to display a list of installed apps, you can try this

final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
final List pkgAppsList = context.getPackageManager().queryIntentActivities( mainIntent, 0);

You will get all the necessary data in the ResolveInfo to start a application. You can check ResolveInfo

or try this code

PackageManager pm = this.getPackageManager();

    Intent intent = new Intent(Intent.ACTION_MAIN, null);
    intent.addCategory(Intent.CATEGORY_LAUNCHER);

    ArrayList<ResolveInfo> list = (ArrayList<ResolveInfo>) 
        pm.queryIntentActivities(intent, PackageManager.PERMISSION_GRANTED);
        for (ResolveInfo rInfo : list) {
        System.out.println("Installed Applications " + rInfo.activityInfo.applicationInfo.loadLabel(pm).toString());
        }
