Android - How can I display an image from a URL?

Android - How can I display an image from a URL? - android

I have an ImageView and all I need to do is display an image from the intetrnet when the app loads. Is there a very simple way to do this?

ImageView.setImageURI does not seem to work for internet resources, so you should read the bitmap yourself.
InputStream is = new URL("http://example.com/myimage.jpg").openStream();
Bitmap bitmap = BitmapFactory.decodeStream(is);
is.close();
ImageView iv = (ImageView) findViewById(R.id.myImage);
iv.setImageBitmap(bitmap);
But this loads the image on the UI thread, which can cause hiccups. It is preferable to do it in a different thread, for example using:
new AsyncTask<String, Void, Bitmap>() {
protected Bitmap doInBackground(String... params) {
try {
return loadBitmap(params[0]);
} catch (Exception e) {
Log.e("imagetask", "error loading bitmap", e);
return null;
}
}
protected Bitmap loadBitmap(String urlSpec) throws IOException {
InputStream is = new URL(urlSpec).openStream();
try {
return BitmapFactory.decodeStream(is);
} finally {
is.close();
}
}
protected void onPostExecute(Bitmap bitmap) {
if (bitmap != null) {
ImageView iv = (ImageView) findViewById(R.id.myImage);
iv.setImageBitmap(bitmap);
}
}
}.execute("http://example.com/myimage.jpg");

HttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet( url);
HttpResponse response = client.execute( get );
Bitmap bitmap = BitmapFactory.decodeStream( response.getEntity().getContent() );

Android- inserting external image from URL to placeholder in the app

Pretty new to Android development, haven't found the answer needed.
I have an ImageView some layout.xml:
<ImageView
android:layout_width="48dp"
android:layout_height="48dp"
android:src="#drawable/placeholder"
android:layout_alignParentRight="true" />
Instead the placeholder, I want to load some specific image from url that i have.
How can it be achieved?

for download the image for url ,first download that image and saved it in Bitmap
public static Bitmap loadBitmap(String url) {
Bitmap bitmap = null;
InputStream in = null;
BufferedOutputStream out = null;
try {
in = new BufferedInputStream(new URL(url).openStream(),IO_BUFFER_SIZE);
final ByteArrayOutputStream dataStream = new ByteArrayOutputStream();
out = new BufferedOutputStream(dataStream, IO_BUFFER_SIZE);
copy(in, out);
out.flush();
final byte[] data = dataStream.toByteArray();
BitmapFactory.Options options = new BitmapFactory.Options();
//options.inSampleSize = 1;
bitmap = BitmapFactory.decodeByteArray(data, 0, data.length,options);
} catch (IOException e) {
Log.e(TAG, "Could not load Bitmap from: " + url);
} finally {
closeStream(in);
closeStream(out);
}
return bitmap;
Than you can set image by call that method
image.setImageBitmap(bitmap);
Hope it will help you

Use Picasso Library for android to download images from url and display onto ImageView
Its very easy to use like this
Picasso.with(context).load("http://your_image_url").into(your_imageView);

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 from your onCreate() method using:
new DownloadImageTask((ImageView) findViewById(R.id.imageView1))
.execute(MY_URL_STRING);
Dont forget to add below permission in your manifest file
<uses-permission android:name="android.permission.INTERNET"/>

you may try ImageLoader,you can download it here https://github.com/nostra13/Android-Universal-Image-Loader

Why can't I retrieve FaceBook profile pic in Android?

I am trying to retrieve my FaceBook Profile pic using a Url in Android. I am not able to retrieve any image. I have no error logs as such but I get the following Log.
04-05 04:14:41.005: D/skia(2987): --- SkImageDecoder::Factory returned null. I am posting the codes. Please tell me step by step what am I doing wrong.
final ImageView photoImageView=(ImageView)findViewById(R.id.imageView1);
AsyncTask<Void, Void, Bitmap> t = new AsyncTask<Void, Void, Bitmap>(){
protected Bitmap doInBackground(Void... p) {
Bitmap bm = null;
try {
URL aURL = new URL("http://graph.facebook.com/+"id"+/picture?type=small");
URLConnection conn = aURL.openConnection();
conn.setUseCaches(true);
conn.connect();
InputStream is = conn.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
bm = BitmapFactory.decodeStream(bis);
bis.close();
is.close();
// photoImageView.setImageBitmap(bm);
} catch (IOException e) {
e.printStackTrace();
}
return bm;
}
protected void onPostExecute(Bitmap bm){
// Drawable drawable = new BitmapDrawable(getResources(), bm);
photoImageView.setImageBitmap(bm);
// photoImageView.setBackgroundDrawable(drawable);
}
};
t.execute();

