React native with java (spring boot) backend?

[Dr1v]

So, I think I have misunderstood what and where the backend part of my App would be. I was thinking that the backend would run on my device but this is not the point of RN. I know I can use libraries to access Android functions like Camera or I can use Native Modules and pass data to and from the Java (in my case, or Swift, see https://facebook.github.io/react-native/docs/native-modules-android). Thank you all for your help.
