🔥 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
