Fabric crashlytics reports crashes in obfuscated format

问题

I use crashlytics to send my reports but crashs not de-obfuscated like this:

Fatal Exception: c.a

I readed here and added

-keepattributes *Annotation*
-keepattributes SourceFile,LineNumberTable

to my proguard-rules file and there is no

-printmapping mapping.txt

in my configuration files. this is my build.gradle buildTypes part:

buildTypes {
        release {
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

            
        }
        debug_server {
            minifyEnabled false
            debuggable true

            matchingFallbacks = ['release']
        }
        debug {
            applicationIdSuffix '.debug'
            versionNameSuffix '-DEBUG'
            minifyEnabled false

        }

}

not all of my crashes are like this and I updated crashlytics to 2.9.4 version.

UPDATE:

I just skipped this

-keep class com.crashlytics.** { *; }
-dontwarn com.crashlytics.**

as I don't need to skip running proguard on Crashlytics.

UPDATE2: v2.9.9 of crashlytics. Not fixed until now. I can't detect the real cause of bugs.

回答1:

You have to add an extra rule to proguard file to keep all Kotlin exceptions

-keep public class * extends java.lang.Exception

回答2:

I also had the problem.

Have you tried adding firebase-crash?

build.gradle(app level) in dependencies.

apply plugin: 'com.google.firebase.firebase-crash'

android{
   ...
}

and

implementation 'com.google.firebase:firebase-crash:16.2.1'

build.gradle(Proejct level)

    buildscript {
      repositories {
        jcenter()
        // ...
      }

      dependencies {
        // ...
        // For Android Studio 2.x, use firebase-plugins version 1.1.1
        classpath 'com.google.firebase:firebase-plugins:1.1.1'
        // For Android Studio 3.0, use firebase-plugins version 1.1.5
        //classpath 'com.google.firebase:firebase-plugins:1.1.5'
      }
    }

Try this and, if it doesn't solve your problem, let me know.

Plus, using -keep is not recommended.

Alternatively, you can check ANR & Crash on Google Play Console

Go to your app, and open Android vitals > ANR & Crash
