boolean hasPermanentMenuKey ()

Report if the device has a permanent menu key available to the user.

However, there are some apps where the action bar is inappropriate or undesirable. This method may be used to detect if a menu key is present. If not, applications should provide another on-screen affordance to access functionality.

Returns
`boolean`	true if a permanent menu key is present, false otherwise.
