android - Firebase Crashlytics 不报告崩溃

Question

我已经成功地将 Firebase 集成到我的项目中
(身份验证和存储效果很好)但是在简单集成 Crashlytics 并故意(而不是故意)使我的应用程序崩溃之后 - 没有崩溃报告出现在崩溃仪表板中。
我确实在 Logcat 中看到:
D/FirebaseApp:com.google.firebase.crash.FirebaseCrash 未链接。跳过初始化
I/CrashlyticsCore:Crashlytics 报告上传完成:5BEDB1320329-0001-43...

我已经将 Crashlytics 集成到其他 3 个应用程序中，没有任何问题，但由于某些原因，它在我的新应用程序中不起作用。
谁能想到我错过了什么？

新下载的 google-services.json 文件就位
我添加到项目gradle文件中:

    buildscript {
        repositories {
            maven {
               url 'https://maven.fabric.io/public'
            }
        }
        dependencies {
            classpath 'com.google.gms:google-services:4.2.0'
            classpath 'io.fabric.tools:gradle:1.26.1'
        }
    }

    allprojects {
        repositories {
           // ...
           maven {
               url 'https://maven.google.com/'
           }
        }
    }

and added to the app gradle file:

    apply plugin: 'io.fabric'

    dependencies {
        // ...
        implementation 'com.google.firebase:firebase-core:16.0.5'
        implementation 'com.crashlytics.sdk.android:crashlytics:2.9.6'
    }

Thanks for your thoughts

Update
enabling Crashlytics debug logs shows that the crash was captured and reported but still nothing shows in the project's Firebase Crashlytics dashboard

我遇到了同样的问题，Crashlytics 不报告事件趋势，也不报告 PROD 构建中的崩溃堆栈跟踪。问题出在 Proguard 配置中。听起来很愚蠢，但在 Google 的所有文档中根本没有提到 Proguard。在这里您可以找到我必须添加的内容才能使其正常工作:

# Firebase
-keepattributes *Annotation*
-keepattributes SourceFile,LineNumberTable
-keep public class * extends java.lang.Exception
-keep class com.crashlytics.** { *; }
-dontwarn com.crashlytics.**

我希望这对您和其他许多人有所帮助，我已经花了一周时间调试和尝试我能想到的任何事情。
