file-transfer

I am attempting to record audio on an iPhone using PhoneGap, then send that audio to a server. I am using PhoneGaps Media APIs to make the recording, then the PhoneGap file transfer API to send the file to the server. I am able to make the recording just fine, and playing it back works perfectly. When I try to send it to the server, however, the recording shows up on the server but it says the file is 0k big. I've done fairly extensive searching on this issue and found others that have had this problem. For example: https://groups.google.com/forum/#!topic/phonegap/zjzSs6JVokE function win(r) {

I am struggling with file transfer in android.I am using smack 4.1 to connect to openfire server.

I have a 17.7GB file on S3. It was generated as the output of a Hive query, and it isn't compressed. I know that by compressing it, it'll be about 2.2GB (gzip). How can I download this file locally as quickly as possible when transfer is the bottleneck (250kB/s). I've not found any straightforward way to compress the file on S3, or enable compression on transfer in s3cmd, boto, or related tools. Michel Feldheim S3 does not support stream compression nor is it possible to compress the uploaded file remotely. If this is a one-time process I suggest downloading it to a EC2 machine in the same

I've written a program in Java to use chunking to download large files over http. Everything is working fine but I'd like to add a progress bar which I can't do unless I get the total length of the file. Is there any way to do this? If the server provides a Content-Length header field, then that's easy. If it doesn't, then you're out of luck. Reasonable server implementations provide Content-Length when the content is static and has a known size. If the content is dynamically generated, then it's impossible to know the length a priori , at least without making two passes through the data. 来源：

I achieved to transfer data between two android phones using WebRTC's DataChannel : On one side, I send the data: boolean isBinaryFile = false; File file = new File(path); // let's assume path is a .whatever file's path (txt, jpg, pdf..) ByteBuffer byteBuffer = ByteBuffer.wrap(convertFileToByteArray(file)); DataChannel.Buffer buf = new DataChannel.Buffer(byteBuffer, isBinaryFile); dataChannel.send(buf); On the other side, this callback should be called regardless of isBinaryFile value : public void onMessage( final DataChannel.Buffer buffer ){ Log.e(TAG, "Incomming file on DataChannel");
