Help upload file 20-100mb

[Максим Б.]

Hello. I can not upload files larger than 10MB . Can someone help me ? I'm a beginner in Java. Here is my code :

DbxClient client = connect();
BufferedInputStream file = new BufferedInputStream(new ByteArrayInputStream(body));

try {
    if (body.length<8381002) {
        DbxEntry.File uploadedFile = client.uploadFile("/" + name,
                DbxWriteMode.add(), body.length, file);
    } else {
        //* How ???
    }
    return true;
} catch (Exception e){
    e.printStackTrace();
    return false;
}finally {
    file.close();
}

For larger files, you should use chunked uploading. It looks like you're using the Java SDK, so you can use the startUploadFile method, which will decide which kind of uploading to use for you:

i find it and it work 

Channel inputChannel = Channels.newChannel(file);
InputStream inputStream = null;
inputStream = Channels
        .newInputStream((ReadableByteChannel) inputChannel);
ByteBuffer buffer = ByteBuffer.allocate(3276800); //chunk size
int bytesRead = ((ReadableByteChannel) inputChannel).read(buffer);
long uploadOffset = bytesRead, offset;
String uploadId = null;
while (bytesRead != -1) {
    buffer.flip();
    byte[] data = new byte[buffer.remaining()];
    buffer.get(data);
    if (uploadId == null) {
        uploadId = client.chunkedUploadFirst(data);
    } else {
        offset = client.chunkedUploadAppend(uploadId, uploadOffset,
                data);
        while (offset != -1L) {
            uploadOffset = offset;
            offset = client.chunkedUploadAppend(uploadId,
                    uploadOffset, data);
        }
    }
    buffer.clear();
    bytesRead = ((ReadableByteChannel) inputChannel).read(buffer);
    uploadOffset += bytesRead;
}

client.chunkedUploadFinish("/"+name, DbxWriteMode.add(), uploadId);
