How can I display a list of installed applications in React Native and show their respective icons along with their names?
How to display a list of installed applications in React Native, including:
Retrieving the list of installed applications
Displaying the names and icons of the applications
Implementing the display using the best practices and efficient methodologies in React Native.
I would probably use this library: https://www.npmjs.com/package/react-native-installed-application
Initialize the library, get list of apps and persist it in some form of state.
Create a component with a list that uses the previous saved state to render the elements.
I tried searching for it and only found something like react organizational chart, react-d3-tree, BALKAN
OrgChartJS,
react-orgchart. All of that seems to works with ReactJS (for website) but not React Native. Is there any React Native Library to create organization hierarchy or tree diagram?
I want to use Kendo UI React with my React Native application but I got some problems with the getting started.
I followed every step inside https://www.telerik.com/kendo-react-ui/getting-started/ but I encounter this error : "Invariant Violation: View config not found for name button"
So is there a way to use it in my react native mobile application ?
Kendo React can´t be implemented in React native at the moment. Telerik is considering since August last year to implement it according to market demand.

You should consider a different UI library or stack for your project.
Nativescript can be a valid option depending on your needs.

I'm trying to understand how I can do a signature capture in React Native. My App is created with create-react-native-app and Expo and I'd prefer to not have to eject the app to get this functionality to work.
Would it be possible to wrap something like this in a webview? https://github.com/szimek/signature_pad
I've also looked at this project, https://github.com/RepairShopr/react-native-signature-capture but it requires me to eject the app and use react-native link.
Looking for any advice or suggestions on how to implement this feature while keeping my project as straightforward as possible (ideally, using create-react-native-app, but if this isn't possible could someone please explain to me why?)
The way React Native works is that each component available in React Native maps to a native component in the underlying platform.
ie. a <Image /> is an ImageView in Android and a UIImageView.h in iOS.
The Javascript code itself runs in a Javascript thread on each platform and as you use Components in React Native, there's a translation layer that passes information from JS into the React Native bridge that then results in corresponding native components being created.
By default, React Native has included the following components: https://facebook.github.io/react-native/docs/components-and-apis.html#basic-components which means that only those components come out-of-the-box in React Native. If you want other components, then you have 2 options, either create a "composite" component in which your JS component is written into other JS components or, if your feature needs a native component not yet exposed by React Native, write your own "native" component to expose certain native functionality to your React Native code.
The way Expo works is that they have wrapped React Native and a handful of 3rd party components and built it within their application. The reason why you can't use a 3rd party native component they don't support is because when that component is used, the app itself doesn't have translation code to go from JS to a native Android/iOS view.
So, to do what you're asking, you'd need to find either a "native" drawing component that Expo has included in their platform/app. OR you need to find a "composite" drawing component that is built with other default React Native components (or other components Expo supports).
ie. On Android, I might build this with a Canvas view, but from what I can tell React Native doesn't support that object natively, so I would probably write this myself, etc.
It's hard for Expo to support every 3rd party "native" component out there because React Native is open source and it iterates so fast that most community-built components aren't always up to date or they might conflict with one another.
I am using react-native-signature-capture.
Working properly on both Android and iOS.
I know it's been a while, but there is an interesting article here: https://blog.expo.io/drawing-signatures-with-expo-25d1629ca1ac
Wait, but how?
Using “expo-pixi”, you can add a component that lets you choose your brush’s color, thickness, and opacity. Then when your user lifts her finger, you get a callback. From there you can take a screenshot of the transparent view or get the raw point data if that’s what you’re looking for.
I was looking for an android Business Card Scanner project that I can integrate with my React Native App.Is there anything like that out there ?
I have written one like that which has all the logic to scan(OCR) and map the respective fields e.g Fname,Lname,designation,phone numbers etc but that was for native iOS and Android .
Checkout this link
This runs on the engine I created, I used tesseract for OCR , react native wrapper for that is available here
