Project Description

  • In this tutorial, we will see how to load an image from URL into Android ImageView.
  • For downloading the image from URL and loading it in ImageView, we use AsyncTask.

Environment Used


Android Project

Create an Android project and name it as “ImageViewFromURL“.


Open res/values/strings.xml and replace it with following content.

<?xml version="1.0" encoding="utf-8"?>
    <string name="hello">ImageView from URL</string>
    <string name="app_name">ImageViewFromURL</string>

XML layout file

This application uses XML layout file (main.xml) to display the ImageView.

Open main.xml file in res/layout and copy the following content.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=""
    android:orientation="vertical" >

        android:maxWidth="70dp" />



In src folder, create a new Class and name it as “ImageViewFromURLActivity” in the package “” and copy the following code.

From Android 3.x Honeycomb or later, you cannot perform Network IO on the UI thread and doing this throws android.os.NetworkOnMainThreadException. You must use Asynctask instead as shown below.



import android.os.AsyncTask;
import android.os.Bundle;
import android.widget.ImageView;

public class ImageViewFromURLActivity extends Activity {

	public static final String URL = 
	ImageView imageView;

	/** Called when the activity is first created. */
	public void onCreate(Bundle savedInstanceState) {
		imageView = (ImageView) findViewById(;

		// Create an object for subclass of AsyncTask
		GetXMLTask task = new GetXMLTask();
		// Execute the task
		task.execute(new String[] { URL });

	private class GetXMLTask extends AsyncTask<String, Void, Bitmap> {
		protected Bitmap doInBackground(String... urls) {
			Bitmap map = null;
			for (String url : urls) {
				map = downloadImage(url);
			return map;

		// Sets the Bitmap returned by doInBackground
		protected void onPostExecute(Bitmap result) {

		// Creates Bitmap from InputStream and returns it
		private Bitmap downloadImage(String url) {
			Bitmap bitmap = null;
			InputStream stream = null;
			BitmapFactory.Options bmOptions = new BitmapFactory.Options();
			bmOptions.inSampleSize = 1;

			try {
				stream = getHttpConnection(url);
				bitmap = BitmapFactory.
						decodeStream(stream, null, bmOptions);
			} catch (IOException e1) {
			return bitmap;

		// Makes HttpURLConnection and returns InputStream
		private InputStream getHttpConnection(String urlString)
				throws IOException {
			InputStream stream = null;
			URL url = new URL(urlString);
			URLConnection connection = url.openConnection();

			try {
				HttpURLConnection httpConnection = (HttpURLConnection) connection;

				if (httpConnection.getResponseCode() == HttpURLConnection.HTTP_OK) {
					stream = httpConnection.getInputStream();
			} catch (Exception ex) {
			return stream;
  • Whenever we need to perform lengthy operation or any background operation we can use Asyntask which executes a task in background and publish results on the UI thread without having to manipulate threads and/or handlers.
  • In onCreate(), we create and execute the task to load image from url. The task’s execute method invokes doInBackground() where we open a Http URL connection and create a Bitmap from InputStream and return it.
  • Once the background computation finishes, onPostExecute() is invoked on the UI thread which sets the Bitmap on ImageView.

Android includes two HTTP clients: HttpURLConnection and Apache HTTP Client.
For Gingerbread and later, HttpURLConnection is the best choice.


Define the activity in AndroidManifest.xml file. To access internet from Android application set the android.permission.INTERNET permission in manifest file as shown below.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android=""
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="15" />
    <!-- Allows applications to open network sockets. -->
    <uses-permission android:name="android.permission.INTERNET" />

        android:label="@string/app_name" >
            android:label="@string/app_name" >
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
