🔥 ZikZak UserAgent Android 🔥

Native Android UserAgent Extraction with WebView Precision

The Android implementation of zikzak_useragent that leverages Android WebView to extract authentic Chrome/WebView UserAgent strings with surgical precision.

WHAT IT DOES

This package provides the Android-specific implementation for extracting native UserAgent strings using Android WebView's settings. No compromises. No "good enough" solutions.

TECHNICAL IMPLEMENTATION

Kotlin Implementation

  • WebView Integration: Direct access to webView.settings.userAgentString
  • Async Result Handling: Flutter-compliant async result callbacks
  • Memory Efficient: Lazy WebView initialization
  • Context Aware: Application context-based WebView creation

UserAgent Format

Mozilla/5.0 (Linux; Android 14; Pixel 8) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Mobile Safari/537.36

REQUIREMENTS

  • Android: API Level 19+ (Android 4.4)
  • Kotlin: Latest stable
  • Android SDK: 33+
  • Flutter: >=3.19.0

INTEGRATION

This package is automatically included when you add zikzak_useragent to your pubspec.yaml. The Android implementation registers itself automatically:

// Automatic registration
ZikzakUserAgentPlatform.instance = ZikzakUserAgentAndroid();

METHOD CHANNEL

  • Channel Name: zikzak_useragent
  • Method: getPlatformUserAgent
  • Return Type: String

KOTLIN PLUGIN DETAILS

Class: ZikzakUserAgentPlugin

  • Implements: FlutterPlugin, MethodCallHandler
  • Registration: onAttachedToEngine with FlutterPluginBinding
  • WebView: Instance variable for UserAgent extraction
  • Method Handling: Switch-based method call routing

WebView UserAgent Extraction

override fun onMethodCall(call: MethodCall, result: Result) {
    if (call.method == "getPlatformUserAgent") {
        val userAgent = webView?.settings?.userAgentString
        result.success(userAgent)
    } else {
        result.notImplemented()
    }
}

WEBVIEW INITIALIZATION

override fun onAttachedToEngine(flutterPluginBinding: FlutterPlugin.FlutterPluginBinding) {
    channel = MethodChannel(flutterPluginBinding.binaryMessenger, "zikzak_useragent")
    channel.setMethodCallHandler(this)
    webView = WebView(flutterPluginBinding.applicationContext)
}

ERROR HANDLING

  • Null Safety: Safe handling of potential null WebView
  • Context Errors: Application context ensures proper WebView creation
  • Method Errors: result.notImplemented() for unknown methods
  • Memory Management: Proper cleanup in onDetachedFromEngine

PERFORMANCE

  • Lazy Initialization: WebView created only when needed
  • Memory Efficient: Minimal footprint implementation
  • Context Optimized: Application context for lifecycle management
  • Thread Safe: Flutter-compliant async patterns

PERMISSIONS

No special Android permissions required. WebView UserAgent is accessible without additional permissions.

TESTING

Android implementation testing via Flutter integration tests:

testWidgets('getPlatformUserAgent test', (WidgetTester tester) async {
  final ZikzakUserAgent plugin = ZikzakUserAgent();
  final String? userAgent = await plugin.getPlatformUserAgent();
  expect(userAgent?.isNotEmpty, true);
});

GRADLE CONFIGURATION

Standard Flutter plugin configuration - no additional Gradle setup required.

COMPATIBILITY

  • Android Versions: 4.4+ (API 19+)
  • WebView: System WebView and Chrome Custom Tabs
  • Architecture: ARM, ARM64, x86, x86_64
  • Flutter Versions: 3.19.0+

CHANGELOG

v1.1.0 - ZIKZAK Refactor

  • ✅ Rebranded from webview_useragent_android
  • ✅ Updated class names: WebviewUserAgentPlugin → ZikzakUserAgentPlugin
  • ✅ Enhanced method channel naming
  • ✅ Improved Kotlin code structure
  • ✅ Package path reorganization
