Dropbox large file upload
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.
For my example 57 MB file uploaded with 4mb chunk become 98mb

Have you tried adding the logging I suggested? What does it reveal?
Logging I had already added before posting the issue here. Logs were fine. Everything was right. But after upload is finished and when I check the file size in Dropbox that is changed
- Steve M.
Could you share the log here (and the updated code that generates that log)?
It's hard to help you debug this without being able to see what's happening.
