Load image from url in notification Android

Question

In my android application, i want to set Notification icons dynamically which will be loaded from URL. For that, i have used setLargeIcon property of NotificationBuilder in receiver.I reffered many link and tried various solutions but couldn't get desired output. Though i downloaded that image from url and setting that bitmap in notification, it is not being displayed. Instead it displays the setSmallIcon image as large icon. I don't know where i am going wrong. Here i am posting my code. Please help me to solve this issue. Thank you.

Code:

@SuppressLint("NewApi") public class C2DMMessageReceiver extends BroadcastReceiver {      @Override     public void onReceive(Context context, Intent intent) {         String action = intent.getAction();         if ("com.google.android.c2dm.intent.RECEIVE".equals(action)) {             Log.e("C2DM", "received message");             final String fullName = intent.getStringExtra("message");             final String payload1 = intent.getStringExtra("message1");             final String payload2 = intent.getStringExtra("message2");             final String userImage = intent.getStringExtra("userImage");              Log.e("userImage Url :", userImage); //it shows correct url              new sendNotification(context)                     .execute(fullName, payload1, userImage);         }     }  private class sendNotification extends AsyncTask<String, Void, Bitmap> {          Context ctx;         String message;          public sendNotification(Context context) {             super();             this.ctx = context;         }          @Override         protected Bitmap doInBackground(String... params) {              InputStream in;             message = params[0] + params[1];             try {                  in = new URL(params[2]).openStream();                 Bitmap bmp = BitmapFactory.decodeStream(in);                 return bmp;              } catch (MalformedURLException e) {                 e.printStackTrace();             } catch (IOException e) {                 e.printStackTrace();             }             return null;         }          @Override         protected void onPostExecute(Bitmap result) {              super.onPostExecute(result);             try {                 NotificationManager notificationManager = (NotificationManager) ctx                         .getSystemService(Context.NOTIFICATION_SERVICE);                  Intent intent = new Intent(ctx, NotificationsActivity.class);                 intent.putExtra("isFromBadge", false);                   Notification notification = new Notification.Builder(ctx)                         .setContentTitle(                                 ctx.getResources().getString(R.string.app_name))                         .setContentText(message)                         .setSmallIcon(R.drawable.ic_launcher)                         .setLargeIcon(result).build();                  // hide the notification after its selected                 notification.flags |= Notification.FLAG_AUTO_CANCEL;                  notificationManager.notify(1, notification);              } catch (Exception e) {                 e.printStackTrace();             }         }     }

Changed my code as below and its working now :

private class sendNotification extends AsyncTask<String, Void, Bitmap> {          Context ctx;         String message;          public sendNotification(Context context) {             super();             this.ctx = context;         }          @Override         protected Bitmap doInBackground(String... params) {              InputStream in;             message = params[0] + params[1];             try {                    URL url = new URL(params[2]);                   HttpURLConnection connection = (HttpURLConnection)url.openConnection();                   connection.setDoInput(true);                   connection.connect();                   in = connection.getInputStream();                   Bitmap myBitmap = BitmapFactory.decodeStream(in);                   return myBitmap;             } catch (MalformedURLException e) {                 e.printStackTrace();             } catch (IOException e) {                 e.printStackTrace();             }             return null;         }          @Override         protected void onPostExecute(Bitmap result) {              super.onPostExecute(result);             try {                 NotificationManager notificationManager = (NotificationManager) ctx                         .getSystemService(Context.NOTIFICATION_SERVICE);                  Intent intent = new Intent(ctx, NotificationsActivity.class);                 intent.putExtra("isFromBadge", false);                   Notification notification = new Notification.Builder(ctx)                         .setContentTitle(                                 ctx.getResources().getString(R.string.app_name))                         .setContentText(message)                         .setSmallIcon(R.drawable.ic_launcher)                         .setLargeIcon(result).build();                  // hide the notification after its selected                 notification.flags |= Notification.FLAG_AUTO_CANCEL;                  notificationManager.notify(1, notification);              } catch (Exception e) {                 e.printStackTrace();             }         }     }
