Mendix React Native Template for Farmworker Wallet OS Project

Native Template - Android

This native template is located in directory source in this source tree.

Tools used:

• npm: 8.19.2
• node: v16.18.0
• java: openjdk 11.0.11 2021-04-20
• javac: javac 11.0.11

Ensure you have NDK installed by using the sdkmanager tool

~/Android/cmdline-tools/tools/bin/sdkmanager --list_installed

If none are installed, select a candidate from the output ...

~/Android/cmdline-tools/tools/bin/sdkmanager --list

... and install a version, e.g.

~/Android/cmdline-tools/tools/bin/sdkmanager --install ndk;23.2.8568313

Using an existing or newly installed version of ndk, edit android/build.gradle ensuring the following

buildscript {
    ext {
        ...
        minSdkVersion = 21
	    //ndkVersion = "23.2.8568313"
        ndkVersion = "25.1.8937393"
        ...
    }
}

Add conditional logic for repo.url

allprojects {
    repositories {
        all { repo ->
            if (repo.hasProperty('url')) {
                println repo.url.toString()
                if (repo.url.toString().contains("jcenter.bintray.com") || repo.url.toString().contains("jitpack.io")) {
                    project.logger.warn "Repository ${repo.url} removed."
                    remove repo
                    google()
                    mavenLocal()
                    mavenCentral()
                }
            }
        }
   ...

Add the Sovrin maven repository to android/build.gradle

allprojects {
    repositories {
        ...
        maven {
            url 'https://repo.sovrin.org/repository/maven-public'
        }
        ...
    }
}

Edit android/app/build.gradle and add JNA as follows

dependencies {
    ...
    //Required by Credo (Formerly Aries Framework JavaScript)
    implementation 'net.java.dev.jna:jna:5.2.0'
    ...
}

For @aries-framework/cheqd to work, the Hermes engine needs to be used instead of JSCore. To do so, ammend android/app/build.gradle as follows

project.ext.react = [
	bundleForVariant: { def variant -> false },
	enableHermes : true
]

def enableHermes = project.ext.react.get("enableHermes", true);

if (enableHermes) {
	implementation("com.facebook.react:hermes-engine:+") {
		exclude group:'com.facebook.fbjni'
	}
} else {
	implementation jscFlavor
}

Be sure to comment out the jsc implementation line

//implementation "org.webkit:android-jsc:r245459

For smaller APK sizes, limit the buildTypes by editing android/app/build.gradle and add abiFilters as follows reference

...
     buildTypes {
        release {
            ...
            ndk {
                abiFilters "armeabi-v7a", "arm64-v8a"
            }
        }
        debug {
            ndk {
                abiFilters "armeabi-v7a", "arm64-v8a"
            }
        }
    }
...

Install the node modules by running the following

npm install --legacy-peer-deps
npm run configure

Native Template - iOS

This native template is located in directory source/prj in this source tree.

Install the node modules by running the following

npm install --legacy-peer-deps
npm run configure

Ensure the following sources are listed in ios/Podfile

source 'https://cdn.cocoapods.org'

For @aries-framework/cheqd to work, the Hermes engine needs to be used instead of JSCore. To do so, ammend ios/Podfile as follows:

  use_react_native!(
    :path => config[:reactNativePath],
    # Hermes is disabled by default to avoid incompatibilities and slowness with Mendix Runtime.
    :hermes_enabled => true,
    :fabric_enabled => false,

Install the pods as follows

cd ios
pod install

Open the project in Xcode using the following

open ./NativeTemplate.xcworkspace
