java - How to detect screen orientation change? - JavaFX on Microsoft Surface -


i writing javafx application microsoft surface , looking way detect screen orientation change when rotating device portrait landscape , vice versa. current method using detect screen orientation follows: 

window.widthproperty().addlistener((obs, oldval, newval) -> {     if((double) newval < window.getheight()) {         setportraitmode();     } else {         setlandscapemode();     } });

this method works fine manual window resizing. however, orientation change (device rotation) not trigger window resize event, method change layout not fire automatically.

what proper way detect screen orientation change without listening resizing event?

the solution issue check change in aspect ratio. condition used: 

    if((double) newval < window.getheight() || ((double) newval/visualbounds.getheight() < 1.5)

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