Try this below code, This is perfectly working for me.
try {
URL image_value = new URL("http://graph.facebook.com/"+ user.getId()+ "/picture?type=large");
Bitmap bmp = null;
try {
bmp = BitmapFactory.decodeStream(image_value.openConnection().getInputStream());
} catch (IOException e) {
e.printStackTrace();
}
profile_pic.setImageBitmap(bmp);
} catch (MalformedURLException e) {
e.printStackTrace();
}

URL aURL = new URL("https://graph.facebook.com/"+id+"/picture?type=small");
Try this.
And if id is integer convert to string
And also not http , try https

JSON to retrieve image

I am using JSON to retrieve user data and I am also getting the image URL but how can I show the image instead of the URL? Currently it only shows the URL from the image.
Here is the code:
StringBuilder tweetResultBuilder = new StringBuilder();
try {
//get JSONObject from result
JSONObject resultObject = new JSONObject(result);
//get JSONArray contained within the JSONObject retrieved - "results"
JSONArray tweetArray = resultObject.getJSONArray("results");
//loop through each item in the tweet array
for (int t=0; t<tweetArray.length(); t++) {
//each item is a JSONObject
JSONObject tweetObject = tweetArray.getJSONObject(t);
//get the username and text content for each tweet
tweetResultBuilder.append(tweetObject.getString("from_user")+": ");
tweetResultBuilder.append(tweetObject.get("profile_image_url")+"\n");
tweetResultBuilder.append(tweetObject.get("text")+"\n\n");
}
}

You should download and cashe you image first.
Please read this article Displaying Bitmaps Efficiently, and check Sample application
The shorter way to display image from url:
new DownloadImageTask((ImageView) findViewById(R.id.imageView1))
.execute("http://java.sogeti.nl/JavaBlog/wp-content/uploads/2009/04/android_icon_256.png");
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);
}
}

You need to download image from the url you are getting.
For that you need to do following things.
ImageView my_image = (ImageView) findViewById(R.id.my_imageView);
String image_url = "http://www.clker.com/cliparts/1/d/7/e/12570918991185627521Ramiras_Earth_small_icon.svg.med.png";
Bitmap bm = getImageFromServer(image_url);
my_image.setImageBitmap(bm);
This will call the following function to download image.
private Bitmap getImageFromServer(String image_url) {
Bitmap bm = null;
try {
URL aURL = new URL(image_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("DEBUGTAG", "Remtoe Image Exception", e);
}
return bm;
}
That's it. Hope this helps you somehow.
Thanks.

try this one
try {
ImageView i = (ImageView)findViewById(R.id.image);
Bitmap bitmap = BitmapFactory.decodeStream((InputStream)new URL(imageUrl).getContent());
i.setImageBitmap(bitmap);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

How can I fetch a large image from a url?

