Crashlytics NDK: No symbols for crashes since update to new sdk

Question

It worked fine until we updated to the new SDK, and now it only shows the last java stack frame on the report. The task uploadCrashlyticsSymbolFileFlavorDebug gets called right after externalNativeBuildFlavorDebug, but no symbols on the reports. I have tried running it by cli after the build, but still no luck. I'm out of ideas and can't find where did I go wrong

Project-Level build.gradle

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.2'
        classpath 'com.google.gms:google-services:4.3.3'
        classpath 'com.google.firebase:perf-plugin:1.3.1'
        classpath 'com.google.firebase:firebase-crashlytics-gradle:2.0.0-beta02'
    }
}

App-Level build.gradle

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
apply plugin: 'com.google.firebase.crashlytics'
apply plugin: 'com.google.firebase.firebase-perf'

android {
    buildTypes {
      release {
         debuggable false
         firebaseCrashlytics {
             nativeSymbolUploadEnabled true
         }
      }
      debug {
         debuggable true
         firebaseCrashlytics {
             nativeSymbolUploadEnabled true
         }
      }
    }
  }

dependencies {
    implementation 'com.google.firebase:firebase-analytics:17.2.3'
    implementation 'com.google.firebase:firebase-crashlytics:17.0.0-beta01'
    implementation 'com.google.firebase:firebase-crashlytics-ndk:17.0.0-beta01'
}
afterEvaluate {
  android.applicationVariants.all { variant ->
    tasks."externalNativeBuild${variant.name.capitalize()}".finalizedBy "uploadCrashlyticsSymbolFile${variant.name.capitalize()}"
  }
}

I've also removed the following line from onCreate

Fabric.with(this.spawner, new Crashlytics(), new CrashlyticsNdk());

EDIT 1 I've checked the debug log to see if everything was working as intended, and it seems to be:

The only strange thing I found was this early line

14:18:56.974 [DEBUG] [com.google.firebase.crashlytics] Mapping File Upload Enabled: false; id: 00000000000000000000000000000000

... but is quickly followed by this one, so i don't think it matters

14:18:57.013 [DEBUG] [com.google.firebase.crashlytics] Crashlytics native symbol uploading enabled: true

Answer 1

Firebaser/Crashlytics team here: To see debugging output of the Firebase Crashlytics NDK SDK I recommend you try the following:

./gradlew app:yourCustomTask --console=plain --debug | grep "\[com.google.firebase.crashlytics\]"

This will show some more output that might help you self-resolve.

Your setup looks correct so far, but it's possible your symbol files were never generated and uploaded to Crashlytics in the first place. I recommend checking out this Firebase documentation on how to provide paths to your stripped and unstripped native libraries: https://firebase.google.com/docs/crashlytics/ndk-reports-new-sdk. Here's the example from the doc:

firebaseCrashlytics {
                nativeSymbolUploadEnabled true
                strippedNativeLibsDir ‘path/to/stripped/parent/dir’
                unstrippedNativeLibsDir ‘path/to/unstripped/parent/dir’
            }

If you're still having trouble feel free to submit a case to Firebase support with the logs from above and all relevant Firebase + Crashlytics setup information for deeper investigation.
