In the MainActivity/OnCreate method, I would like to pass the URI of the incoming Intent to the instance of the MainPage class. How can I do that?

Hello, You need to override the MAUI App Lifecycle method to do it. Please refer to App lifecycle to get details and sample. Update: I've reproduced your issue. It is caused by something error in MAUI 6.0.4 and above, if I switched the MAUI version to 6.0.312, the project would run as expected. Therefore, it is recommended to post your issue in MAUI issues .

Hi Alec,
Thank you for your answer.
According to the document you provided I implemented a handler for the android event "OnCreate".
It sort of works, but after the handler is called I get an exception in the android MainActivity/OnCreate method. (please see the attachment)
Any idea what is wrong?
Thank you
Vaclav Jedlicka

For further investigation, could you please provide more detailed information about how did you set the handler for it?

the app is here:
https://github.com/proficad/Viewer_Maui

the crash line is marked as "it crashes here"

steps to reproduce:

run the app in debugger

switch to google drive, double tap an a file with extension "sxe"

select "Viewer_Maui"

the app crashes by the comment "it crashes here"

Thanks
Vaclav

Can you please advice how to change the maui version?
I am trying to do it in the "Manage Nuget packages" and getting error
"Cannot modify an evaluated object originating in an imported file "C:\Program Files\dotnet\packs\Microsoft.Maui.Sdk\6.0.486\Sdk\BundledVersions.targets".

Thanks
Vaclav

You could add <MauiVersion>6.0.312</MauiVersion> into your project file to change the MAUI version.