I used the code below to fetch the image from a url but it doesn't working for large images.
Am I missing something when fetching that type of image?
imgView = (ImageView)findViewById(R.id.ImageView01);
imgView.setImageBitmap(loadBitmap("http://www.360technosoft.com/mx4.jpg"));
//imgView.setImageBitmap(loadBitmap("http://sugardaddydiaries.com/wp-content/uploads/2010/12/how_do_i_get_sugar_daddy.jpg"));
//setImageDrawable("http://sugardaddydiaries.com/wp-content/uploads/2010/12/holding-money-copy.jpg");
//Drawable drawable = LoadImageFromWebOperations("http://www.androidpeople.com/wp-content/uploads/2010/03/android.png");
//imgView.setImageDrawable(drawable);
/* try {
ImageView i = (ImageView)findViewById(R.id.ImageView01);
Bitmap bitmap = BitmapFactory.decodeStream((InputStream)new URL("http://sugardaddydiaries.com/wp-content/uploads/2010/12/holding-money-copy.jpg").getContent());
i.setImageBitmap(bitmap);
} catch (MalformedURLException e) {
System.out.println("hello");
} catch (IOException e) {
System.out.println("hello");
}*/
}
protected Drawable ImageOperations(Context context, String string,
String string2) {
// TODO Auto-generated method stub
try {
InputStream is = (InputStream) this.fetch(string);
Drawable d = Drawable.createFromStream(is, "src");
return d;
} catch (MalformedURLException e) {
e.printStackTrace();
return null;
} catch (IOException e) {
e.printStackTrace();
return null;
}
}

You're trying to download the Large Image from within the UI Thread....This will cause an ANR (Application not Responding)
Use AsyncTask to download the images, that way, a seperate thread will be used for the download and your UI Thread wont lock up.

see this good example that loads image from server.
blog.sptechnolab.com/2011/03/04/android/android-load-image-from-url/.

If you want to download the image very quickly then you can use AQuery which is similar to JQuery just download the android-query.0.15.7.jar
Import the jar file and add the following snippet
AQuery aq = new AQuery(this);
aq.id(R.id.image).image("http://4.bp.blogspot.com/_Q95xppgGoeo/TJzGNaeO8zI/AAAAAAAAADE/kez1bBRmQTk/s1600/Sri-Ram.jpg");
// Here R.id.image is id of your ImageView
// This method will not give any exception
// Dont forgot to add Internet Permission

public class MyImageActivity extends Activity
{
private String image_URL= "http://home.austarnet.com.au/~caroline/Slideshows/Butterfly_Bitmap_Download/slbutfly.bmp";
private ProgressDialog pd;
private Bitmap bitmap;
private ImageView bmImage;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
bmImage = (ImageView)findViewById(R.id.imageview);
pd = ProgressDialog.show(this, "Please Wait", "Downloading Image");
DownloadWebPageTask task = new DownloadWebPageTask();
task.execute(new String[] { image_URL });
// You can also give more images in string array
}
private class DownloadWebPageTask extends AsyncTask<String, Void, Bitmap>
{
// String --> parameter in execute
// Bitmap --> return type of doInBackground and parameter of onPostExecute
#Override
protected Bitmap doInBackground(String...urls) {
String response = "";
for (String url : urls)
{
InputStream i = null;
BufferedInputStream bis = null;
ByteArrayOutputStream out =null;
// Only for Drawable Image
// try
// {
// URL url = new URL(image_URL);
// InputStream is = url.openStream();
// Drawable d = Drawable.createFromStream(is, "kk.jpg");
// bmImage.setImageDrawable(d);
// }
// catch (Exception e) {
// // TODO: handle exception
// }
// THE ABOVE CODE IN COMMENTS WILL NOT WORK FOR BITMAP IMAGE
try
{
URL m = new URL(image_URL);
i = (InputStream) m.getContent();
bis = new BufferedInputStream(i, 1024*8);
out = new ByteArrayOutputStream();
int len=0;
byte[] buffer = new byte[4096];
while((len = bis.read(buffer)) != -1)
{
out.write(buffer, 0, len);
}
out.close();
bis.close();
byte[] data = out.toByteArray();
bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);
}
catch (Exception e)
{
e.printStackTrace();
}
}
return bitmap;
}
#Override
protected void onPostExecute(Bitmap result)
{
if(result!=null)
bmImage.setImageBitmap(result);
pd.dismiss();
}
}
}

How to load an ImageView by URL in Android?

How do you use an image referenced by URL in an ImageView?

