GradleException: Crashlytics could not determine stripped/unstripped native library directories - android-studio

Question

There is plenty of "chatter", but I did not find an answer for my project.
While performing the Gradle Sync in my project with Crashlytics, Gradle fails to sync. I have other projects that are just fine and when I 'diff' the build.gradle files and other Android Studio settings, they have the same values and settings related to Crashlytics.
A problem occurred configuring project ':app'.
> org.gradle.api.GradleException: Crashlytics could not determine stripped/unstripped native library directories for project ':app', variant Debug. These are required for generating symbol files when NDK build tasks cannot be automatically inferred. Please specify strippedNativeLibsDir and unstrippedNativeLibsDir in the firebaseCrashlytics extension.
I am not looking for someone to triage my configuration, instead I want to know where in my project files can I find the "firebaseCrashlytics extension" and its configuration and where are the stripped and unstripped files so I can supply a path? If you know the answer from documentation, please share the link.

Answer 1

Make sure your android/app/build.gradle has the following:
release {
// ...
firebaseCrashlytics {
nativeSymbolUploadEnabled true
strippedNativeLibsDir 'build/intermediates/stripped_native_libs/release/out/lib'
unstrippedNativeLibsDir 'build/intermediates/merged_native_libs/release/out/lib'
}
// ...
}

Answer 2

In my case, I had a few projects cloned locally of the same repo. One of them was for a too old branch. Like 3-4 years back. For it, I have given a path to another NDK in the local.properties file.
ndk.dir=C\:\\NDK\\android-ndk-r13b\\android-ndk-r13b
It was causing my problem with the recent branches. After deleting it - it worked. So even if it is not the exact same case for you - it is most likely that you are building with the wrong SDК. Try updating in the SDK manager or maybe actually try explicitly saying what you need as I was doing above.

Answer 3

In my project-level build.gradle, Android Studio recommends updating the the firebase-crashlytics-gradle from 2.1.1 to 2.4.1. When I take the upgrade recommendation, the gradle sync fails, therefore I am unable to build my project. The error was obscured as I inherited this old project that is several versions behind and I updated all (most) of the frameworks and could not pin-point to this single dependency. I started over and upgraded selectively piecemeal until this was the lone down-level dependency.
I will try again at a later time when there is yet another update
to include.
