LNA implications for Android Webview

[Michaelsulistio]

Question

Will the LNA restrictions affect native Android applications that use Android Webviews? e.g Capacitor apps, Webview shell apps

For example, if the URL loaded in the Webview attempts to connect to a localhost WebSocket connection, will it run into the LNA permission block?

• If no, is there any plan for this in the future?
• If yes, how can one test and verify this behavior?
• Are Chrome Custom Tabs also affected?

Hi @hubertchao , any idea on whether Android Webviews will be affected here?

[hubertchao]

Android WebView is explicitly out of scope for Chrome-based LNA restrictions. It is possible that this will change later on (or Android will develop its own LNA controls), but there is no current ETA for such a change.

Also: Chrome Custom Tabs should have LNA restrictions enabled.

To share some additional details -- https://developer.android.com/privacy-and-security/local-network-permission is planned for Android 16, and WebView will follow the permission of the hosting Android app (rather than rely on Web LNA enforcement).
