Use FLAG_SECURE for Android.

Hi All,

I know expo does not support this at the moment.
I want to create a security screen when the user switch out of the app.
I can use AppState to pop up a modal screen when the user switch out of the app on IOS.
But it does not work on Android.

So I found a solution to add 4 lines of native Android code to the MainActivity file. like this


For reference please check out this blog post.

So I wonder is there anyway to accomplish this? Even means that I need to create a native module for Expo something like expo-secure-store. I don’t really know the process, if someone can point me to the right path, it’d be greatly appreciated.
