Facebook profile picture request i.e. “http://graph.facebook.com/me/picture”

When I do a request for a profile picture, mine in this case I receive some kind of encoded string in my HttpResponseHandler. The code below is the request for my profile picture.

private static AsyncHttpClient client = new AsyncHttpClient();

client.get("http://graph.facebook.com/1206433/picture",  fbPictureHandler);

The code below is my handler to retrieve a response. I get the response as a string, but I am not sure what to do with this response object. I have tried converting to a byte array and writing to "file.jpg" this hasnt worked. My main question is what do I do with this response object?

private static AsyncHttpResponseHandler fbPictureHandler = new AsyncHttpResponseHandler ()        
{
@Override
public void onStart() {
Log.d(TAG,"started picture handler");
}
@Override
public void onSuccess(String response) {
        //Not sure what to do here, have been unable to do anything with this Byte   //array
    byte[] imageBackground = response.getBytes();

    }
    @Override
    public void onFailure(Throwable error) {
        Log.d(TAG, "unable to retrieve picture");
        error.printStackTrace();
    }
    @Override
    public void onFinish() {
        Log.d(TAG,"Finished picture handler");
    }
};

This is the PrintString of the response object

ANy help is greatly appreciated and hopefully this can help others.

Use the following request instead of the one that you are issuing

http://graph.facebook.com/1206433?fields=picture

This will return a JSON string to you in the following format which contains the original path to the profile image.

{
   "picture": "http://profile.ak.fbcdn.net/hprofile-ak-snc4/260615_1206433_140418666_q.jpg"
}

Parse this string to get the path of "picture" and use it in your code to get the picture.


Here is a sample request example

NOTE : http://profile.ak.fbcdn.net/hprofile-ak-snc4/260615_1206433_140418666_q.jpg is obtained by parsing the JSON string in the first step.

WebRequest request = WebRequest.Create("http://profile.ak.fbcdn.net/hprofile-ak-snc4/260615_1206433_140418666_q.jpg");
WebResponse response = request.GetResponse();
Stream stream = response.GetResponseStream();
pictureBox1.Image = Image.FromStream(stream);

This will load the image to a picture box in a windows form application.

If you need anymore help let me know.
