Load image from url. emulator work well but device not work

Question

I had develop a mobile apps to load image from URL path.

Here is my code.

    private Drawable LoadImageFromWebOperations(String url)
    {
        try
        {
            InputStream is = (InputStream) new URL(url).getContent();
            Drawable d = Drawable.createFromStream(is, "src name");
            return d;

        }catch (Exception e)
        {   
        System.out.println("Exc="+e);
        return null;
        }
    }

This method is work well in emulator which android API 10 but cannot work in android device. The device i use test is API 16 and 17.

Kindly look for help. Thanks.

Have you provided the internet permission ? Also make sure when you run in device you make internet connection ON. — GrIsHu, Nov 19 '13 at 08:28
First Just print your imageUrl in log while running in Device.... — Piyush, Nov 19 '13 at 08:37

Have you done this?:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

and yes, you must be connected to the internet.

LotusUNSW is right, you have to add INTERNET permission but if it's working on emulator it seems that this permission is set .

EDIT : Alternatively, you can try using this method :

(last code was a stupid copy paste without checking, available here)

Don't forget to do this in a separate thread (using AsyncTask for example)

But try this thing instead

private Bitmap getImageBitmap(String url) {
        Bitmap bm = null;
        try {
            URL aURL = new URL(url);
            URLConnection conn = aURL.openConnection();
            conn.connect();
            InputStream is = conn.getInputStream();
            BufferedInputStream bis = new BufferedInputStream(is);
            bm = BitmapFactory.decodeStream(bis);
            bis.close();
            is.close();
       } catch (IOException e) {
           Log.e(TAG, "Error getting bitmap", e);
       }
       return bm;
    }

and then

Bitmap b = getImageBitmap("http://sdsdsdsdsdsdsds");
if (b != null)
  myImageView.setImageDrawable(d);

Is it full function ? copy and closeStream is undefined in this function. — XZheng, Nov 19 '13 at 08:47

Try to move this code to a thread or AsyncTask. Http requests can't be done from main thread because of strict mode.Here check AsyncTask.