From Android developer:
// show The Image in a ImageView
new DownloadImageTask((ImageView) findViewById(R.id.imageView1))
.execute("http://java.sogeti.nl/JavaBlog/wp-content/uploads/2009/04/android_icon_256.png");
public void onClick(View v) {
startActivity(new Intent(this, IndexActivity.class));
finish();
}
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);
}
}
Make sure you have the following permissions set in your AndroidManifest.xml to access the internet.
<uses-permission android:name="android.permission.INTERNET" />

1. Picasso allows for hassle-free image loading in your application—often in one line of code!
Use Gradle:
implementation 'com.squareup.picasso:picasso:(insert latest version)'
Just one line of code!
Picasso.get().load("http://i.imgur.com/DvpvklR.png").into(imageView);
2. Glide An image loading and caching library for Android focused on smooth scrolling
Use Gradle:
repositories {
mavenCentral()
google()
}
dependencies {
implementation 'com.github.bumptech.glide:glide:4.11.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.11.0'
}
// For a simple view:
Glide.with(this).load("http://i.imgur.com/DvpvklR.png").into(imageView);
3. fresco is a powerful system for displaying images on Android applications. Fresco takes care of image loading and display, so you don't have to.
Getting Started with Fresco

You'll have to download the image firstly
public static Bitmap loadBitmap(String url) {
Bitmap bitmap = null;
InputStream in = null;
BufferedOutputStream out = null;
try {
in = new BufferedInputStream(new URL(url).openStream(), IO_BUFFER_SIZE);
final ByteArrayOutputStream dataStream = new ByteArrayOutputStream();
out = new BufferedOutputStream(dataStream, IO_BUFFER_SIZE);
copy(in, out);
out.flush();
final byte[] data = dataStream.toByteArray();
BitmapFactory.Options options = new BitmapFactory.Options();
//options.inSampleSize = 1;
bitmap = BitmapFactory.decodeByteArray(data, 0, data.length,options);
} catch (IOException e) {
Log.e(TAG, "Could not load Bitmap from: " + url);
} finally {
closeStream(in);
closeStream(out);
}
return bitmap;
}
Then use the Imageview.setImageBitmap to set bitmap into the ImageView

Anyway people ask my comment to post it as answer. i am posting.
URL newurl = new URL(photo_url_str);
mIcon_val = BitmapFactory.decodeStream(newurl.openConnection().getInputStream());
profile_photo.setImageBitmap(mIcon_val);

I wrote a class to handle this, as it seems to be a recurring need in my various projects:
https://github.com/koush/UrlImageViewHelper
UrlImageViewHelper will fill an
ImageView with an image that is found
at a URL.
The sample will do a Google Image
Search and load/show the results
asynchronously.
UrlImageViewHelper will automatically
download, save, and cache all the
image urls the BitmapDrawables.
Duplicate urls will not be loaded into
memory twice. Bitmap memory is managed
by using a weak reference hash table,
so as soon as the image is no longer
used by you, it will be garbage
collected automatically.

The accepted answer above is great if you are loading the image based on a button click, however if you are doing it in a new activity it freezes up the UI for a second or two. Looking around I found that a simple asynctask eliminated this problem.
To use an asynctask add this class at the end of your activity:
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 from your onCreate() method using:
new DownloadImageTask((ImageView) findViewById(R.id.imageView1))
.execute(MY_URL_STRING);
The result is a quickly loaded activity and an imageview that shows up a split second later depending on the user's network speed.

You could also use this LoadingImageView view to load an image from a url:
http://blog.blundellapps.com/imageview-with-loading-spinner/
Once you have added the class file from that link you can instantiate a url image view:
in xml:
<com.blundell.tut.LoaderImageView
android:id="#+id/loaderImageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
image="http://developer.android.com/images/dialog_buttons.png"
/>
In code:
final LoaderImageView image = new LoaderImageView(this, "http://developer.android.com/images/dialog_buttons.png");
And update it using:
image.setImageDrawable("http://java.sogeti.nl/JavaBlog/wp-content/uploads/2009/04/android_icon_256.png");

