Check the official Android docs : http://developer.android.com/reference/android/view/KeyCharacterMap.html#deviceHasKey%28int%29

The method deviceHasKey will solve your problem. (Use Keycodes KEYCODE_MENU, KEYCODE_HOME, KEYCODE_BACK). Hope it helps.

Maybe by doing the following check in your onCreate():

for api 14 and up

boolean PermanentMenuKey = ViewConfiguration.get(this).hasPermanentMenuKey(); // true if physical, false if virtual

for lower api:

boolean hasBackKey = KeyCharacterMap.deviceHasKey(KeyEvent.KEYCODE_BACK);
boolean hasHomeKey = KeyCharacterMap.deviceHasKey(KeyEvent.KEYCODE_HOME);

if (hasBackKey && hasHomeKey) {
    // no navigation bar, unless it is enabled in the settings
} else {
    // 99% sure there's a navigation bar
}

found solution here, but not 100% guarantee to work for all device, some device like HTC, LAVA etc not working with that. Also minApi required 13+ for that...!!
