try
{
    // Open app with Google Play app
    intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id="+sParam));
    startActivity(intent);
}
catch (android.content.ActivityNotFoundException anfe)
{
    // Open Google Play website
    intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id="+sParam));
    startActivity(intent);
}