The best modern library for such a task in my opinion is Picasso by Square. It allows to load an image to an ImageView by URL with one-liner:
Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").into(imageView);

public class LoadWebImg extends Activity {
String image_URL=
"http://java.sogeti.nl/JavaBlog/wp-content/uploads/2009/04/android_icon_256.png";
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageView bmImage = (ImageView)findViewById(R.id.image);
BitmapFactory.Options bmOptions;
bmOptions = new BitmapFactory.Options();
bmOptions.inSampleSize = 1;
Bitmap bm = LoadImage(image_URL, bmOptions);
bmImage.setImageBitmap(bm);
}
private Bitmap LoadImage(String URL, BitmapFactory.Options options)
{
Bitmap bitmap = null;
InputStream in = null;
try {
in = OpenHttpConnection(URL);
bitmap = BitmapFactory.decodeStream(in, null, options);
in.close();
} catch (IOException e1) {
}
return bitmap;
}
private InputStream OpenHttpConnection(String strURL) throws IOException{
InputStream inputStream = null;
URL url = new URL(strURL);
URLConnection conn = url.openConnection();
try{
HttpURLConnection httpConn = (HttpURLConnection)conn;
httpConn.setRequestMethod("GET");
httpConn.connect();
if (httpConn.getResponseCode() == HttpURLConnection.HTTP_OK) {
inputStream = httpConn.getInputStream();
}
}
catch (Exception ex)
{
}
return inputStream;
}
}

Hi I have the most easiest code try this
public class ImageFromUrlExample extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageView imgView =(ImageView)findViewById(R.id.ImageView01);
Drawable drawable = LoadImageFromWebOperations("http://www.androidpeople.com/wp-content/uploads/2010/03/android.png");
imgView.setImageDrawable(drawable);
}
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;
}
}
}
main.xml
<LinearLayout
android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<ImageView
android:id="#+id/ImageView01"
android:layout_height="wrap_content"
android:layout_width="wrap_content"/>
try this

I have recently found a thread here, as I have to do a similar thing for a listview with images, but the principle is simple, as you can read in the first sample class shown there (by jleedev).
You get the Input stream of the image (from web)
private InputStream fetch(String urlString) throws MalformedURLException, IOException {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet request = new HttpGet(urlString);
HttpResponse response = httpClient.execute(request);
return response.getEntity().getContent();
}
Then you store the image as Drawable and you can pass it to the ImageView (via setImageDrawable). Again from the upper code snippet take a look at the entire thread.
InputStream is = fetch(urlString);
Drawable drawable = Drawable.createFromStream(is, "src");

Lots of good info in here...I recently found a class called SmartImageView that seems to be working really well so far. Very easy to incorporate and use.
http://loopj.com/android-smart-image-view/
https://github.com/loopj/android-smart-image-view
UPDATE: I ended up writing a blog post about this, so check it out for help on using SmartImageView.
2ND UPDATE: I now always use Picasso for this (see above) and highly recommend it. :)

This is a late reply, as suggested above AsyncTask will will and after googling a bit i found one more way for this problem.
Drawable drawable = Drawable.createFromStream((InputStream) new URL("url").getContent(), "src");
imageView.setImageDrawable(drawable);
Here is the complete function:
public void loadMapPreview () {
//start a background thread for networking
new Thread(new Runnable() {
public void run(){
try {
//download the drawable
final Drawable drawable = Drawable.createFromStream((InputStream) new URL("url").getContent(), "src");
//edit the view in the UI thread
imageView.post(new Runnable() {
public void run() {
imageView.setImageDrawable(drawable);
}
});
} catch (IOException e) {
e.printStackTrace();
}
}
}).start();
}
Don't forget to add the following permissions in your AndroidManifest.xml to access the internet.
<uses-permission android:name="android.permission.INTERNET" />
I tried this myself and i have not face any issue yet.

imageView.setImageBitmap(BitmapFactory.decodeStream(imageUrl.openStream()));//try/catch IOException and MalformedURLException outside

