Hello,

In MAUI, you could use ConfigureLifecycleEvents to call the lifecycle event on each platform.

Please refer to Platform lifecycle events.

If you want to call the cross-platform lifecycle events, MAUI also provide the APIs to do it.

Please refer to Cross-platform lifecycle events.

Best Regards,

Alec Liu.

but this is for Android, so that means there is no more one onStartup for all platforms?

There are many cross-platform lifecycle events in MAUI.

Hi, The Platform lifecycle events - These events can be only overridden within the .MAUI App.xaml.cs module? Or can we get these events also at COntentPage level? THanks, Paul.

Hi,

Another question, I just tested running my .NET 8 MAUI app on my Mac mini IOS Simulator in debug mode and when I satrted the app, it hit the set breakpoint on this method within my App.xaml.cs file (it hits the breakpoint for both IOS and Android):

protected override void OnStart() { base.OnStart(); //await _settingsService.UpdateAllowGpsLocation(); }

But the documentation online reads this:
https://learn.microsoft.com/en-us/dotnet/maui/fundamentals/app-lifecycle?view=net-maui-8.0 Platform lifecycle events -> Android The following table lists the .NET MAUI delegates that are invoked in response to Android lifecycle events being raised: (Isn't this supposed to just hit the OnStart override for ANdroid only? What's up with this? " |OnStart|Android.App.Activity|Invoked after OnCreate or OnRestart when the activity has been stopped, but is now being displayed to the user.| | -------- | -------- | -------- | |OnStart|Android.App.Activity|Invoked after OnCreate or OnRestart when the activity has been stopped, but is now being displayed to the user.|
