How to know which app is getting used in background in your react native app? - react-native

I wanted to build an app which can send notifications to the user if he uses a particular app for more than 15 minutes...for this I need to trace which app the user is using even when my react native app is not being used(i.e. it is present in the background). Is there any react native library which can help me to know the app which the user is using in the present?

There's no way to do this. Your app would have to be running in the background at all times, and even then the OS would have to support such a feature.

Can we develop a web and mobile application (Android, iOS, web) with single code base by using React Native?

Can you please help with this.
I am trying to develop mobile and web apps using react native with single code base for web, android and ios. Can we Develop Web and Mobile Application with single code base by using React Native?
The simple answer is yes. However, there are a lot of caveats that you could encounter along the road with certain device requirements and functionality where you may have to write conditional code, but it could still stay in the same codebase.
The easiest way to get started is by using Expo (https://expo.io), which would let you get started with a project that could be run on Android, iOS, and the Web (via React Native Web) all with very minimal setup on your part.

React Native Mobile App also working on Web and Desktop

Does React Native support Web and Desktop targets?
I would like to build the main version of app as mobile.
Would it be possible to compile the same mobile app, maybe with minor modifications for Web and Desktop?
The user experience for the secondary use cases - Web and Desktop doesn't matter much, I need just the app more or less in a working state and it will be enough. Does React Native allows that?
For Web, you can use react-native-web

Detect when other Application is launched in React Native app

I want my react native app to detect when Google Maps app is open to show some travel tip. Is it possible?
You can not detect if another app is launched for security reasons. Installed apps canĀ“t listen another apps because they are "sandboxed".
You can only interact with another apps opening it throught your app by Deeplinking or detecting if is or not installed.
It's not a limitation of React Native. All iOS applications cannot access other applications, except to open it or share some resources.
