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 can´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.

can you guys please guide me to make my react native app interacts with the phone VPN API so I can connect the configs file to it
I also want to build VPN with React NATIVE, but i Can't find proper library.
I Found this but i think old VERSION

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.
Often when viewing a website on a mobile device you'll get a notification that a mobile app is available, or if you already have the app downloaded you'll have the option to open the URL in the app.
Is there a native way to do this or are these notifications always custom?
When users click on a link or download a file and the suggestion pops up to open the respective app, that's called deep linking. iOS labels it as Universal Links and Android uses App Links.
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
I thinking about real technical advantages of creating React Native app over web SPA. I figured out that only 1 advantage could be - it's saving and loading data in phone store. Another things like, for example, access to GPS, camera, etc are also available in JavaScript Web. So, that is real technical advantage of using React Native over Web?
Overall, it really depends on what your application is for...
If your Application will be used by mobile users only, then React Native is a perfect solution. However, if you want an application with a Web presence, so users can use it on Desktops etc - then it wouldn't really be suitable unless you did both a Web SPA and a mobile app.
For example, if I were to create an accounting app - which will be used by users on Mobiles and Desktop, then perhaps I'd consider building a SPA which is mobile friendly or both SPA and an App with an API for both.
If you were building a tracking app, which will only be available for mobile - then go for it.
If your users will be using desktop, then you can build it perhaps in React and when you get to React Native you know the react library!
React Native in itself builds both iOS and Android Apps, so instead of creating a 'hybrid' app (which includes webviews) or a native App in both iOS and Android - you only create one code base and build it to your chosen OS. This saves alot of development time. As the community is open source, alot of upgrades happen and there is alot of help online if you encounter an issue.
