Android Download Progress

Question

Hi!

I want to know the progress of some download.
When I'm getting some resource from the internet, like this:

        String myFeed = request.getURI().toString();
        URL url = new URL(myFeed);
        URLConnection connection = url.openConnection();
        HttpURLConnection httpConnection = (HttpURLConnection) connection;
        int responseCode = httpConnection.getResponseCode();
        if (responseCode == HttpURLConnection.HTTP_OK) {

            InputStream in = httpConnection.getInputStream();
            // Process the input stream
        }

When "InputStream in = httpConnection.getInputStream();" is called,
all the content of the file is downloaded at once.

If I use:

        htttpResponse = httpClient.execute(httpRequestBase);

The problem is the same.

How can I detect the actual progress of the download?

Thank you all!

Answer 1

I think this has been answered here.

In a nutshell: use the "Content-Length" which should be in the header fields.

EDIT: sorry, I wasn't answering the question exactly. Basically once you know the expected total content length then you can keep track of how much data you have received and calculate the percentage complete.
