[MrHadiSatrio]

Getting this crash when running instrumented unit tests:

java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process com.hadisatrio.apps.android.repro.test. Make sure to call FirebaseApp.initializeApp(Context) first.

This happened on all tests that uses ActivityScenario#launch(Activity), starting from Performance 20.0.0. Earlier releases worked fine without any code change.

Steps to reproduce:

On an Android project with Firebase Performance setup:

1. Create an empty library module (say. :module)
2. Add a dependency to firebase-perf within the module
3. Create an empty activity
4. Add the test shown below within androidTest directory
5. ./gradlew module:connectedCheck

...or...

1. Download & extract MCVE.zip
2. Add your google_services.json file within :app
3. ./gradlew module:connectedCheck

Relevant Code:

class Repro {

    @Test // This will fail with the above stacktrace
    fun activityScenario() {
        ActivityScenario.launch(MainActivity::class.java).use {
            print(0)
        }
    }

    @Test // This will pass
    fun nonActivityScenario() {
        print(0)
    }
}

Hi @MrHadiSatrio, thanks for reporting. It seems that this issue is replicable when id 'com.google.gms.google-services' is not added in your build.gradle file.

build.gradle in app module:

plugins {
    id 'com.android.application'
    id 'kotlin-android'
    id 'com.google.gms.google-services'
}

build.gradle in project:

dependencies {
    classpath "com.android.tools.build:gradle:7.0.1"
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.30"
    classpath 'com.google.gms:google-services:4.3.10'
}

Could you check if adding these work? Thanks.

[MrHadiSatrio]

@argzdev, adding the plugin did not solve the problem for me; the tests still fail with an identical stack trace.

The only thing that worked was disabling FirebasePerfProvider through tools:remove in the Manifest. (A similar finding also posted here.)

Hi @MrHadiSatrio, thanks for the details. I was able to repro the issue, I'll try to get in contact with an engineer and see what we can find.

@MrHadiSatrio I tried reproducing the issue based on the steps you provided. But unfortunately I'm not able to do the same. I'm sure there is something I have missed. Can you please help me reproduce the issue?

Here is my sample project. Please make sure to add your google_services.json file to make sure you are able to move ahead on this.

If there are any changes pending, please let me know.

[MrHadiSatrio]

@visumickey, I was able to repro it on your sample project. Could you try adding the dependency to firebase-perf within :module and re-run the test?

I'll edit my initial post to include this in the STR.
