Open a Directory of Downloads by Clicking the Notification
<p>Hello there I am newbie in Android Development. What I am trying to do is:</p>

<ol>
<li>Downloading a file using a URL</li>
<li>Placed it in my downloads</li>
<li>Used a Download Manager within IntentService for downloading</li>
<li>Upon completion of the downloading, I am showing a Notification</li>
<li>The notification notify's the user for the download completion</li>
</ol>

<hr>

<p>The problem is that I want the user to tap on the generated notification, and to open the <strong>Downloads Folder</strong>!</p>

<p>What I have been trying is:</p>

<pre><code>public void sendNotification() {

        // Use NotificationCompat.Builder to set up our notification.
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this);

        //icon appears in device notification bar and right hand corner of notification
        builder.setSmallIcon(R.drawable.downloaded);

        // This intent is fired when notification is clicked
        *****Here I want the user if clicks this notification the Download Folder should Open up*****
        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);

        Uri imgUri = Uri.fromFile(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS));

        intent.setDataAndType(imgUri, "file/*");
        startActivity(intent);

        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);

        // Set the intent that will fire when the user taps the notification.
        builder.setContentIntent(pendingIntent);

        // Large icon appears on the left of the notification
        builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.downloaded));

        // Content title, which appears in large type at the top of the notification
        builder.setContentTitle("Complete");

        // Content text, which appears in smaller text below the title
        builder.setContentText("Your Download has been completed Successfully!");

        //set the subtext
        builder.setSubText("Click to open the Downloads Folder!");
        NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

        // Will display the notification in the notification bar
        notificationManager.notify(NOTIFICATION_ID, builder.build());
    }
</code></pre>
