npm install react-native

ns platform add android

In my-app/platforms/android/build.gradle add following from a react native project:

// ...
allprojects {
    repositories {
        google()
        jcenter()
        mavenLocal()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android")
        }
        maven {
            // Android JSC is installed from npm
            url("$rootDir/../node_modules/jsc-android/dist")
        }
    }
    beforeEvaluate { project ->
        if (rootProject.hasProperty("userDefinedGradleProperties")) {
            rootProject.ext.userDefinedGradleProperties.each { entry ->
                def propertyName = entry.getKey()
                def propertyValue = entry.getValue()
                project.ext.set(propertyName, propertyValue)
            }
        }

    }
}
// ...

To App_Resources/Android/app.gradle add following (as it does also does in a react native project)

/...
dependencies {
  implementation "com.facebook.react:react-native:+";
}

ns build android (check for errors) ns run android

Log the contents of the com.facebook package on tap event:

//@ts-ignore
for(let key in com.facebook){
    console.log(key);
}

Press TAP ME FOR AN ALERT to log. Note yoga dependency missing in com.facebook

Add maven links to the local react native npm (just like it does in a react native project ):

Which file do you add that to?

my-app/platforms/android/build.gradle. The platforms folders did not make through git to repo

Tried following these steps in my own project and com.facebook just returns undefined :( I'm not going to be able to help much...

It was working for me again in a new rns project

Cool! So still no yoga, but nice to see LayoutEngine (which might in fact call yoga internally) and especially UIManagerModule, ViewManager and ReactViewManager!

I'll keep bashing at it over the next few days to try to get it to build as a modular NativeScript plugin with typings and stuff, rather than something that you add directly to your app.

In the meantime, you might want to play around with creating views and seeing whether you can insert them into the view tree! Would be worth researching what UIManagerModule and ViewManager do – ReactViewManager might help explain that.

Sure I can try that out!

I'm still unable to build it as a plugin – just keep finding com.facebook is undefined.

However, I was at least able to use android-dts-generator to generate TypeScript typings for React Native Android:

https://raw.githubusercontent.com/nativescript-community/react-native-in-nativescript/master/src/typings/java!react-native-0.63.4.d.ts

You'll notice that if you search for module yoga, com.facebook.yoga does actually exist in the typings – so I don't understand why it's not available at runtime.

@Lelelo1 Could you share the whole contents of your my-app/platforms/android/build.gradle and the whole contents of your App_Resources/Android/app.gradle? Trying to understand why your setup isn't working on my side.

A thought occurred to me just now, as to my understanding I’m failing to get the JAR from node_modules/react-native compiled into the app’s runtime... maybe I could try copying that JAR as-is into the plugin (the app’s build script looks for JAR files inside the plugin, so it would pick that up).

The downside is that the plugin would never be able to stay in sync automatically with all future versions of RN (we’d have to regenerate it with each version update), but for a proof of concept plugin, it might be worth a try to get things moving. I’ll give it a go tomorrow if I can.

I think that react-native-0.63.4.aar is the one used, you have that one in react-native/android right?

I think that react-native-0.63.4.aar is the one used, you have that one in react-native/android right?

Yeah, that's the one I was thinking about in this comment:

A thought occurred to me just now, as to my understanding I’m failing to get the JAR from node_modules/react-native compiled into the app’s runtime... maybe I could try copying that JAR as-is into the plugin (the app’s build script looks for JAR files inside the plugin, so it would pick that up).

To generate the typings, I actually entered your gradle settings into android-dts-generator and let it handle the rest. Hope it's exactly the same as react-native-0.63.4.aar in practice. Either way, it generated over 800 KB of Java classes and 2 MB of TypeScript typings, so there's clearly a lot of stuff inside the thing it built.

I'ts a bit to hard to comprehend what happens and what should happen, but we might figure something good out

I've been trying to build it as a plugin here: https://github.com/nativescript-community/react-native-in-nativescript

Could you try running my project? Wondering whether your environment works better than mine.

git clone https://github.com/nativescript-community/react-native-in-nativescript.git  --recursive
cd react-native-in-nativescript
npm install
npm run setup
npm run build
cd demo-react
tns build android
# Or go into Android Studio and run the app to get full error logs
tns run android --no-hmr

On my side I'm getting JNI errors from React Native at startup; I can't get as far as logging out com.facebook anymore:

E/ipt.reactnativ: JNI ERROR (app bug): attempt to pass an instance of java.lang.String as argument 1 to org.json.JSONObject com.facebook.react.uimanager.ViewHierarchyDumper.toJSON(android.view.View)

...

Forget about cloning my project. I've just cloned your project and found yours to be working as you've described, so I compared to mine.

I wasn't able to run yours successfully with the files you've committed so far (I think you've committed some build files). I had to run tns clean.

I decided to try each of your changes individually (the changes to my-app/platforms/android/build.gradle, App_Resources/Android/app.gradle, and the npm install of react-native).

I found that:

I did not need to install the react-native npm package.
I did not need to change my-app/platforms/android/build.gradle.
I did need to change App_Resources/Android/app.gradle.

