I am retrieving image from url and display them in imageview. but my code is giving me null message. 

ImageView imageview = (ImageView) findViewById(R.id.imageView1);
try {
    Uri uri=Uri.parse("http://10.0.2.2:8083/call/rahul.jpg");
    // uri.buildUpon().appendQueryParameter("key", "Android developer");
    URI u = new URI(uri.toString());
    System.out.println("path is "+u);
    HttpClient httpclient = new DefaultHttpClient();
    HttpGet httpget = new HttpGet();
    httpget.setURI(u);
    //httpget.setEntity(new UrlEncodedFormEntity(nameValuePairs));
    HttpResponse response = httpclient.execute(httpget);
    HttpEntity entity = response.getEntity();
    is = entity.getContent(); 

    Bitmap bitmap = BitmapFactory.decodeStream(is);
    imageview.setImageBitmap(bitmap); 
} catch(Exception e) {

    Well since you’ve said that what I suggested worked well for you, I guess I should submit it as an answer. I observed that you seem to be a long way off a working solution, and that since this problem has been solved many times before you might wish to use a library such as android-query. I have no affiliation with that library – I’ve just used it myself before. Also, since I didn’t technically answer your question, although I solved your problem, I’d better do a little more for the green tick, eh?

    Your usage of the library looks fine, and you don’t need to call recycle (you can find that on Google easily btw). Note that you can do lots of other nice stuff with it too, such as fading in the images when they load, downsampling them as they load if they are very large, and more. You can find lots of examples on the android-query site.

    As for your query about whether it is free, the license is declared on the main page I linked to, on the left hand side near the top. It’s the Apache License 2.0. In short this license allows you to use the library freely, as long as you include a copy of the Apache License in any distribution of your app and clearly mention any libraries you use under the license. Or you can read the blurb from their FAQ. You would typically put in an about screen in your app for this kind of thing, that clearly says you are using the android-query library under the Apache 2.0 license, with a viewable copy of the license. Proper attribution: I think you’ll agree it’s a small price to pay for so many useful things you can find under this license :o)

    Good luck with your app!
