Error while getting facebook profile picture in Android

Question

I am tryging to get the facebook profile image with the code below. I try the link that is in the log it seems fine, but in the getContent() part I get the error. Any ideas about why this is happening?

My code is:

 imgUrl = new URL("https://graph.facebook.com/" + facebookID + "/picture?type=large");
                                            System.out.println("problem 7");
                                            System.out.println(imgUrl);
                                            InputStream in = (InputStream) imgUrl.getContent();
                                            System.out.println("problem 7.5");
                                            Bitmap  bitmap = BitmapFactory.decodeStream(in);
                                            System.out.println("problem 8");

The error is as below:

Your operation is performing on main thread. You should use _Asynctask_ or Thread to overcome with this error. — Piyush, Apr 21 '16 at 13:08
I couldn't got it I am a bit new in android. So could you please give more detail? — saner, Apr 21 '16 at 13:09

You can use Thread or AsyncTask to download your image in background thread. Here is an example of doing it with thread.

Thread  thread = new Thread() {
      public void run() {

        try{
         imgUrl = new URL("https://graph.facebook.com/" + facebookID + "/picture?type=large");
                                            System.out.println("problem 7");
                                            System.out.println(imgUrl);
                                            InputStream in = (InputStream) imgUrl.getContent();
                                            System.out.println("problem 7.5");
                                            Bitmap  bitmap = BitmapFactory.decodeStream(in);
                                            System.out.println("problem 8");
        } catch (Exception e) {

        }


      }
    };
    thread.start();
  }

Hello Vivek now I am getting the error: java.lang.IllegalArgumentException: value may not be null. – saner Apr 21 '16 at 13:32
for which value is that exception for? – Vivek Mishra Apr 21 '16 at 13:34
for imgUrl.getContent() but the println(imgUrl) gives me the link in which after clicking the link I see the profile picture. – saner Apr 21 '16 at 13:35
post this stack trace in your question – Vivek Mishra Apr 21 '16 at 13:37
When you already have bitmap in run method then why you are again converting stream to image? See this line `Bitmap bitmap = BitmapFactory.decodeStream(imgUrl.openConnection().getInputStream());` – Vivek Mishra Apr 21 '16 at 13:53
I try to get the image and save it to my parse server. How should I update? – saner Apr 21 '16 at 13:58
Ok I put the upcoming part of my code into the thread part (where I save the photo into my database) and it startet to work. I guess it was because the image tried to be saved before it was decoded in the thread. Now it is working. Thank you very much Vivek. – saner Apr 21 '16 at 14:18
