Detect soft navigation bar availability in android device progmatically?

Following method worked for me and tested in many devices.

public boolean hasNavBar (Resources resources)    {        int id = resources.getIdentifier("config_showNavigationBar", "bool", "android");        return id > 0 && resources.getBoolean(id);    }

Note: Verified this method in real device

As i know you can detect it by

boolean hasSoftKey = ViewConfiguration.get(context).hasPermanentMenuKey();

But it required APIs 14+

If above solution doesn't work for you then try below method

public boolean isNavigationBarAvailable(){        boolean hasBackKey = KeyCharacterMap.deviceHasKey(KeyEvent.KEYCODE_BACK);        boolean hasHomeKey = KeyCharacterMap.deviceHasKey(KeyEvent.KEYCODE_HOME);        return (!(hasBackKey && hasHomeKey));    }

Its a hack but it works fine. Try it.

public static boolean hasSoftKeys(WindowManager windowManager){  Display d = windowManager.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;  return (realWidth - displayWidth) > 0 || (realHeight - displayHeight) > 0;}
