Android Webview just showing as black in Single App Kiosk Model

expand collapsive



I’m trying to find the setting in hexnode that is making any webview i show in my app to appear as black/blank.

It is also happening when i use youtube.  It is a flutter app running on android, it works fine outside hexnode so i think its some missing app from my background apps.


Any help would be greatly appreciated.

    If your app is opening a webview it is better you add that specific website as a “webapp” in itself, and add it into Kiosk mode’s background apps.

    This is a case of your application (store/ in-house) opening a webview. It shall open well if you have an in-built webview like Facebook. If not, you can add that specific URL as a webapp into background apps.

    But if you are still facing trouble you can ping them directly, those chaps, real fast..

    Hi Neil & Valerie,

    Thank you for questions and solutions.

    As mentioned by Valerie, it would be best to add the webview as a backgrounded webapp in kiosk mode.

    You need to navigate to Apps -> Add Apps -> Webapp. Here, you can enter the website that needs to open in kiosk -> Create the webapp.

    Then, you can add this webapp to the background apps of your kiosk policy.

    Else, if you need to add a browser to open up webviews, you can do that as well, by installing a browser and adding it to your list of background apps. But please note that when this is done, the user might be able to browse any website.
