How to detect soft menu key available in android device? -


i check menu key presence in device in android application. achieve used following code detect weather device having hardware menu or not , working fine

!viewconfiguration.get(scscommander.getinstance().getapplicationcontext()).haspermanentmenukey()

but did not find logic find weather device having soft menu present or not.

please suggest me there way detect soft menu available or not in device.

there no reliable/clean way check if soft menu (aka navigation bar) present or not!

you may try using below code (not tested on devices , not reliable solution anyways):

boolean hasnavbar(context context) {     resources resources = context.getresources();     int id = resources.getidentifier("config_shownavigationbar", "bool", "android");     if (id > 0) {         return resources.getboolean(id);     } else {    // check keys         boolean hasmenukey = viewconfiguration.get(context).haspermanentmenukey();         boolean hasbackkey = keycharactermap.devicehaskey(keyevent.keycode_back);         return !hasmenukey && !hasbackkey;     } }

here, fetching resource identifier using resources class. looking resource "navigation bar" passed 1st parameter.

the getidentifier returns associated resource identifier. returns 0 if no such resource found. (0 not valid resource id.)

in case if approach fails, in else trying see check if physical keys present on device back or home constitute navigation bar.
