 scopes for GoogleApiClient

• Drive.SCOPE_FILE
• Drive.SCOPE_APPFOLDER

File searching code in Drive API for Android

private static void searchFromGoogleDrive(GoogleApiClient googleApiClient) {
    DriveFolder driveFolder = Drive.DriveApi.getAppFolder(googleApiClient);

    Query query = new Query.Builder()
            .addFilter(Filters.and(
                Filters.contains(SearchableField.TITLE, "jstock-fe78440e-e0fe-4efb"),
                Filters.eq(SearchableField.TRASHED, false),
                Filters.ownedByMe()
            ))
            .build();

    DriveApi.MetadataBufferResult metadataBufferResult = driveFolder.queryChildren(googleApiClient, query).await();

    if (metadataBufferResult == null) {
        Log.i("CHEOK", "metadataBufferResult is null");
    } else {
        Log.i("CHEOK", "metadataBufferResult's status = " + metadataBufferResult.getStatus().isSuccess());
    }

    if (metadataBufferResult != null && metadataBufferResult.getStatus().isSuccess()) {
        MetadataBuffer metadataBuffer = null;
        try {
            metadataBuffer = metadataBufferResult.getMetadataBuffer();
            if (metadataBuffer != null ) {
                for (Metadata md : metadataBuffer) {
                    if (md == null || !md.isDataValid()) {
                        continue;
                    }

                    Log.i("CHEOK", "title = " + md.getTitle());
                }   // for
            }   // if
        } finally {
            if (metadataBuffer != null) {
                metadataBuffer.release();
            }
        }
    }

    return;
}

I realize, Filters.ownedByMe is the one which causes the problem.

Here's the different outcomes based on different Queries.

Failed

Query query = new Query.Builder()
        .addFilter(Filters.and(
            Filters.contains(SearchableField.TITLE, "jstock-fe78440e-e0fe-4efb"),
            Filters.eq(SearchableField.TRASHED, false),
            Filters.ownedByMe()
        ))
        .build();            
// metadataBufferResult's status = false

Failed

Query query = new Query.Builder()
        .addFilter(Filters.and(
            Filters.ownedByMe()
        ))
        .build();
// metadataBufferResult's status = false

Success

Query query = new Query.Builder()
        .addFilter(Filters.and(
            Filters.contains(SearchableField.TITLE, "jstock-fe78440e-e0fe-4efb"),
            Filters.eq(SearchableField.TRASHED, false)
        ))
        .build();    
// metadataBufferResult's status = true
// title = jstock-fe78440e-e0fe-4efb-881d-264a01be483c-checksum=2298926779-date=1452429908167-version=1107.zip

It seems that Filters.ownedByMe() doesn't work as correctly in Drive API for Android

Is there anything I can rectify this?