The result:

JS: binaryresource
JS: cache
JS: common
JS: catalyst
JS: react
JS: csslayout
JS: datasource
JS: drawable
JS: drawee
JS: imagepipeline
JS: fbcore
JS: imageformat
JS: imageutils
JS: infer
JS: jni
JS: perftest
JS: proguard
JS: quicklog
JS: soloader
JS: stetho
JS: systrace

So this is the worrying thing. I think NativeScript is totally ignoring your changes to the .gradle files that tell it to build React Native from node_modules. Instead, I believe it's downloading this old build of react native from 2015: https://mvnrepository.com/artifact/com.facebook/react.

I've not had any luck building from the AAR in node_modules/react-native. I'll try to find a way to confirm what exact version of the React Native lib is being included into your app and my app.

I’ve had a thought. As I’m unsure whether your setup is installing the AAR from node_modules or from maven, maybe the simplest way to check would be to print out the React Native version number by console log.

If you search through my typings file for the term “version”, there are only a small number of mentions. See if you can call an API to print out the version number for the build of React Native that your app is running :)

https://raw.githubusercontent.com/nativescript-community/react-native-in-nativescript/master/src/typings/java!react-native-0.63.4.d.ts

Maybe:

console.log(com.facebook.react.BuildConfig.VERSION_NAME);
console.log(com.facebook.react.BuildConfig.VERSION_CODE);

There’s also this, if I’ve copied it correctly:

console.log(com.facebook.react.modules.systeminfo.ReactNativeVersion.VERSION);

About those version info namespaces they don't appear to correspond to the current react-native repo completely. There could som reasons to it and I don't know yet how frequently it is.

However in the App_Resources, try:

dependencies {
  implementation "com.facebook.react:react-native:version"; // + -> version
}

You will see gradle log redlines trying to find react-native.jar on the local file system. And try to get .pom from remote.

I don't know what the + means though, it is what is present in react native project

About those version info namespaces they don't appear to correspond to the current react-native repo completely. There could som reasons to it and I don't know yet how frequently it is.

I think that suggests that the version of React Native that this repo installs is much older than v0.63.4, which the typings were generated for.

Note that when you ran this code, it logged multiple mentions of BuildConfig, which I'd expect to include a VERSION_NAME and VERSION_CODE:

// This function handles arrays and objects // https://stackoverflow.com/questions/2549320/looping-through-an-object-tree-recursively
function eachRecursive(obj) // com.facebook
{
    for (var k in obj)
    {
        if (typeof obj[k] == "object" && obj[k] !== null)
            eachRecursive(obj[k]);
        else
            console.log(k);
    }
}

So could you try running this to get the full key paths for everything in com.facebook and see whether VERSION_NAME or VERSION_CODE appear?

const visitedValues = new Set();

function eachRecursive(path, value){
    if(visitedValues.has(value)){
        // Crude protection against following circular references in an infinite loop
        console.log(`${path} [Already visited, so won't recurse]`);
        return;
    }
    visitedValues.add(value);
    for(let key in value){

You will see gradle log redlines trying to find react-native.jar on the local file system. And try to get .pom from remote.

When you mentioned this on Slack, you reported that it searched in these locations:

Could not find com.facebook.react:react-native:.
Searched in the following locations:

I should note that it didn't look in node_modules/react-native at all, so indeed, I think this is downloading from the outdated online repo.

You are probably correct that it downloads from outdated online repo.

If you look into are react native project though. The lines have to do something:

// ...
       maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android")
        }
        maven {
            // Android JSC is installed from npm
            url("$rootDir/../node_modules/jsc-android/dist")
        }

Actually those urls are not added unless being placed inside the App_resources/Android/app.gradle:

allprojects {
    repositories {
        google()
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android/one")
        }
        maven {
            // Android JSC is installed from npm
            url("$rootDir/../node_modules/jsc-android/dist/two")
        }
    }
}
android {
  defaultConfig {
    minSdkVersion 17
    generatedDensities = []
  }
  aaptOptions {
    additionalParameters "--no-version-vectors"
  }
}

dependencies {
  implementation "com.facebook.react:react-native:version";
}

It will then look in two extra places: (in */one and */two folders)

Now it uses local react native version 0.63.4. I noticed using 0.63.4 it would not work before but it builds now without errors

So it is now possible to log:

console.log(com.facebook.react.modules.systeminfo.ReactNativeVersion);

{patch=4, major=0, minor=63, prerelease=null}

Okay, trying on my project now.

with the repositories specified in demo-react/App_Resources/Android/app.gradle. We're using maven { url("$rootDir/../../node_modules/react-native/android") } but not specifying the extra maven field about jsc-android.

To be clear, that's this:

allprojects {

        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm

  }
  aaptOptions {
    additionalParameters "--no-version-vectors"
  }
}

dependencies {

Encouraging to see this line during the very brief build output:

It's different! I've got yoga this time!!

I've logged out all the runtime APIs (at least, all the ones I could find using my hasty recursive function):

https://gist.github.com/shirakaba/41492e23f7610609163ecec40f16d89b

🙂

The NativeScript runtimes team told me that, at least for iOS, though, that some of the APIs are lazy-loaded. So they may not all appear just by iterating over the objects – you'd have to call the selectors exactly to make them appear.

Still, though:

console.log(com.facebook.react.modules.systeminfo.ReactNativeVersion.VERSION);
console.log(com.facebook.react.BuildConfig.VERSION_NAME);
console.log(com.facebook.react.BuildConfig.VERSION_CODE);

... prints:

JS: {patch=4, major=0, minor=63, prerelease=null}
JS: 1.0
JS: 1
