説明

Description

In API Level 34 Google introduced https://developer.android.com/reference/android/location/Location#getMslAltitudeMeters(). If available it should be used as altitude source to get consistent results on all platforms.

Public API Changes

Should be either the new default for Android or an option in GeolocationRequest and GeolocationListeningRequest.

Intended Use-Case

This change would make getting GPS altitude consistent on all platforms without manually correcting it.

.NET MAUI Recommended implementation

Because this API isn't supported on Windows.

I would be curious if there's a way to expose the platform location type through the xplat type.

For example, on all of our DragAndDrop args we've added versions of "PlatformDragEventArgs" which expose the underlying platform events.

This way we don't have to go one by one for every API that's on some xplat implementations but not others

調査方針
Investigate the current implementation of geolocation in dotnet/maui's Essentials library, specifically the Android platform code. Look at the `Location` class in Android and how altitude is currently handled. Consider the suggestion in the issue to expose platform specific location types, similar to `PlatformDragEventArgs`. Also review the Android documentation for `getMslAltitudeMeters()` to understand its requirements and availability.
