No 'exitEvent' when app is killed on Android

Did you verify this is a real problem by searching [Stack Overflow]

Yes, I’ve also searched in the issues here and found the same issue reported: #438 But sadly that ticket is closed without a solution.

Which platform(s) does your issue occur on?

Android

Please provide the following version numbers that your issue occurs with:

• CLI: 3.1.3
• Cross-platform modules: 3.1.0
• Runtime(s): 3.1.1

Please tell us how to recreate the issue in as much detail as possible.

I’m starting my plain TypeScript (without Angular) app. When I exit (or kill) the app, the event does not get fired. The event doesn’t even get fired when I kill my app via button like the following: android.os.Process.killProcess(android.os.Process.myPid());

I need to mention that the suspendEvent is logged without any issues, as well as the launchEvent and the resumeEvent. Only exitEvent doesn’t get triggered.

Is there code involved? If so, please share the minimal amount of code needed to recreate the problem.

...
application.on(app.launchEvent, (args: app.ApplicationEventData) => {
	console.log('app.ts -> launchEvent');
});

application.on(application.resumeEvent, (args: application.ApplicationEventData) => {
	console.log("app.ts -> resumeEvent");
});

application.on(application.suspendEvent, (args: application.ApplicationEventData) => {
	console.log('app.ts -> suspendEvent');
});

application.on(application.exitEvent, (args: application.ApplicationEventData) => {
	console.log('app.ts -> exitEvent');
});

app.start({ moduleName: 'pages/main/main' });

Thanks for the explanation, @NickIliev!

Now I can understand why this app doesn’t throw this event. But I’m still facing some serious issues because of that. My app plays a some voice via TTS (https://github.com/bradmartin/nativescript-texttospeech) and I want the app to stop talking, as soon as the app gets closed. Currently the speech engine doesn’t stop talking, when I kill the app. That’s somewhat annoying. And I don’t want it to stop when I minimize it (suspendEvent). Any ideas or recommendations?

Thanks @NickIliev, but I’m aware of how the events usually work. As I stated earlier, the resumeEvent fires as expect, when I minimize the app.

What circumstances could cause my issue, that the exitEvent doesn’t get fired, even when I kill the process like I described in my initial post? I would expect the event to be fired, no matter if I kill the process via Android command (see above) or if I just close the window in the task manager, or select “kill all” in the task manager. I don’t receive the exitEvent. 😞
