How to load an image from Web on Android

Find below complete code for a simple application that loads an image from web. You have to insert the url and click the button. You can use this example in your applications when you need to load images from web.

Add this line in your AndroidManifest.xml file:

Layout main.xml


package com.blog.loadimage;

import java.io.IOException;
import java.io.InputStream;
import java.net.MalformedURLException;
import java.net.URL;

import android.app.Activity;
import android.content.Context;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.text.Editable;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;

public class main extends Activity {
 EditText imageUrl;
    /** Called when the activity is first created. */
    public void onCreate(Bundle savedInstanceState) {
        imageUrl = (EditText)findViewById(R.id.editTextUrl);
  Button getImageButton = (Button)findViewById(R.id.buttonGetImage);
  getImageButton.setOnClickListener( new View.OnClickListener() {   
   public void onClick(View v) {    
     Context context = v.getContext();
     Editable ed = imageUrl.getText();
     Drawable image = ImageOperations(context,ed.toString(),"image.jpg");
     ImageView imgView = new ImageView(context);
     imgView = (ImageView)findViewById(R.id.imageView);
    private Drawable ImageOperations(Context ctx, String url, String saveFilename) {
  try {
   URL imageUrl = new URL(url);
   InputStream is = (InputStream) imageUrl.getContent();
   Drawable d = Drawable.createFromStream(is, "src");
   return d;
  } catch (MalformedURLException e) {
   return null;
  } catch (IOException e) {
   return null;

I've come across this many times now while looking for a solution to this, but I'm curious—what is the significance of the Context and saveFile parameters in the ImageOperations method? I don't see a time when they are referenced within the method, or any time where a Context is even necessary.

Those getting errors, check the formatting of the main.xml, capitalisation of the tags is incorrect .. fixed it for me.
ie change to EditText, Image, ButtonView

Probably goes without saying, remove the comment tags from the XML declaration in the first line too ;)
