Crashlytics生成符号gradle步骤失败: GC Overhead Limit Exceeded

Question

我正在将一个项目从gradle版本3.3转换为4.10.1。该项目主要是使用自定义构建步骤构建的C++代码，而不是CMake(externalNativeBuild)或Android.mk(ndkBuild)。它产生以下库:

armeabi-v7a unstripped: 883.2MB
arm64-v8a unstripped: 864.6MB
armeabi-v7a stripped: 15.6MB
arm64-v8a stripped: 23.9MB

生成过程在crashlyticsGenerateSymbolsGoogleDistribution步骤失败，出现错误OutOfMemoryError:超出了GC开销限制。

是否有方法或参数可为crashlytics插件步骤提供更多内存？

顶级gradle.properties文件包含以下jvm args: org.gradle.jvmargs=-Xmx4g -XX:MaxPermSize=512m-尽管我已经尝试了 org.gradle.jvmargs=-Xmx12g:MaxPermSize=2g。这些值的任何更改似乎都不会影响crashlyticsGenerateSymbols步骤。

如果我运行一个assembleGoogleDistribution构建，跳过了crashlytics步骤，则该构建将顺利完成。

构建堆栈跟踪:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':application:crashlyticsGenerateSymbolsGoogleDistribution'.
> GC overhead limit exceeded

* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Exception is:

顶级build.gradle

        classpath 'com.google.gms:google-services:4.1.0'

应用程序build.gradle

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
...
crashlytics {
    enableNdk true
    androidNdkOut './../../../build/crashlytics'
    androidNdkLibsOut './../../../build/crashlytics/lib'
}
...
dependencies {
    // Crashlytics Kit
    implementation('com.crashlytics.sdk.android:crashlytics:2.10.1@aar') {
        transitive = true
    }
    // NDK Kit
    implementation('com.crashlytics.sdk.android:crashlytics-ndk:2.1.0@aar') {
        transitive = true
    }
}
...

(我已经确认androidNdkOut路径包含armeabi-v7a和arm64-v8a文件夹，其中包含我们未剥离的libnative.so文件，而androidNdkLibsOut包含与剥离后的libnative.so文件相同的文件夹)

如何确保crashlytics插件为其crashlyticsGenerateSymbols步骤获取了足够的内存，以使其不超过垃圾回收器的开销？

Answer 1

尝试将fabric.properties文件放入具有以下内容的app目录中

disableEnhancedSymbolGeneration=true

它禁用DWARF信息处理，但在映射中保留符号信息。 在这种情况下，您不会在生成的堆栈跟踪中获得文件名和行。仍然会获得完整的函数名称(包括 namespace )，而不是函数地址。
