# 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:
```bash
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

| Tool | Required Version | How to Check | Platform |
|------|-----------------|--------------|----------|
| **Node.js** | >=22 | `node -v` | All |
| **Yarn** | 4.12.0 | `yarn -v` | All |
| **Java/JDK** | 17+ | `java -version` | All |
| **Gradle** | 8.13 | `./gradlew --version` | All |
| **Go** | 1.24.0 | `go version` | All |
| **Ruby** | 2.7+ (recommended 3.x) | `ruby -v` | macOS only |
| **CocoaPods** | 1.16.2 | `pod --version` | macOS only |
| **Xcode** | 26.2 | `xcodebuild -version` | macOS only |
| **Android Studio** | Ladybug (2024.2.1)+ | Android Studio > About | All |

## Minimum Platform Version Summary

| Platform | Minimum Version | Notes |
|----------|----------------|-------|
| **Android** | API 24 (Android 7.0 Nougat) | Set by Expo SDK |
| **iOS** | 15.5 | Deployment target |
| **Chrome Extension** | Chrome 111+ | Required for MAIN world injection |
| **Firefox Extension** | Latest stable | Follows Chrome manifest v2 |
| **Desktop (Electron)** | Electron 39.x | See OS requirements below |
| **macOS** | 10.15+ (Catalina) | Electron 39 requirement |
| **Windows** | Windows 10+ | Electron 39 requirement |
| **Linux** | Ubuntu 20.04+ | Electron 39 requirement |

## 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**:
```bash
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**:
```bash
grep "platform :ios" apps/mobile/ios/Podfile
```

**Configuration**:
```ruby
platform :ios, podfile_properties['ios.deploymentTarget'] || '15.5'
```

Can also verify in Xcode project:
```bash
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**:
```bash
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**:
```bash
grep '"electron":' apps/desktop/package.json
```

**Current version**: Electron 39.5.1

**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:
```bash
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`

## Quick Environment Check Script

### For macOS (Full check including iOS tools)
```bash
echo "=== Development Environment Check (macOS) ===" && \
echo "OS: $(uname -s) $(uname -r)" && \
echo "Node.js: $(node -v 2>/dev/null || echo 'NOT INSTALLED')" && \
echo "Yarn: $(yarn -v 2>/dev/null || echo 'NOT INSTALLED')" && \
echo "Java: $(java -version 2>&1 | head -1 || echo 'NOT INSTALLED')" && \
echo "Go: $(go version 2>/dev/null || echo 'NOT INSTALLED')" && \
echo "Ruby: $(ruby -v 2>/dev/null || echo 'NOT INSTALLED')" && \
echo "CocoaPods: $(pod --version 2>/dev/null || echo 'NOT INSTALLED')" && \
echo "Xcode: $(xcodebuild -version 2>/dev/null | head -1 || echo 'NOT INSTALLED')" && \
echo "Gradle (configured): $(grep 'distributionUrl' apps/mobile/android/gradle/wrapper/gradle-wrapper.properties 2>/dev/null | sed 's/.*gradle-\(.*\)-bin.zip/\1/' || echo 'N/A')"
```

### For Linux/Windows (Skip iOS-only tools)

echo "Gradle (configured): $(grep 'distributionUrl' apps/mobile/android/gradle/wrapper/gradle-wrapper.properties 2>/dev/null | sed 's/.*gradle-\(.*\)-bin.zip/\1/' || echo 'N/A')" && \
echo "" && \
echo "Note: Xcode, CocoaPods, Ruby are macOS-only (required for iOS development)"
```

### Smart Check (Auto-detect OS)
```bash
if [ "$(uname -s)" = "Darwin" ]; then
  echo "=== macOS Detected - Full Environment Check ===" && \
  echo "Node.js: $(node -v 2>/dev/null || echo 'NOT INSTALLED')" && \

  echo "Java: $(java -version 2>&1 | head -1 || echo 'NOT INSTALLED')" && \
  echo "Go: $(go version 2>/dev/null || echo 'NOT INSTALLED')" && \
  echo "Ruby: $(ruby -v 2>/dev/null || echo 'NOT INSTALLED')" && \
  echo "CocoaPods: $(pod --version 2>/dev/null || echo 'NOT INSTALLED')" && \
  echo "Xcode: $(xcodebuild -version 2>/dev/null | head -1 || echo 'NOT INSTALLED')"
else
  echo "=== Non-macOS Detected - Partial Check ===" && \
  echo "Node.js: $(node -v 2>/dev/null || echo 'NOT INSTALLED')" && \
  echo "Yarn: $(yarn -v 2>/dev/null || echo 'NOT INSTALLED')" && \
  echo "Java: $(java -version 2>&1 | head -1 || echo 'NOT INSTALLED')" && \
