Local Environment Setup

1. Clone the repository

Prerequisites:

• Install Java SDK v14.*

• Install the development environment React Native 0.69.3

• Configure Java environment variables:

  • JAVA_HOME
  • PATH

• Install Android Studio. It should be used with Java SDK v14, mentioned in the first step.

• Generate an emulator in Android Studio

• Open the project with the selected editor

• Open a terminal and execute:

Install dependencies:

cd source
yarn 
yarn postinstall

• Modify: The file: node_modules\react-native-os\android\build.gradle Line 47: change 'compilation' to 'implementation'

Environment Variables

• Configure your variables in the file /source/src/config/agent.ts

Start the app

yarn android

Running on macOS with M Chips

To run the project on macOS with Apple Silicon (M1, M2, M3) chips, follow these additional steps:

1. Use Node.js version 18:

nvm use 18

2. Set up Android SDK path:

cd android
touch local.properties

Add the following line to local.properties:

sdk.dir = /Users/YOUR_USERNAME/Library/Android/sdk

Replace YOUR_USERNAME with your macOS username.

3. Fix JFrog download URL issue by installing patch-package:

npm install --save-dev patch-package postinstall-postinstall

4. Fix the React Native boost download URL:

   Edit the file: node_modules/expo-modules-core/android/build.gradle

   Replace the JFrog URL with the archives.boost.io URL:

   Change:

   def srcUrl = REACT_NATIVE_TARGET_VERSION >= 69
     ? "https://boostorg.jfrog.io/artifactory/main/release/${BOOST_VERSION.replace("_", ".")}/source/boost_${BOOST_VERSION}.tar.gz"
     : "https://github.com/react-native-community/boost-for-react-native/releases/download/v${BOOST_VERSION.replace("_", ".")}-0/boost_${BOOST_VERSION}.tar.gz"
   

   To:

   def srcUrl = REACT_NATIVE_TARGET_VERSION >= 69
     ? "https://archives.boost.io/release/${BOOST_VERSION.replace("_", ".")}/source/boost_${BOOST_VERSION}.tar.gz"
     : "https://github.com/react-native-community/boost-for-react-native/releases/download/v${BOOST_VERSION.replace("_", ".")}-0/boost_${BOOST_VERSION}.tar.gz"
   

   Additionally, if you find it and update:

   def srcUrl = "https://boostorg.jfrog.io/artifactory/main/release/${transformedVersion}/source/boost_${BOOST_VERSION}.tar.gz"
   

   To:

   def srcUrl = "https://archives.boost.io/release/${transformedVersion}/source/boost_${BOOST_VERSION}.tar.gz"
   

5. Create the patch:

npx patch-package expo-modules-core

6. Clean the Gradle project:

cd android
./gradlew clean
cd ..

7. Launch the Android app:

yarn android

These fixes address the React Native community issues with broken download URLs from JFrog. For more information, see this GitHub issue.
