Authorization code not received when authenticating in Android WebView

I’d like to report that it’s impossible to authorize third party app using Android WebView. All Android apps seem to be affected by that unless they use external browser or Box app for auth.

 

Regular flow should be: Login page → enter credentials → Grant access page

Current broken flow is: Login page → enter credentials → Blank page and no authorization code returned

 

I was able to capture error log from js console, I guess this prevents the grant page from showing

    It is tripping on that exception because by default the WebView has local storage (aka DOM storage) disabled and the JS code is expecting it to be enabled.

     

    You can trivially fix it enabling local storage on the WebView:

     

    WebView webView = ...
    webView.getSettings().setDomStorageEnabled(true);
