Check if Android device has software or hardware navigation buttons

Question

I\'m writing an Android app with a transparent navigation bar. To adjust the layout accordingly, I need to know whether the device has software or hardware buttons.

The answer posted here did the trick. Just for completeness, here is the code I am using now:

private static boolean hasImmersive;
private static boolean cached = false;

@SuppressLint ("NewApi")
public static boolean hasImmersive(Context ctx) {

    if (!cached) {
        if(Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
            hasImmersive = false;
            cached = true;
            return false;
        }
        Display d = ((WindowManager) ctx.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();

        DisplayMetrics realDisplayMetrics = new DisplayMetrics();
        d.getRealMetrics(realDisplayMetrics);

        int realHeight = realDisplayMetrics.heightPixels;
        int realWidth = realDisplayMetrics.widthPixels;

        DisplayMetrics displayMetrics = new DisplayMetrics();
        d.getMetrics(displayMetrics);

        int displayHeight = displayMetrics.heightPixels;
        int displayWidth = displayMetrics.widthPixels;

        hasImmersive = (realWidth > displayWidth) || (realHeight > displayHeight);
        cached = true;
    }

    return hasImmersive;
}
