I set up a firebase project with crashalytics and I can see Java and NDK crashes on the Dashboard. I am trying to upload symbols as per https://firebase.google.com/docs/crashlytics/ndk-reports#upload_native_symbols. I also tried following blogs like https://medium.com/@aungkyawmyint_26195/setting-up-ndk-crashlytics-android-11ad775676f7, but have been unsuccessful so far.

Here is my environment

Android Studio 3.5
Build #AI-191.8026.42.35.5791312, built on August 8, 2019
JRE: 1.8.0_202-release-1483-b49-5587405 x86_64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
macOS 10.14.6

implementation 'com.google.firebase:firebase-analytics:17.2.0'
implementation 'com.crashlytics.sdk.android:crashlytics:2.10.1'
implementation 'com.crashlytics.sdk.android:crashlytics-ndk:2.1.0'

When I run

./gradlew crashlyticsUploadSymbolsDebug --stacktrace

with below in my app/build.gradle

crashlytics {
    enableNdk true
    androidNdkOut 'build/intermediates/cmake/debug/obj'
    androidNdkLibsOut 'build/intermediates/cmake/release/obj'
    manifestPath 'src/main/AndroidManifest.xml'
}

I get the following error

    I'm getting this same issue, it was working fine a few weeks ago and then today as I'm preparing to push a new build I started getting this. Nothing has changed around my crashlytics implementation, so i'm a little confused. – Nathan F. Sep 18 '19 at 17:30
  • Harkish and @Nathan F.: Did you happen to upgrade either your version of the Fabric gradle plugin or your version of Android Studio before this started happening? – Kevin Kokomani Sep 18 '19 at 20:37
  • In my case, this seemed to have been due to the addition of a new library in the `jniLibs` directory. I'm unsure if this actually fixed the problem or if it just made it not come up in the logs anymore, but manualy defining `androidNdkLibsOut` in my `crashlytics` gradle section seemed to fix it. `androidNdkLibsOut 'build/intermediates/cmake/release/obj/'` Again, i'm not sure if this is the proper fix, it just got my symbols *apparently* uploading again. But it looks like you already have that. – Nathan F. Sep 18 '19 at 20:49
  • @KevinKokomani I am evaluating Firebase Analytics and Crashlytics for a project, so I do not have a prior known working version. But results are the same in Linux/Mac and they have all the latest Android Studio versions. The test project linked above was created using Android Studio C++ app wizard. – Harkish Sep 18 '19 at 21:37
  • I tried different versions of Gradle and gradle plugin as per https://developer.android.com/studio/releases/gradle-plugin, changing from the pair 5.4.1/3.5.0 to pair 5.1.1/3.4.0 fixes one problem, ie I no longer need to specify the obj and lib directory, but it still gives me "Crashlytics Developer Tools error" and I am unable to upload my symbols – Harkish Sep 19 '19 at 18:52
  • @NathanF. and Harkish: Crashlytics just released a new version that should address this, check my answer. – Kevin Kokomani Sep 20 '19 at 20:36
  • Firebase support told me they have a fix for this in fabric plugin 1.31.1. It looks like this partly fixes the problem in that, one now does not have to specify the libs and obj directory explicitly. It still does not upload the generated symbols though – Harkish Sep 20 '19 at 21:04

Fabric/Firebaser here -

Version 1.31.1 of the Fabric Gradle plugin has just been released, which should fix the specified for property '$2' does not exist error.

  • HUZZAH! It's working again. I wonder if it was the bug report i filed with them that brought it to their attention. – Nathan F. Sep 20 '19 at 21:03

  • I'm seeing this with android gradle plugin 3.5.2, fabric gradle plugin 1.31.2, and gradle 6.0. Will investigate and post here when/if I find the solution – Carmen Nov 19 '19 at 15:41

    1.31.2 shouldn't have changed anything related to this, so if you're getting the exact same error, I wonder if it's possible changes were made to AGP 3.5.2 that affect the Fabric Gradle plugin. Would be interested to hear more! – Kevin Kokomani Nov 19 '19 at 15:45
  • Still no solution, but here's an update: ``` $ ./gradlew :app:crashlyticsGenerateSymbolsDebug ... Some problems were found with the configuration of task ':app:crashlyticsGenerateSymbolsDebug' (type 'DefaultTask'). > Directory '/path/to/project/app/build/outputs/ndkSymbols/libs' specified for property '$2' does not exist. > Directory '/path/to/project/app/build/outputs/ndkSymbols/obj' specified for property '$1' does not exist. ``` gradle/agp/fabric combos: 6.0 / 3.5.2 / 1.31.2: error 6.0 / 3.5.2 / 1.31.1: error 6.0 / 3.5.1 / 1.31.1: error 5.6.4 / 3.5.1 / 1.31.1: error – Carmen Nov 19 '19 at 16:07
  • Hmmm...might need more info to dig into this more, because that looks like the same error as in the OP that was fixed with Fabric Gradle plugin 1.31.1. If you're able to send over your Gradle build logs as well as all the other info you have to support@fabric.io we'd be more than happy to dig in deeper :) – Kevin Kokomani Nov 19 '19 at 16:11

    Turns out the problem was on our end. Our `app/build/outputs/ndkSymbols` folder was empty. This is the folder we've configured with crashlytics: `androidNdkOut "$buildDir/outputs/ndkSymbols/obj"`, `androidNdkLibsOut "$buildDir/outputs/ndkSymbols/libs"`. After correcting this, I confirm gradle 6.0, agp 3.5.2, fabric 1.31.2 work – Carmen Nov 19 '19 at 16:55

this is Aung Kyaw Myint from blog post.

Firebase is in the middle of migrating for Fabric crashlytics. I've already reported the bugs in the library and documentation. It's being processed.

It also happened to me when I upgraded to latest version. Can you try using these versions:

  1. google-services : 4.2.0
  2. fabric:gradle : 1.31.0
  3. firebase-core: 16.0.9
  4. firebase-crashlytics: 16.0.9

Even when you want Firebase alone, you still need to specify your obj locations which might be varied depending on use case. In my case, it is:

androidNdkOut “build/intermediates/cmake/{flavour}/{buildVariant}/obj”

androidNdkLibsOut “build/intermediates/transforms/mergeJniLibs/{flavour}/{buildVariant}/obj”

Make sure that the obj is inside specified folders.
