How to save application state and get data on restart?

Question

React Native

There is an application for android on react native.
Uses react-native-image-picker ( link ) to access the camera.
The user takes his photo (avatar) and sends it to the server.

There was a problem on some phones - the phone apparently kills the application after opening the camera. And after taking a photo, he opens it again.
The problem is described here .

The topic above suggests saving the state of the application and opening it on the desired screen after the snapshot.
Tell me - how to save the state (probably in storage?) And how to get data from the camera with such a return to the application?
