[Bug] Android Crash when open browser with Browser.OpenAsync()

[TranTrieuLamQuynh]

Description

Steps to Reproduce

I have a problem when open custom tab with Browser.OpenAsync(). But it is very difficult to reproduce. But happens a lot with users. We can only investigate through the AppCenter log.
Has anyone had the same problem as me? Or does anyone have a workaround for this?
Thanks for the help.

Expected Behavior

Browser.OpenAsync() not crash

Actual Behavior

Browser.OpenAsync() crash in CustomTabsIntent.LaunchUrl()

Basic Information

• Version with issue: 1.7.3
• Last known good version: no version
• IDE: VS for Mac/Rider
• Platform Target Frameworks:
• Android: API 32

random thought:
when using Launcher.OpenAsync(uri) it is recommended to wrap it around with a check for Launcher.CanOpenAsync(uri). perhaps you need a similar check? maybe the uri you are trying to access directly in Browser.OpenAsync(uri) isn't recognised by some of your user's devices and it is blowing up?

I found that some uris would make android devices crash but they'd work fine on iOS and Windows, so there is a degree of variance that you should consider when dealing with this sort of issue.

as a follow-up to my previous comment, I've found that sometimes Lancher.CanOpenAsync would return false even though the launcher.OpenAsync worked just fine, so I ended up replacing CanOpenAsync with a try/catch. This fault became apparent when the device had more than one application that could open the uri and CanOpenAsync no longer worked as expected.
