Crashlytics found an invalid API key: null.

Step 1: Describe your environment

• Android device: _Samsung s8
• Android OS version: 9
• Google Play Services version: 4.3.3
  implementation 'com.firebaseui:firebase-ui-auth:4.3.2'
  implementation 'com.firebaseui:firebase-ui-storage:4.3.2'
  implementation 'com.google.firebase:firebase-core:17.2.1'
  implementation 'com.google.firebase:firebase-storage:19.1.0'
  implementation 'com.google.firebase:firebase-database:19.2.0'
  implementation 'com.google.firebase:firebase-auth:19.1.0'
  implementation 'com.google.firebase:firebase-messaging:20.0.1'
  implementation 'com.google.firebase:firebase-dynamic-links:19.0.0'
  implementation 'com.crashlytics.sdk.android:crashlytics:2.10.1'

Step 2: Describe the problem:

If I try to run an instrument test I get the following error:
Crashlytics found an invalid API key: null.

Steps to reproduce:

Install firebase crashlytics. Run Instrument Test.

Observed Results:

Crashlytics found an invalid API key: null.

Expected Results:

Test to run

Relevant Code:

@RunWith(AndroidJUnit4::class)
@SmallTest
class ExampleInstrumentedTest {


    @Test
    fun useAppContext() {
        // Context of the app under test.
        val appContext = InstrumentationRegistry.getInstrumentation().context
        assertEquals("com.mypackage", appContext.packageName)
    }
}

@paulsUsername this sounds a bit like this issue:
https://stackoverflow.com/questions/52614015/invalid-crashlytics-api-key-error-when-upgrading-to-android-gradle-plugin-3-3-0

Could you show me your build.gradle and app/build.gradle files in full so I can see if anything sticks out?

[paulsUsername]

Really sorry about the delay getting back to you. It's causing a lot of problems now. The only way we can release new builds, otherwise, we get:

No value has been specified for this provider.

Completely removing crashlytics resolves the issue

Further information:

If I downgrade Gradle to 'com.android.tools.build:gradle:3.5.1' it resolves to issue. Any version past that and it won't work If I have crashlytics as part of the project. With Crashlytics removed from the project, I can sync perfectly with any gradle version.

[paulsUsername]

This is still causing major headaches here. We have to completely remove Crashlytics in order to run a test

[samtstern]

@paulsUsername sorry about my slow response here. So it looks like this is an incompatibility between two things:

• com.android.tools.build:gradle:3.6.0-beta04
• io.fabric.tools:gradle:1.31.2

I have to be honest that I am not familiar enough with the fabric plugin (or the AGP beta) to debug this myself but let me try to find someone on the Crashlytics team who can.

[kevinkokomani]

I tested creating a brand new Fabric project with 3.6.0-beta05 and was able to onboard a fresh Fabric app - does this resolve the issue for anyone else?

[kevinkokomani]

@paulsUsername We were able to get this working with 3.6.0-beta05 and 3.6.0-beta04. We found that integrating Firebase Crashlytics with a fresh app, and making sure to include the right google-services.json file as well as the google-services dependency in the build.gradle, resulted in no errors.

Are you doing anything custom with your setup in terms of how you add your google-services.json file?

[paulsUsername]

It seemed to resolve that initial error in regards to Crashlytics API key but I am get a provider error then.

“No value has been provided for this provider”

There is no clarity provided on which producer this refers to.

Nothing fancy with our google services json.

[paulsUsername]

I meant to follow on from the above. The issue wasn't actually resolved, we were using an earlier version of Gradle. Anything past 3.5.1 returns error:

“No value has been provided for this provider”

The only way to resolve the issue on 3.6.0-rc01 is to remove the line:

apply plugin: 'io.fabric'

[kevinkokomani]

Hey, sorry for the delay here. I was wondering if you'd be able to share the full stacktrace for the issue you're seeing here? Can you run

./gradlew clean assembleDebug --stacktrace

and attach the output? Thanks!

For visibility, we're still unable to reproduce this behavior, so we'd like a better idea of exactly what's going on so we can try to build a reproduction case.

[samtstern]

Since there has been no response in a while I assume this bug has been fixed. @paulsUsername if that is not the case I am happy to re-open it
