App Trace技术解析：传参安装、一键拉起与快速安装

// Android示例：在Application类中获取安装参数
public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        
        // 获取referrer参数（Google Play）
        String referrer = getIntent().getStringExtra("referrer");
        
        // 或者处理自定义scheme的深度链接
        if (getIntent().getData() != null) {
            String source = getIntent().getData().getQueryParameter("utm_source");
            String campaign = getIntent().getData().getQueryParameter("utm_campaign");
            // 保存到SharedPreferences或发送到服务器
        }
    }
}

// 处理Universal Links或URL Scheme
func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
    guard userActivity.activityType == NSUserActivityTypeBrowsingWeb,
          let url = userActivity.webpageURL else {
        return false
    }
    
    // 解析URL中的追踪参数
    let components = URLComponents(url: url, resolvingAgainstBaseURL: true)
    // 处理参数并保存
    return true
}

# Android测试深度链接
adb shell am start -W -a android.intent.action.VIEW -d "myapp://open/product/123" com.example.myapp

# iOS测试Universal Links
xcrun simctl openurl booted "https://example.com/open/product/123"
