Android Monitor Home button

The game needs to count the user to exit the game is to press the return key or home, because the return key is their own cocos2dx to do the monitoring, so here say the Android activity listening Home key method, pro-test is available, here to do a backup which is also reference to other people's Code implementation, Path does not remember, if there is similar, hope forgive me ...

Here is a way to listen to the home operation in the form of a broadcast:

First, add the following broadcast in Mainactivity to generate a member variable:

 private final broadcastreceiver homereceiver = new broadcastreceiver ()  {      final String SYS_KEY =  "Reason";  // Label it must be such a string value       final String SYS_HOME_KEY =  "HomeKey" ;//Label It must be such a string value          @Override        public void onreceive (context context, intent intent)  {         string action = intent.getaction ();        if  (Action.equals (intent.action_close_system_dialogs)) {             string reason = intent.getstringextra (SYS_KEY);             if  (reason != null &&  reason.equals (Sys_home_kEY)) {             log.i ("TT",  "######### ######## #home键监听 ");                          }          }      } };

Then add the following method to the OnCreate method:

Intentfilter homefilter = new Intentfilter (intent.action_close_system_dialogs); Registerreceiver (Homereceiver, Homefilter);

Note When the app exits, remember to unregister the broadcast in the activity's OnDestroy method:

@Override protected void OnDestroy () {Super.ondestroy ();           if (homereceiver! = null) {try{unregisterreceiver (homereceiver);           }catch (Exception e) {log.e ("TT", "Unregisterreceiver homereceiver failure:" +e.getcause ()); }        }    }
