My Json array contains two images, How to download that through url/http and displays in activity

My json array contains two images, how to display that in activity? Those images are in the form of url. After and before are the imageviews, I want to know what is image download task and how can I use that.
after = (ImageView) findViewById(R.id.bfrdoogret);
before = (ImageView) findViewById(R.id.afterdogret);
}
class BackGround extends AsyncTask<String, String, String> {
#Override
protected void onPreExecute() {
super.onPreExecute();
dialog = ProgressDialog.show(Serialno.this, "",
"Searching. Please wait...", true);
dialog.setCancelable(true);
dialog.show();
}
#Override

String uri = "http://www.lorryguru.com/domains/dogs/retusingsno.php?district="+District+"&serialno="+SerialNo;
HttpGet httpGet = new HttpGet(uri);
HttpClient client = new DefaultHttpClient();
HttpResponse response;
StringBuilder stringBuilder = new StringBuilder();
try {
response = client.execute(httpGet);
HttpEntity entity = response.getEntity();
InputStream stream = entity.getContent();
int b;
while ((b = stream.read()) != -1)
{
stringBuilder.append((char) b);
}
}
catch (ClientProtocolException e)
{
e.printStackTrace();
}
catch (IOException e)
{
e.printStackTrace();
}
try
{
JSONArray arr = new JSONArray(stringBuilder.toString());
//result = jsonObj.getJSONArray(TAG_RESULT);
JSONObject c = arr.getJSONObject(0);
id = c.getString(TAG_ID);
district = c.getString(TAG_DISTRICT);
cit = c.getString(TAG_CITY);
serial_no = c.getString(TAG_SERIALNO);
gende = c.getString(TAG_GENDER);
wareno = c.getString(TAG_WARENO);
befor = c.getString(TAG_BEFORE);
afte = c.getString(TAG_AFTER);
latitude = c.getString(TAG_LATITUDE);
longitude = c.getString(TAG_LONGITUDE);
return "success";
}
catch (JSONException e)

Add this dependency in gradle compile 'com.squareup.picasso:picasso:2.5.2'
As per your getValues() method you will get url like this
String yourImageUrlHere= c.getString("whatever is your key");
Picasso.with(this)
.load(yourImageUrlHere)
.into(yourImageViewHere);

You have to add another async task after to your existing one, Code is following below.
class ImageDownloaderTask extends AsyncTask<String, Void, Bitmap>
{
private final WeakReference<ImageView> imageViewReference;
String murl;
ImageView showView;
public ImageDownloaderTask(ImageView imageView,String url) {
imageViewReference = new WeakReference<ImageView>(imageView);
murl=url;
showView=imageView;
}
#Override
protected Bitmap doInBackground(String... params) {
final Bitmap bitmap=downloadBitmap(murl);
if(murl!=null && bitmap!=null)
{
addBitmapToMemoryCache(murl, bitmap);
}
return bitmap;
}
#Override
protected void onProgressUpdate(Void... values) {
// TODO Auto-generated method stub
}
#Override
protected void onPostExecute(Bitmap bitmap) {
if (isCancelled()) {
bitmap = null;
}
if (imageViewReference != null) {
final ImageView imageView = imageViewReference.get();
if (imageView != null) {
if (bitmap != null) {
imageView.setImageBitmap(bitmap);
//addBitmapToMemoryCache(murl, bitmap);
}
}
}
}
}
private Bitmap downloadBitmap(String url)
{
HttpURLConnection urlConnection = null;
Bitmap bitmap;
try {
URL uri = new URL(url);
urlConnection = (HttpURLConnection) uri.openConnection();
int statusCode = urlConnection.getResponseCode();
if (statusCode != HttpStatus.SC_OK)
{
return null;
}
InputStream inputStream = urlConnection.getInputStream();
bitmap = BitmapFactory.decodeStream(inputStream);
return bitmap;
}
catch (Exception e)
{
urlConnection.disconnect();
Log.w("ImageDownloader", "Error downloading image from " + url);
}
finally
{
if (urlConnection != null) {
urlConnection.disconnect();
}
}
return null;
}

Use Picasso to download image asynchronously from url.

