How to reuse the same react native instance across multiple actvities?

I have a brownfield Android application that has multiple activities, some of which are native and some of them react native.
What I wanted to know is that is there a way I can reuse the same react instance across all of my react native activities?
Right now, whenever we are creating a new activity that uses React Native, we have to initialize a new React Native instance and sync a lot of data along with rehydrating our entire redux store. This process is painfully slow and also consumes a lot of memory.

How to create a custom listview like this with react native?

I am new to React Native development. I tried to recreate the below listview with react native and It failed. I just want to know if we can recreate below UI design with react native or the name of this listview type.
Thank You.
Yes, you can recreate such component in react-native, however, it would be too complex to discuss it here. You can look into react-native-snap-carousel, which is the closest open-source library to your case that comes to mind.

React Native: Access Redux store from Native side (swift/objective C)

Part of our React Native App lets users use it in the background while they use other apps.
If the user then force quits the app while our app is in the background we want to do some cleanup and send some analytics. Since we can't get the applicationWillTerminate event in React Native we need to do this cleanup in the native side.
So we were wondering if there is a way to access the Redux store in this event. Or what is the suggested way to handle this?

React native for android

Can I use react native as a backend in Android
I want to use all the UI components from Android only but for the logic part I want to call react native and do the backend there
Is it possible ?
Let me summarize your question to see if I got it right: You would like to use Native UI Components in Android and compose/utilize them using React Native.
If so the answer is yes. React Native does nothing else under the hood, they try to map as directly as possible to the native UI concepts. If this is still too much JS UI layer for you, you can directly implement the Native UI Components you need and bridge them into React Native, as to be seen here.
As React native is doing for us to convert and other component in native android component. If you don't want to use this react native component code then you have to create native android module in react native to use native component. But it's not advisable.
