lets selected mode landscape-left , app goes in background , user rotated device if happens want record video in landscape-left only;

i have tried following 

public void onconfigurationchanged(configuration newconfig) {     int orientation = getresources().getconfiguration().orientation; }

but seems dosen't event on home screen. can resolve issue?

thanks in advance

you can use broadcastreceiver background service like:

private final broadcastreceiver mreceiver = new broadcastreceiver() {     @override     public void onreceive(context context, intent intent) {         if (intent != null) {             if (intent.action_configuration_changed.equals(intent.getaction())) {                 //configuration has changed             }         }     } };  @override public void oncreate() {     super.oncreate();     registerreceiver(mreceiver, new intentfilter(intent.action_configuration_changed)); }  @override public void ondestroy() {     super.ondestroy();     unregisterreceiver(mreceiver); }

you can find more information on in documention.

broadcast action: current device configuration (orientation, locale, etc) has changed. when such change happens, uis (view hierarchy) need rebuilt based on new information; part, applications don't need worry this, because system take care of stopping , restarting application make sure sees new changes. system code can not restarted need watch action , handle appropriately.

note intent can retrive registerreceiver, not manifest via intent filter
