Android system browser

Starting with MSAL.NET 2.4.0-preview (not yet released), MSAL.NET supports browsers other than Chrome and no longer requires Chrome be installed on the Android device for authentication.

It is recommended to use browsers which support custom tabs, such as the following browsers:

Browsers with custom tabs support	Package Name
Chrome	com.android.chrome
Microsoft Edge	com.microsoft.emmx
Firefox	org.mozilla.firefox
Ecosia	com.ecosia.android
Kiwi	com.kiwibrowser.browser
Brave	com.brave.browser

In addition to browsers with custom tab support, based on our testing, a few browsers that do not support custom tabs will also work for authentication, such as Opera, Opera Mini, InBrowser, and Maxthon. See table for test results.

Known Issues

• If the user has no browser enabled on the device, MSAL.NET will throw an ActivityNotFoundException with a link to this page. You will want to suggest the user enable a browser (preferably one with custom tab support) on their device.

• If authentication fails (ex. authentication launches with DuckDuckGo and we know this will fail), MSAL.NET will return an AuthenticationCanceled MsalClientException, with a link to this page. You will want to suggest the user install a browser (preferably one with custom tab support) on their device.
