This is Working Code

public static String getUrlFacebookUserAvatar(String name_or_idUser )
{
String address = "http://graph.facebook.com/"+name_or_idUser+"/picture";
URL url;
String newLocation = null;
try {
    url = new URL(address);
    HttpURLConnection.setFollowRedirects(false); //Do _not_ follow redirects!
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    newLocation = connection.getHeaderField("Location");
} catch (MalformedURLException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

return newLocation;
}


private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
    ImageView bmImage;

    public DownloadImageTask(ImageView bmImage) {
        this.bmImage = bmImage;
    }

    protected Bitmap doInBackground(String... urls) {
        String urldisplay = urls[0];
        Bitmap mIcon11 = null;
        try {
            InputStream in = new java.net.URL(urldisplay).openStream();
            mIcon11 = BitmapFactory.decodeStream(in);
        } catch (Exception e) {
            Log.e("Error", e.getMessage());
            e.printStackTrace();
        }
        return mIcon11;
    }

    protected void onPostExecute(Bitmap result) {
          bmImage.setImageBitmap(result);
     } 
    }

and call this method

    imgurl=getUrlFacebookUserAvatar("http://graph.facebook.com/100000351746269/picture?type=large");


                new DownloadImageTask((ImageView) findViewById(R.id.img_mainpage_profile))
                .execute(imgurl);

I never was able to get the profile image with a HTTP request, I used the built in Request to do it like this

Bundle b = new Bundle();
b.putString("fields", "id,name,email,picture,cover"); //only field you need it picture
Request r = Request.newMeRequest(fbSession, new Request.GraphUserCallback() {
    @Override
    public void onCompleted(GraphUser user, Response response) {

        String url = getProfileUrl(response);
        InputStream in = new URL(url).openStream();
        Bitmap image = BitmapFactory.decodeStream(in);
    }
 });
r.setParameters(b);
r.executeAndWait();

private String getProfileUrl(Response response){
    try{
        JSONObject obj = new JSONObject(response.getRawResponse());
        JSONObject JOSource = obj.optJSONObject("picture");
        JSONObject data = JOSource.getJSONObject("data");
        return data.getString("url");
    }catch(Exception e){
        e.printStackTrace();
    }
    return null;
}

you suply the bundle with the fields you want and the picture field returns JSON with the image url in it and then you just decode the stream

have you tried to use Facebook's ProfilePictureView?

It is intended to be used to insert the logged user's profile picture so basically what you want to do if I understand it well.

There is an example on how to use it in this tutorial.

I would suggest using AsyncTask

private class MyAsyncTask extends AsyncTask<String, Void, Void> {
    @Override
    protected Void doInBackground(String... strings) {
        img_value = new URL(
                    "http://graph.facebook.com/634179743325545/picture?type=large");
        mIcon1 = BitmapFactory.decodeStream(img_value
                    .openConnection().getInputStream());
        return null;
    }

     @Override
     protected void onPostExecute(Void result){
         user_img.setImageBitmap(mIcon1);
     }
}
