Dropbox large file upload

Surya K.

 

Trying to upload big files with below code.

String upload_id = dbxFiles.uploadSessionStart().finish().getSessionId();
byte[] temp = new byte[CHUNK];
int size = inputStream.available();
int cursor = 0;
while (cursor < size) {

int totalRead = 0;
if ((size - cursor) < CHUNK) {
temp = new byte[size - cursor];
totalRead = inputStream.read(temp, 0, size - cursor);
} else {
totalRead = inputStream.read(temp, 0, CHUNK);
}
dbxFiles.uploadSessionAppend(upload_id, cursor).uploadAndFinish(new ByteArrayInputStream(temp));
cursor += totalRead;
}

uploadFileMetadata = dbxFiles.uploadSessionFinish(new UploadSessionCursor(upload_id, cursor),
new CommitInfo(path, WriteMode.ADD, true, new Date(), false)).uploadAndFinish(inputStream);

 

 

But the size of uploaded files are drastically changed. Can you please help me out

When you say the size is "drastically changed," could you be more specific? What's the value of "size" and how big is the resulting upload? How big is "CHUNK"?

One quick debugging tip: try printing out the value of "totalRead" and "cursor" before each call to the API. This might help track down the issue.
