Question

I’m trying to upload a presentation, using the google api drive, but the presentation goes incomplete some slides are blank, watching the logs this is what shows

com.google.api.client.http.HttpRequest execute: -------------- REQUEST  --------------

and this is the code that am using:

byte[] myFile = readImageData(blobKey,size);
ByteArrayContent mediaContent = new ByteArrayContent(mimeType, myFile);

Drive.Files.Insert insert = service.files().insert(body, mediaContent);
insert.getMediaHttpUploader().setChunkSize(1024 * 1024);
File file = insert.execute();

UPDATE

doing some testing, it seems the error only occurs when upload presentations with extension .pptx

is there any problem with the mimeType of that extension?

I hope someone can help me, thx in advance.

Answer 1

It seems like the resumable upload protocol is not being implemented correctly. The 308 response code indicates that only a chunk of the request has been uploaded and you should proceed with the next chunk.

Does it work correctly if you remove the following line from your code?

insert.getMediaHttpUploader().setChunkSize(1024 * 1024);
