How to detect if Google Play is installed? (Not Market)

Whether the app installed is called Google Play or Market, the package name is the same com.android.vending.

I need to be able to detect whether the app is Google Play or Market, I've checked in PackageInfo and nothing except versionCode and versionName can be of help.

Does anyone know what the first versionCode was or versionName was for Google Play app?

If anyone knows any other way of detecting this let me know.

I figured out how to check the application label. I was using the debugger to see what all was being returned in packageInfo that's why I didn't see it initially.

public static boolean isGooglePlayInstalled(Context context) {
    PackageManager pm = context.getPackageManager();
    boolean app_installed = false;
    try
    {
           PackageInfo info = pm.getPackageInfo("com.android.vending", PackageManager.GET_ACTIVITIES);
           String label = (String) info.applicationInfo.loadLabel(pm);
           app_installed = (label != null && !label.equals("Market"));
    }
    catch (PackageManager.NameNotFoundException e)
    {
           app_installed = false;
    }
    return app_installed;
}
