long the time the zoom controls should be visible expressed in milliseconds.

hasPermanentMenuKey

Added in API level 14
boolean hasPermanentMenuKey ()

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

As of Android 3.0, devices may not have a permanent menu key available. Apps should use the action bar to present menu options to users. 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.
