Type of issue

Missing information

Description

A number of users have ran into issues with scenarios related to multi-window behavior and how android handles activities.

We're going to add some better logging into MAUI itself and modify the templates https://github.com/dotnet/maui/pull/21492

But, if users want multi window now on Android they'll need to understand the difference between various launchModes on android to fit their scenario.

LaunchModes are a pretty deep topic so we can just give a recommendation to delete the launchmode if they want multi window support but to read through https://developer.android.com/guide/topics/manifest/activity-element#lmode to fully understand how Android handles launchmodes.

It would also be useful to highlight that for single window scenarios users should wire into the OnNewIntent lifecycle if they want to process requests coming in to the existing activity.
