I want to inject a key event into my Android emulator from command line. Does anybody know how to inject a window key event to an application from command line? Or more specifically, how can I inject a key event to Android emulator?
Thanks.

I have a ZEBRA device with Android 11. How do I use key event.
When a open logcat you can see in it OnKeyEvent and TriggerKeyEvent. Does anyone know how to handle this event on a call from the keyboard .?
I need my Xamarin.App to run in background and show up it's window whenever globally available is pressed.
How can that be done with Xamarin.Mac?
I'm building a little app which needs to recognize if certain keys on the keyboard were pressed. In this case the arrow keys. The app must take action when these keys get pressed, even if it's not the frontmost and has no focus.
Is this possible to do? What would I have to do to receive these keyboard events no matter where they happen?
You do this by registering a hotkey using Carbon's RegisterEventHotKey function. There are also open source libraries available that make this easier, for example SGHotKeysLib.
I am attempting to handle the loss of focus of my application, either by a phone call or other event, and also by the pressing of the home key.
I have tried setting a flag in the OnNavigatingFrom/OnNavigatedFrom and OnNavigatedTo event handlers but each time the app starts (either after pressing home, or something else) it always seems to be resetting the flag.
Which are the correct events I should be using in order to correctly "pause" and subsequently "resume" my application if it loses focus?
You should read the documentation about application lifecycle.
When you press the Home button, or when you receive a phone call, the application is paused.
If you pressed Home, you can then restore the application by pressing the back button.
to handle these events, in App.xaml.cs by default the methods are: Application_Activated and Application_Deactivated
Of course you can manage to store data before the pause, and restore it when application is restored.
This is called tombstoning.
What you need is described in the following links:

Read this. This is a microsoft tutorial on how to save state.
It'll give you how to save your ApplicationData when it is tombstoned.
Basically edit the Application_Closing and Application_Activated methods in the App.xaml to save the data to the system using isolated storage.
I'm trying to write an application that prevents certain key signals from propagating beyond the OS in OSX. To clarify, I want to make it so that it almost seems to the user that the key they are pushing on their keyboard is broken. So, the associated letter won't show up in a textarea, the key won't activate a function in another application, etc. Any ideas? Thanks in advance.
You probably want to look into Quartz Event Taps. Note that your process will need to be running with "root" privileges to intercept events at the system level.
