OneKey Platform Requirements

Device Compatibility Check

When user asks if their device can run app-monorepo, run the environment check to verify all required tools are installed with correct versions.

Important: Xcode, CocoaPods, and Ruby are macOS only tools required for iOS development. On non-macOS systems, skip these checks.

Auto-detect and Check Environment

First, detect the operating system:

uname -s

• If output is Darwin → macOS, check ALL tools including Xcode/CocoaPods
• If output is Linux or other → Skip Xcode/CocoaPods/Ruby checks

Development Environment Requirements

Minimum Platform Version Summary

How to Verify/Update Versions

Android minSdkVersion

Location: Set by Expo, referenced in apps/mobile/android/app/build.gradle:142

How to check current value:

cd apps/mobile/android && ./gradlew -q properties 2>&1 | grep -i "minSdk"

Configuration chain:

1. apps/mobile/android/app/build.gradle references rootProject.ext.minSdkVersion
2. Value set by expo-modules-autolinking in ExpoRootProjectPlugin.kt
3. Default is 24 unless overridden in expo version catalog

iOS Deployment Target

Location: apps/mobile/ios/Podfile:18

How to check:

grep "platform :ios" apps/mobile/ios/Podfile

Configuration:

platform :ios, podfile_properties['ios.deploymentTarget'] || '15.5'

Can also verify in Xcode project:

grep "IPHONEOS_DEPLOYMENT_TARGET" apps/mobile/ios/OneKeyWallet.xcodeproj/project.pbxproj | head -5

Chrome Extension Minimum Version

Location: apps/ext/src/manifest/chrome_v3.js:9

How to check:

grep "minimum_chrome_version" apps/ext/src/manifest/chrome_v3.js

Note: Version 111+ is required for MAIN world content script injection (manifest v3 feature).

Firefox Extension

Location: apps/ext/src/manifest/firefox.js

Firefox manifest extends Chrome manifest but may have different requirements. Currently follows Chrome manifest v2 patterns.

Desktop (Electron) Version

Location: apps/desktop/package.json

How to check:

grep '"electron":' apps/desktop/package.json

Current version: Electron 39.3.0

Electron 39 OS Requirements:

• macOS: 10.15+ (Catalina)
• Windows: Windows 10+
• Linux: Ubuntu 20.04+, Fedora 32+, Debian 10+

Reference: Check Electron releases for OS compatibility at https://releases.electronjs.org/

Full SDK Version Check Command

Run this to see all Android SDK versions at once:

cd apps/mobile/android && ./gradlew -q --no-configuration-cache properties 2>&1 | grep -E "(minSdk|compileSdk|targetSdk|buildTools|ndk|kotlin):"

Expected output format:

- buildTools:  36.0.0
- minSdk:      24
- compileSdk:  36
- targetSdk:   36
- ndk:         27.1.12297006
- kotlin:      2.1.20

Version Update Considerations

When updating minimum versions:

1. Android: Expo SDK updates may change minSdkVersion. Check Expo release notes.
2. iOS: Update both Podfile and Xcode project settings.
3. Extension: manifest changes affect all Chromium browsers (Chrome, Edge, Brave, Opera).
4. Electron: Major version bumps may drop OS support. Check Electron release notes.

Development Environment Details

Node.js

Required: >=22

Location: package.json:10-12

How to check configuration:

grep -A2 '"engines"' package.json

Configuration:

"engines": {
  "node": ">=22"
}

Yarn

Required: 4.12.0 (Yarn Berry / Yarn 4)

Location: package.json:3

How to check configuration:

grep '"packageManager"' package.json

Configuration:

"packageManager": "yarn@4.12.0"

Java/JDK

Required: JDK 17+

Why: Gradle 8.13 requires Java 17+. The project uses jvmTarget = "17" for Kotlin compilation.

Location: apps/mobile/android/build.gradle:101

How to check configuration:

grep "jvmTarget" apps/mobile/android/build.gradle

Gradle

Required: 8.13

Location: apps/mobile/android/gradle/wrapper/gradle-wrapper.properties:3

How to check configuration:

grep "distributionUrl" apps/mobile/android/gradle/wrapper/gradle-wrapper.properties

Configuration:

distributionUrl=https\://services.gradle.org/distributions/gradle-8.13-bin.zip

Ruby (macOS only)

Required: 2.7+ (recommended 3.x for Apple Silicon)

Platform: macOS only - required for iOS development

Why: Required for CocoaPods and iOS build tooling.

How to check:

ruby -v

Note: On macOS, system Ruby may be outdated. Use rbenv or rvm to manage Ruby versions.

CocoaPods (macOS only)

Required: 1.16.2

Platform: macOS only - required for iOS development

Location: apps/mobile/ios/Podfile.lock (last line)

How to check configuration:

tail -1 apps/mobile/ios/Podfile.lock

How to install:

gem install cocoapods -v 1.16.2

Go

Required: 1.24.0

Why: Required for compiling gopenpgp cryptographic library on iOS.

Location: apps/mobile/ios/Podfile:33

How to check configuration:

grep "go_version = " apps/mobile/ios/Podfile

Note: Go is auto-installed by Podfile if not present. The gopenpgp XCFramework is pre-built and cached in apps/mobile/ios/XCFrameworks/.

Xcode (macOS only)

Required: 26.2

Platform: macOS only - required for iOS development

Why: Required for building iOS app with latest SDK features and deployment target.

How to check:

xcodebuild -version

Note: Xcode version determines available iOS SDKs and simulator versions.

Android Studio

Required: Ladybug (2024.2.1) or later

Why: compileSdk 36 requires Android Studio with SDK 36 support.

How to check: Android Studio > About Android Studio

Required components:

• Android SDK Platform 36
• Android SDK Build-Tools 36.0.0
• NDK 27.1.12297006
• CMake (for native modules)

Smart Check (Auto-detect OS)

else

  echo "Node.js: $(node -v 2>/dev/null || echo 'NOT INSTALLED')" && \
  echo "Yarn: $(yarn -v 2>/dev/null || echo 'NOT INSTALLED')" && \
