Question

My goal for an app is to be able to write some information in an edit text box and click a button, when I click that button I want a QR Code to be made with all the information I have writen out. How I have this envisioned in my head right now is using zxing. However I dont know how to do apart of it. I need to know how to send some information to the internet then return what was printed. So with the zxing I know that I am able to write out a QR Code very easily by editing a url. (http://chart.apis.google.com/chart?cht=qr&chs=350×350&chld=L&choe=UTF-8&chl=Hello+My+Name+Is+Michael) and I can do that all fine but once I have the url that is needed how can I make my app send that url to the internet copy the QR Code and send me back the image? Is this even possible? I would like to hear your feed back on this, thanks.

Once you have the url, you should create a Bitmap and do the request to Google. You can do it in this way:

    BitmapFactory.Options bmOptions;
    bmOptions = new BitmapFactory.Options();
    bmOptions.inSampleSize = 1;
    Bitmap bm = LoadImage(image_URL, bmOptions);

.....

private Bitmap LoadImage(String URL, BitmapFactory.Options options)
{       
    Bitmap bitmap = null;
    InputStream in = null;       
    try {
        in = OpenHttpConnection(URL);
        bitmap = BitmapFactory.decodeStream(in, null, options);
        in.close();
        } catch (IOException e1) {
        /*ERROR DO SOMETHING ERROR*/
        }
    return bitmap;               
}

I hope it’s usuful for you.
