Hello,
so that once the Android OS boots it will directly open my application
For this need, you could use a broadcast receiver to implement app autostart. Please refer to Statically registering a Broadcast Receiver with an Intent Filter, although this document is under Xamarin.Android, but the implementation still works with MAUI.
and the user will have no access to anything else not even the taskbar & navigation buttons.
You can't completely block user navigation events, which is a limitation made by Google at the system level.
In Android, you could hide Android's system bar by fullscreen to achieve a similar effect.
Please refer to the following thread and Android documentation.
Best Regards,
Alec Liu.
