Crashlytics could not parse the Android Project structure

Question

I have connected my Android app to crashlytics. My project has 3 flavors. The fabric key I've added to the main AndroidManifest.xml which is common for all 3 flavors. But when I'm trying to build apk file it return error:

:app:fabricGenerateResourcesKzDebug
ERROR - Crashlytics Developer Tools error.
java.lang.IllegalArgumentException: Crashlytics could not parse the Android Project structure. 

The gradle of my project for flavors is next:

    flavorDimensions("build")

    productFlavors {
        kz {
            dimension "build"
        }
        ua {
            dimension "build"
        }
        uz {
            dimension "build"
        }
    }
    compileOptions {
        targetCompatibility 1.8
        sourceCompatibility 1.8
    }

The whole error of my build:

Starting a Gradle Daemon, 1 incompatible and 3 stopped Daemons could not be reused, use --status for details

I'm novice in working with flavors so maybe the problem is here (actually I don't know). However, I am stuck.

My project structure:

Answer 1

I've had the same error after restructuring the resources of my flavors.

You have to make sure that every flavor has a res folder inside it. Even if the flavor has no own resources. After adding some empty folders the build did succeed again.

Example:

/App
  /src
    /flavor1
       /res <--
    /flavor1Release
       /res <--
    /flavor2
       /res <--
    /main
       /res <--

Answer 2

The solution for me was this:

1. To hard code the fabric key in the AndroidManifest.xml rather than referencing it as a string in the strings.xml file.
2. To add an empty "res" folder inside my "main" folder.
