[Bug] NameNotFoundException: com.android.chrome

[Skirtek]

Which Version of MSAL are you using ?
MSAL v4.0.0

Platform
Xamarin Forms 4.1

What authentication flow has the issue?

• Desktop / Mobile
  • Interactive
  • Integrated Windows Auth
  • Username Password
  • Device code flow (browserless)
• Web App
  • Authorization code
  • OBO
• Web API
  • OBO

Is this a new or existing app?
The app is in production, and I have not upgraded to a new version of MSAL

Repro

1. Uninstall Chrome from rooted device
2. Try to log in/register in mobile app which is using MSAL library

Expected behavior
Method IsChromeEnabled should not throw exception and return false which should force open system browser.

Actual behavior
When user hasn't Chrome on his phone PackageManager throws NameNotFoundException: com.android.chrome. I can't uninstall Chrome on any device, so I'm a little bit scared that this user can not log in into application.

Possible Solution
Method IsChromeEnabled in AndroidPlatformProxy should catch exception and return false

Are you sure it's the Username / Password flow that you're using here? I'm pretty sure we don't call IsChromeEnabled except on Interactive flow. Username / Password is when your app collects the credentails on its own and passes them to MSAL (we discourage this for security reasons).