This will help you...
Define imageview and load image into it .....
Imageview i = (ImageView) vv.findViewById(R.id.img_country);
i.setImageBitmap(DownloadFullFromUrl(url));
Then Define this method :
public Bitmap DownloadFullFromUrl(String imageFullURL) {
Bitmap bm = null;
try {
URL url = new URL(imageFullURL);
URLConnection ucon = url.openConnection();
InputStream is = ucon.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
ByteArrayBuffer baf = new ByteArrayBuffer(50);
int current = 0;
while ((current = bis.read()) != -1) {
baf.append((byte) current);
}
bm = BitmapFactory.decodeByteArray(baf.toByteArray(), 0,
baf.toByteArray().length);
} catch (IOException e) {
Log.d("ImageManager", "Error: " + e);
}
return bm;
}

String img_url= //url of the image
URL url=new URL(img_url);
Bitmap bmp;
bmp=BitmapFactory.decodeStream(url.openConnection().getInputStream());
ImageView iv=(ImageView)findviewById(R.id.imageview);
iv.setImageBitmap(bmp);

Version with exception handling and async task:
AsyncTask<URL, Void, Boolean> asyncTask = new AsyncTask<URL, Void, Boolean>() {
public Bitmap mIcon_val;
public IOException error;
#Override
protected Boolean doInBackground(URL... params) {
try {
mIcon_val = BitmapFactory.decodeStream(params[0].openConnection().getInputStream());
} catch (IOException e) {
this.error = e;
return false;
}
return true;
}
#Override
protected void onPostExecute(Boolean success) {
super.onPostExecute(success);
if (success) {
image.setImageBitmap(mIcon_val);
} else {
image.setImageBitmap(defaultImage);
}
}
};
try {
URL url = new URL(url);
asyncTask.execute(url);
} catch (MalformedURLException e) {
e.printStackTrace();
}

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;
}

A simple and clean way to do this is to use the open source library Prime.

This code is tested, it is completely working.
URL req = new URL(
"http://java.sogeti.nl/JavaBlog/wp-content/uploads/2009/04/android_icon_256.png"
);
Bitmap mIcon_val = BitmapFactory.decodeStream(req.openConnection()
.getInputStream());

Working for imageView in any container , like listview grid view , normal layout
private class LoadImagefromUrl extends AsyncTask< Object, Void, Bitmap > {
ImageView ivPreview = null;
#Override
protected Bitmap doInBackground( Object... params ) {
this.ivPreview = (ImageView) params[0];
String url = (String) params[1];
System.out.println(url);
return loadBitmap( url );
}
#Override
protected void onPostExecute( Bitmap result ) {
super.onPostExecute( result );
ivPreview.setImageBitmap( result );
}
}
public Bitmap loadBitmap( String url ) {
URL newurl = null;
Bitmap bitmap = null;
try {
newurl = new URL( url );
bitmap = BitmapFactory.decodeStream( newurl.openConnection( ).getInputStream( ) );
} catch ( MalformedURLException e ) {
e.printStackTrace( );
} catch ( IOException e ) {
e.printStackTrace( );
}
return bitmap;
}
/** Usage **/
new LoadImagefromUrl( ).execute( imageView, url );

Try this way,hope this will help you to solve your problem.
Here I explain about how to use "AndroidQuery" external library for load image from url/server in asyncTask manner with also cache loaded image to device file or cache area.
Download "AndroidQuery" library from here
Copy/Paste this jar to project lib folder and add this library to project build-path
Now I show demo to how to use it.

public class MainActivity extends Activity {
private AQuery aQuery;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
aQuery = new AQuery(this);
aQuery.id(R.id.imageFromUrl).progress(R.id.pbrLoadImage).image("http://itechthereforeiam.com/wp-content/uploads/2013/11/android-gone-packing.jpg",true,true);
}
}
Note : Here I just implemented common method to load image from url/server but you can use various types of method which can be provided by "AndroidQuery"to load your image easily.

Android Query can handle that for you and much more (like cache and loading progress).
Take a look at here.
I think is the best approach.

Android - How can I display an image from a URL? - android

I have an ImageView and all I need to do is display an image from the intetrnet when the app loads. Is there a very simple way to do this?

HttpClient client = new DefaultHttpClient(); HttpGet get = new HttpGet( url); HttpResponse response = client.execute( get ); Bitmap bitmap = BitmapFactory.decodeStream( response.getEntity().getContent() );
