Since I did not get any answers from the previous post, I am posting again.
I have many experiences in Android native development but am a beginner in React Native. Wish to build a React Native app but need to find out these answers before I can start making architecture:
Is it possible to import a native Android module/ SDK (which is programmed in Java/ Kotlin) into React Native app? (I believe it is yes as I saw many good articles on the internet)
If I import the native Android module/ SDK to React Native app, does the app runs on iOS devices as well? Able to use APIs which native Android module/ SDK supports? (Or do I need a native iOS module/ SDK for iOS itself?)
I think this is similar to question #2. After importing the native Android module, does it also run on the web without a problem?
Looking forward to getting answers.
Many thanks,
Yes it is possible to integrate Android Native Modules.
No app doesn't run on iOS device if you have only Android SDK, You need to have a native iOS module to integrate iOS Native Modules.
For Web, I don't think so since both are native modules.

I was wondering if FlutterFire's Firestore uses the same cache as the Android and iOS native Firestore libraries.
Current setup:
We have the app written for Android and iOS separately using the native Android/iOS client library for the platform.
Future setup:
We still have most parts of the app written in Android and iOS using the native libraries, but some parts may be written in Flutter to start sharing more and more code.
We would like to use FlutterFire in the Flutter parts.
Now I'm wondering if the Firestore Flutter SDK will share the cache with the native SDKs, so we don't accidentally cache the same things twice on one device, just because of the dual setup of Flutter with existing native code.
The Flutter SDK for Firestore is just a wrapper around the native SDKs for Android and iOS, so I'm fairly certain that direct access from the native SDK is effectively the same as access via Flutter, and they will use the same local cache.
I try to build Shopify end point shop application in Xmaramin.
Shopify provides native buy-sdk for Android and IOS which handle communication with API, therefore I was thinking about writing some in-app API based on interface that is implemented in projects for particular OS calling native library and communicate with Xamarin app.
I found some native libraries/wrappers for Shopify that covers API in version 2 which was realized in RESTful technology. Unfortunately version 3 API is realized using GraphQL. I cant't find any Xamarin lib which using Shopify API version 3.
I try to create BindingsLibrary project based on buy-sdk AAR file but output library don't contains all classes few examples below:
I try write Android project that hides calls to sdk but it don't work either.
Is there any solution to use Shopify buy-sdk in Xamarin project?
The recently launched react native features just iOS app example and docs.
Yes.
React Native for Android was released September 14th, 2015.
Docs: http://facebook.github.io/react-native/
No. You can't build Android apps with this release.
Facebook has indicated that they are working on an Android version, and famously said "give us 6 months", which some people have taken as a promise. I wouldn't base any important business decisions on the illusion that it will be unveiled when the 6 months is over, but you can at least take some hope in the fact that they're serious about making it production-ready before they give us access to it, and that it's not just a pie-in-the-sky hope.
Also, as others have pointed out, Facebook has already release apps that they've built with the Android version of React Native. So at least parts of it are ready for prime time.
UPDATE
Early support for React Native for Android has been pushed to GitHub!
As noted, there are several things that are currently not working if trying to port an application from iOS. But it's worth checking out.
https://github.com/facebook/react-native/commit/42eb5464fd8a65ed84b799de5d4dc225349449be
It is not aiming to be a cross platform, write-once run-anywhere, tool. It is aiming to be learn-once write-anywhere. -Colin Eberhardt, from Raywenderlich
Good news is that React Native for Android is finally here. (https://code.facebook.com/posts/1189117404435352)
while you can't do it right now, it shouldn't take that long.
The first React Native Android App has been published about two weeks ago in the play store as tweeted by the reactjs twitter account:
https://twitter.com/reactjs/status/615638361328349185
Great news! Now its possible!

I've tried out Facebook react native on Android and it really worked.
Simple Ubuntu install guide can be found here
Simple js files: link
Yes , We can now developed android apps too in react-native.
and some of the apps are already developed in react-native for android
suchs as:
1)F8
2)Facebook ads manager
3)Squad
4)Discovery VR
5)Ziliun etc..
and many more still counting.
Developers from around the world now opting react-native for mobile app development because of easy of use of JSX syntax.
and also it is commonly noted as simply the V in MVC.
Since React makes no assumptions about the rest of your technology stack, it's easily embeddable within an existing non-React Native app.
TLDR; Yes,
Detailed answer (As of November 2017)
React Native android application development is very stable and a good number of Android applications have been already built and used in production using React-Native.
You can find a showcase of applications here. Most of them have both IOS and Android versions.
You can also easily integrate your native Android java code to react-native. Refer here
As a developer who is building Android app using react-native with a lot of native java code dependencies, react-native runs stable and I found the documentation and community support is adequate.
Yes, it works for both the platforms ios and android, be sure to mention code entry points in app.js if it uses different code for different platforms. However native functions like native events or location manager need to be coded in native languages and then exported using RCT_EXPORT, you can find more about it in the docs
Sure,
Using React Native you can build real mobile app. real app means close to platform or simply can say 99% native app.react native provide easy way for building native android app using javascript for lucrative design.You have basic knowledge of android studio and error fixing in android studio related native module integration and good understanding of react.js then you can build android app using react native.
Basic Requirement for android app
1. Configure android studio please follow below link and avoid installation of python.
https://facebook.github.io/react-native/docs/getting-started .
2. for UI you will learn flex-box from official documentation.
I thing that is enough
Yes, not just with android but also with iOS using XCode
Yes, you can make real-world mob application with React-Native. React-Native is used to create a hybrid mobile application. In this, we write code in javascript which gets converted to swift for ios and java for android.
Yes, You can build the Android app using React Native. For this, you have to install Android Studio with all the required SDKs. You can run your React Native app in Android simulator by using Android Studio and command line both.
For command line, run the following command:
react-native run-android
Otherwise you can open the android project in Android Studio which is created by React Native in android folder and run the project from there.
Happy Coding.. :)
Yes, you can definitely build android apps using react-native.This is one of the great benefits of React Native. Before Facebook created it, you had to build your app twice and with different code : one for iOS using Swift or Objective-C and one for Android using Java or Kotlin.
When porting my Android app to Blackberry 10/Playbook, I get the error:
native-code: x86
This error has also been reported here and here. The app uses OpenCV for Android as a library project, which contains native code, and I'm aware that Blackberry lists native code as an unsupported feature. Is there any way to get apps with native code to work on Blackberry, even for experimental purposes?
From what I can tell, you'll have to port it over to Blackberry's Native Platform.
http://developer.blackberry.com/develop/platform_choice/ndk.html
It looks like Blackberry put up a rough port on Github.

I haven't used it so I can't comment on how well it works.
