Can I get info about device in react native? - react-native

How I should get the info about device in react native:
— What applications I have used and how many hours?
— The percentage of battery?

Related to your question, yes, you can get info about your device in React Native.
For a basic usage you should check libraries already built like react-native-device-info
And to access information from "outside" the scope of your app, you'll need to implemente your own solution. React Native - Native Modules
Hope this helps! :)

I am using bugsnag in react native to track bugs and I want fallback to custom component when error occurs. For React fall back component mentioned in docs. But in react native I didn't find. How to use this. Help me out
You're best contacting Bugsnag support directly to get a quick response to queries about the product.
Bugsnag doesn't yet support error boundaries in React Native like we do for React but we plan to in the near future. We're also about to start officially supporting Expo as a platform and will be supporting error boundaries on that.

react-native-navigation with context api (react 16.3)

has anybody being able to use the new Context API introduce in react 16.3 with react-native-navigation?
I'm having trouble trying to set it up as with react-native-navigation there is no main component where i can manage a state and then render the Context.Provider components, just the Navigation.startSingleScreenApp or similar functions.
Tks in advance for any help you can provide
Environment
React Native Navigation version: 1.1.403
React Native version: 0.55.4
Platform(s): iOS
Device info : Simulator
Please update your question with the simplest code example that shows your problem.
Generally, you can wrap your for example outside or inside whatever is your .
Maybe see this guide https://medium.com/#505aaron/a-practical-react-native-problem-solved-with-the-context-api-eecaf2e05202 for a simple enough example that does create a custom Context Provider/Consumer pair that also has its own state.
react-native-navigation with Context API is not possible. there are some workarounds (https://github.com/wix/react-native-navigation/issues/3549#issuecomment-411800487) but it is not the real React Context API behavior.

what is showsUserHeadingIndicator in react native mapbox?

How are you.
I am going to show direction of user's heading in mapbox,
In IOS version, showsUserHeadingIndicator variable exist for it,
but in React Native, there is no such variable.
so what is the alternative of this one?
Thank you.q
showsUserHeadingIndicator is available in react-native map-box. You can enable the showsUserHeadingIndicator on the user location in MGLMapView. The indicator is so small to notice.
