How to intercept the pressure of a physical key (volume /power on), especially during stand by
Member ✭✭
Hello,
I need to intercept the long press of a physical key (any) at any time.
Through the OnKeyUp and OnKeyDown methods it work properly, but it only works as long as the app is active.
If the device is put on standby or if the lock screen is active, it no longer works.
How can this result be achieved?
Thanks

To intercept key event at any time, try to use BroadcastReceiver to achieve this. A broadcast receiver allows an application to respond to messages (an Android Intent) that are broadcast by the Android operating system or by an application.
[BroadcastReceiver(Enabled = true, Exported = false)] public class SampleReceiver : BroadcastReceiver { public override void OnReceive(Context context, Intent intent) { // Do stuff here. } }Tutorial about Broadcast Receivers:

Good evening Jarvan,
I'm sorry but due to contingent problems we haven't yet been able to test the proposed solution for the moment.
It will be my duty to inform you asap, in the meantime if you need to mark the topic as closed I think it is right.
Thanks
