Firebase Crashlytics vs Sentry 对比

// Firebase Crashlytics - Android（Kotlin）安装与非致命日志记录
// build.gradle.kts (app)
// plugins { id("com.google.gms.google-services"); id("com.google.firebase.crashlytics") }
// dependencies { implementation(platform("com.google.firebase:firebase-bom:34.19.0"))
//                implementation("com.google.firebase:firebase-crashlytics") }

    private val crashlytics = Firebase.crashlytics

    fun onPaymentStarted(orderId: String, amount: Double) {
        // Breadcrumb：记录操作步骤，便于崩溃时定位所处阶段
        crashlytics.log("payment_started order=$orderId amount=$amount")
        crashlytics.setCustomKeys {

// AndroidManifest.xml：firebase_crashlytics_collection_enabled=false（获得用户同意后再开启）
// Runtime：Firebase.crashlytics.setCrashlyticsCollectionEnabled(true)

// Sentry - iOS（Swift）：单一 SDK 集成错误 + 性能 + 会话回放
// Package.swift / SPM: https://github.com/getsentry/sentry-cocoa

        // 出错时自动附加截图 + 视图层级信息
        options.attachScreenshot = true
        options.attachViewHierarchy = true
    }
}

// Breadcrumb + 自定义上下文 + 非致命错误捕获
func onPaymentFailed(_ error: Error, orderId: String) {
    let crumb = Breadcrumb(level: .error, category: "payment")
    crumb.message = "payment_failed order=\(orderId)"
    SentrySDK.addBreadcrumb(crumb)
