I am uploading an image to my bucket in my google cloud storage with the following code:
File file = new File(\"test.jpg\");
HttpClient httpclie
It looks like you're doing a multipart upload of exactly 1 part, but you've specified the uploadType to be "media".
The media upload type is for the case where you are simply uploading a file. In that case, Google Cloud Storage expects the whole of the body to be the object that is being uploaded.
If you want to do a multipart upload, that's fine. For that, you should use the upload type "multipart." Multipart uploads expect two parts, where the first part is the object's metadata (permissions, custom user metadata, etc) and the second part is the data.
There's exact documentation for each type of upload type here: https://developers.google.com/api-client-library/php/guide/media_upload
My HttpClient-fu isn't very good, but I think that a "media" case would look more like this:
FileEntity entity = new FileEntity(file,
ContentType.create("text/plain", "UTF-8"));
HttpPost httppost = new HttpPost("https://www.googleapis.com/upload/storage/v1/b/imagecachebucket/o?uploadType=media&name=test.jpg&projection=full");
httppost.setEntity(entity);