You can use Picasso:
Picasso.with(this)
.load(url)
.into(imageView);

Android: Downloading images crashing app on API 8

In my device ( API > 15 ) everything works great, but in API 10 it crashes the app... I you want , I can provide also OnClickListener or some othere methods...
Yes, here ... How I download pictures :
public Bitmap getBitmapFromURL(String src) {
try {
java.net.URL url = new java.net.URL(src);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
Bitmap myBitmap = BitmapFactory.decodeStream(input);
double width;
double height;
width = (screenWidth)/myBitmap.getRowBytes();
if ( myBitmap.getWidth() > myBitmap.getHeight() ){
Log.w("size","landscape");
height = ((myBitmap.getRowBytes()*width)/16)*11;
width = (height/11)*16;
}
else {
Log.w("size","protrait");
height = ((myBitmap.getRowBytes()*width)/11)*16;
width = (height/16)*11;
}
Bitmap bitmap = Bitmap.createScaledBitmap(myBitmap, (int)width, (int)height, true);
return bitmap;
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(Profile.this, "Error parsing image to bitmap", Toast.LENGTH_LONG).show();
return null;
}
}
Any help ?

call new loadPhotos().execute(""+USER._id,"date","DESC"); in onCreate and Use Asynctask and try to avoid load in main thread. Your application crash one of the main reason may be if you are calling the methode in main thread.
Ex:
String zoomouturl = "your url";
new ImageDownload().execute(zoomouturl);
Try
public class ImageDownload extends AsyncTask<String, Void, String> {
protected String doInBackground(String... params) {
// TODO Auto-generated method stub
bmOptions = new BitmapFactory.Options();
bmOptions.inSampleSize = 1;
loadBitmap(zoomouturl, bmOptions);
return zoomouturl;
}
protected void onPostExecute(String imageUrl) {
if (!imageUrl.equals("")) {
Constants._image.setImageBitmap(bm);
} else {
Toast.makeText(this,
"not found proper bitmap.. ", Toast.LENGTH_LONG)
.show();
}
}
}
and
public static Bitmap loadBitmap(String URL, BitmapFactory.Options options) {
InputStream in = null;
try {
in = OpenHttpConnection(URL);
bm = BitmapFactory.decodeStream(in, null, options);
in.close();
} catch (IOException e1) {
}
return bm;
}
private static 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;
}

Android image view from url
I am trying to fetch the image from url and load in imageView, but I cannot encode the url string, please let me know how to encode this.
Please find the code & url used for your reference.
URL: http://images.pcmac.org/SiSFiles/Schools/TN/JacksonMadisonCounty/RoseHillMiddle/Uploads/Locations/%7BB690E93E-F7C9-48AF-B72A-BFF944FA6D4A%7D_104_9169.JPG
Code
String link=URLEncoder.encode(urlStr);        
bitmap=loadBitmap(link);
public static Bitmap loadBitmap(String url) {
Bitmap bitmap = null;
try {
InputStream in = new java.net.URL(url).openStream();
bitmap = BitmapFactory.decodeStream(in);
} catch (Exception e) {
}
return bitmap;
}

Use this Code it will fetch the image from server
String URL = "http://images.pcmac.org/SiSFiles/Schools/TN/JacksonMadisonCounty/RoseHillMiddle/Uploads/Locations/%7BB690E93E-F7C9-48AF-B72A-BFF944FA6D4A%7D_104_9169.JPG";
private InputStream OpenHttpConnection(String urlString) throws IOException {

URLConnection conn = url.openConnection();
if (!(conn instanceof HttpURLConnection))
throw new IOException("Not an HTTP connection");
try {

httpConn.setAllowUserInteraction(false);
httpConn.setInstanceFollowRedirects(true);
httpConn.setRequestMethod("GET");
httpConn.connect();
response = httpConn.getResponseCode();
if (response == HttpURLConnection.HTTP_OK) {

}
} catch (Exception ex) {

}
});
}
return bitmap;
}

FYI, URLEncoder.encode(String) has been deprecated.
Reference:
http://developer.android.com/reference/java/net/URLEncoder.html

You can encode the url as below:
String URL = "http://images.pcmac.org/SiSFiles/Schools/TN/JacksonMadisonCounty/RoseHillMiddle/Uploads/Locations/%7BB690E93E-F7C9-48AF-B72A-BFF944FA6D4A%7D_104_9169.JPG";
String encodeUrl=URLEncoder.encode(URL, "utf-8");
private Bitmap DownloadImage(String URL) {
Bitmap bitmap = null;
InputStream in = null;
try {
in = OpenHttpConnection(URL);
bitmap = BitmapFactory.decodeStream(in);
in.close();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
final String msg = e1.getMessage();
handler.post(new Runnable() {
public void run() {
Toast.makeText(getApplicationContext(), "" + msg, Toast.LENGTH_SHORT).show();
}
});
}
return bitmap;
}
