当我使用 Fabric Crashlytics 时问题就出现了,而现在使用 Firebase Crashlytics 最新版本时它仍然存在。一切都基于official NDK docs并且每次构建后都会正确上传符号(cSYM)文件。我设法产生了一个故意的崩溃来比较墓碑和报告的 native 崩溃回溯,结果如下:

报告的 Firebase 控制台崩溃:

通过 Firebase 控制台报告了很多很多崩溃,就像我捕获的那样。其中没有一个具有适当的可用回溯。

任何提示表示赞赏, native 报告目前没有框架是无用的。

编辑:

我已经基于 Kevin's answer 处理了已删除和未删除的 native 库目录如下:
android {
...
buildTypes {
...
release {
firebaseCrashlytics {
nativeSymbolUploadEnabled true
applicationVariants.all { variant ->
firebaseCrashlytics {
strippedNativeLibsDir "build/intermediates/stripped_native_libs/${variant.name}/out/lib"
unstrippedNativeLibsDir "build/intermediates/ndkBuild/${variant.name}/obj/local"
}
}
}
}
}
}

并设法产生了一个崩溃,该崩溃具有一个通过我自己的 native 库的调用堆栈,但问题仍然存在:

编辑2:

我按照 Kevin 的建议使用此命令调试符号文件上传问题(我使用 find /I 而不是 grep,因为我在 Windows 上):
gradlew app:assembleRelease --console=plain --debug | find /I "[com.google.firebase.crashlytics]"

结果是使用 implementation 'com.google.firebase:firebase-iid'连同 implementation platform('com.google.firebase:firebase-bom:25.2.1')是什么让我无法赎回:) 因为显然 Firebase 已经在 com.google.firebase:firebase-messaging 中使用实例 ID 依赖项本身。长话短说,仅使用此配置帮助我正确上传了我的符号:
android {
...
buildTypes {
...
release {
firebaseCrashlytics {
nativeSymbolUploadEnabled true
}
}
}
}

// Upload Crashlytics NDK symbols
tasks.whenTaskAdded { task -> if (task.name.startsWith('assemble') && task.name.endsWith("Release")) task.finalizedBy "uploadCrashlyticsSymbolFile" + task.name.substring('assemble'.length()) }

dependencies {
...
implementation platform('com.google.firebase:firebase-bom:25.2.1')
implementation 'com.google.firebase:firebase-iid:20.1.5'
implementation 'com.google.firebase:firebase-messaging'
...
}

并且至少在我自己的 native 库上获取调用堆栈:

最佳答案

Firebaser在这里-

您粘贴屏幕截图的崩溃报告似乎只发生在系统库中。我们可以在 Crashlytics 崩溃报告(和墓碑)中看到,所有的堆栈帧都与“libc.so”相关联——这是一个 Android 系统运行时库,任何像 Crashlytics 这样的库都无法符号化。

这是因为 Crashlytics 只能表示来自您为其上传符号的库的崩溃或堆栈帧。由于 libc.so 是您和 Crashlytics 都没有其符号的系统库,因此这是预期的行为。 Crashlytics 仍会显示帧,即使它不能象征性地表示它仍在报告尽可能多的信息。

如果您能够提交包含调用堆栈的测试崩溃报告,该调用堆栈通过您尝试上传符号的您自己的 native 库,并且您仍然到处看到“(缺失)”,那将是出乎意料的。如果是这种情况,我建议您确保已关注 these instructions在您链接的文档中,并联系 Firebase support如果您仍有问题。
