How can I get a large image from a url?

Question

I used the code below to extract an image from a URL, but it does not work for large images.

Am I missing something while getting this 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; } }

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

Answer 2

You are trying to load a large image from the UI thread .... This will call ANR (application not responding)

Use AsyncTask to download images. Thus, a separate thread will be used for loading, and your user interface will not be locked.

If you want to download the image very fast, you can use AQuery , which is similar to jQuery , just download 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(); } } }
