[severity:It bothers me. A fix would be nice] This is PRODUCTION issue. Line code: Browser.OpenAsync(url, BrowserLaunchMode.External); First happen after adding "await ", did not use it with async until now (don't now if related, just mentioning) Recently Xamarin.Essentials 1.70 Xamarin.Forms 5.0.0.2196

[Workaround]
Update:
Android 11 throws when using BrowserLaunchMode.External:
await Browser.OpenAsync(url, BrowserLaunchMode.External);
“Xamarin.Essentials.FeatureNotSupportedException: ‘Specified method is not supported.’”

When using BrowserLaunchMode.SystemPreferred it works sleek.

The issue is not related to the device, I have the same issue on Oppo phone with Android 11 and BrowserLaunchMode.External.

Also happening on Samsung Galaxy M11 Android 11

I have same problem on Nokia 5.3 Android 11 with BrowserLaunchMode.External when I changed it to BrowserLaunchMode.SystemPreferred it works.

Solution for this issue is here. If your project target Android version is set to Android 11 (R API 30) you must update your Android Manifest.

Add the following inside of the manifest node:

<queries>
  <intent>
    <action android:name="android.intent.action.VIEW" />
    <data android:scheme="http"/>
  </intent>
  <intent>
    <action android:name="android.intent.action.VIEW" />
    <data android:scheme="https"/>
  </intent>
</queries>

Add the following inside of the manifest node: <queries> <intent> <action android:name="android.intent.action.VIEW" /> <data android:scheme="http"/> </intent> <intent> <action android:name="android.intent.action.VIEW" /> <data android:scheme="https"/> </intent> </queries>

I have includes these queries, and even with this specified, i got this error on several Galaxy devices, LG K9, Xperia L3 running on Android 10 and 11

What is the url scheme? http/https? or is it a custom uri?

[softlion]

BrowserLaunchMode.External does not work on android device with android 11+ It crashes with FeatureNotSupportedException Tested on multiple devices.

[softlion]

Is that more related to the new "query" attribute required for app targeting api 30 ?

Duplicate of #1958 ?

    <data android:scheme="https"/>

</queries>

After adding this code and then doing a Clean & Compile on all projects works perfect!
