问题:

I want to open some links in external browser. Before opening I want to display the list of browsers in the device. I did this functionality using Intent.ACTION_VIEW. But as per my app's requirement, I want to display the list of browsers even if there is only one browser application in the device. Do any one have any idea about this. Thanks.

If you have one browser application , the chooser will not launched , the URL will be loaded on that browser application. If you have two or more browser applications, the android system launch an IntentChooser the show the list of all browser apps installed on the device , so the user can choose his preferred browser to load the URL :

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("http://www.stackoverflow.com"));
startActivity(intent);

EDIT : to create your custom Intent Chooser :

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("http://www.stackoverflow.com"));

// Always use string resources for UI text. This says something like "Share this photo with"
String title = getResources().getText(R.string.chooser_title);
// Create and start the chooser
Intent chooser = Intent.createChooser(intent, title);
startActivity(chooser);

Intent sendIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.maidofknowledge.com"));
            Intent chooser = Intent.createChooser(sendIntent, "Choose Your Browser");
            if (sendIntent.resolveActivity(getPackageManager()) != null) {
                startActivity(chooser);
            }
