Question

I upload photo to the server via the default HttpClient in Android SDK. I want to show progress in the user interface, is there a way to find out how much has been uploaded? Is it possible with HttpUrlConnection?

For me HTTPClient didn’t work. The bytes where buffered in parts and sent as total after the flush call. What worked was to sent it on socket level.

You can use the HttpMultipartClient for this (updated link on 30-10-2011):
http://code.google.com/p/rainbowlibs/source/browse/android/trunk/rainbowlibs/src/it/rainbowbreeze/libs/data/HttpMultipartClient.java?spec=svn94&r=94

Specify the amount of bytes for each part and update the progressbar in the while loop:

while (( line = reader.readLine()) != null && !headersEnd)

Call the HttpMultipartClient as folow:

HttpMultipartClient httpMultipartClient = new HttpMultipartClient("bluppr.com", "/api/order/create", 80);

FileInputStream fis = new FileInputStream(path + fileName);
httpMultipartClient.addFile(fileName, fis, fis.available());
httpMultipartClient.setRequestMethod("POST");
httpMultipartClient.send();

At the server side use:

<?php

$target_path = "uploads/";

$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['uploadedfile']['name'])." has been uploaded " .$_POST["order"]. " post";
} else{
    echo "There was an error uploading the file, please try again!";
}

?>

I used this for Bluppr Postcards, worked like a charm. If you need more info let me know.
