Google Drive API, Meta-Data - google-drive-api

Question

I am uploading documents to Google Drive successfully but my meta-data does not appear to be getting back to me correctly.
protected File insertFile(Drive service, List<String> parentIds, com.google.drive.FileContent fileContent, File googleFile)throws IOException {
// Set the parent folder.
if (parentIds != null && parentIds.size() > 0) {
List<ParentReference> parentReferences = new ArrayList<ParentReference>();
for (String parentId : parentIds ){
parentReferences.add(new ParentReference().setId(parentId));
}
googleFile.setParents( parentReferences );
}
try {
googleFile = service.files().insert(googleFile, fileContent).execute();
// Uncomment the following line to print the File ID.
System.out.println("File ID: " + googleFile.getId());
return googleFile;
}
catch (IOException e) {
System.out.println("An error occured: " + e);
return null;
}
}
Above is my insert statement, below is what I am sending as details about the document.
{description=XXXXXXX Invoice, fileExtension=pdf,
indexableText={text=XXXXXXX Invoice}, labels={restricted=false},
mimeType=application/pdf, parents=[{id=0B_owsnWRsIy7S1VsWG1vNTYzM1k}],
properties=[{key=DocumentType, value=11}], title=XXXXXXX Invoice}
When I do a get for that same document using this code
protected InputStream downloadFile(Drive service, File file)throws IOException {
if (file.getDownloadUrl() != null && file.getDownloadUrl().length() > 0) {
HttpResponse resp =
service.getRequestFactory().buildGetRequest(new GenericUrl(file.getDownloadUrl()))
.execute();
return resp.getContent();
}
else {
// The file doesn't have any content stored on Drive.
return null;
}
}
I get most of the text back minus the indexable Text and File Extension, is that correct (Do not want to show since it contains a lot of information that is noise)?

Two separate issues here.
1) fileExtension is a read-only field so it is being ignored. When retrieving the information, it is derived from the original title/filename. Since your title doesn't include ".pdf" it is being set to empty.
2) indexableText is write-only in we don't allow you to retrieve it once set; it is only used by the drive backend to service search queries.
You can read more on the different metadata properties of the file resource in our documentation.
