how to blur app screenshot in the task switcher (aka alt-tab) for security?

[axelnormand]

Much like many banking apps, I’d like to blur my apps screenshot in the task switcher.
Is there a hook in expo to do this using say BlurView maybe?

iOS notes on using applicationDidEnterBackground to do this: https://developer.apple.com/library/archive/qa/qa1838/_index.html

Many thanks

applicationDidEnterBackground

Hi @axelnormand-- You might be able to hook into applicationDidEnterBackground and similar lifecycle things using AppState. https://facebook.github.io/react-native/docs/appstate.html

Brilliant! Guess i’ll just render something like a logo or blurview in the render method of the <App>.

Ill try and report back,
Thanks
