Filters.ownedByMe does not work in the "Drive API for Android" (but works correctly in the "Client API library for Java")

Question

I used to use the Client API Library for Java to search for files in the appdata folder.

File Search Code in the Java API Client Library

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 great for the next query line.

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

Recently, I am trying to port the code to use the "Drive API for Android". I have 2 areas for GoogleApiClient

• Drive.SCOPE_FILE
• Drive.SCOPE_APPFOLDER

File Search Code in the Android API Driver

 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 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 understand Filters.ownedByMe is what causes the problem.

Here are different results based on different queries.

Mistake

 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 status = false 

Mistake

 Query query = new Query.Builder() .addFilter(Filters.and( Filters.ownedByMe() )) .build(); // metadataBufferResult 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 status = true // title = jstock-fe78440e-e0fe-4efb-881d-264a01be483c-checksum=2298926779-date=1452429908167-version=1107.zip 

Filters.ownedByMe() doesn't seem to work correctly in Drive API for Android

Is there anything I can fix?
