FirebasePerformance.getInstance() is crashing on instrumented unit tests

[MrHadiSatrio]

Describe your environment

• Android Studio version: 2020.3.1 Patch 3 (Arctic Fox)
• Firebase Component: Performance
• Component version: 20.0.0 (usage through BOM 28.0.0)

Describe the problem

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.

Any update on this? tried with all latest version(s) and still the same issue.

It breaks all Compose Layout tests in Library modules 😿

[Flyktsodan]

A temporary (not so much) workaround we have implemented is to add a separate manifest in the androidTest folder that removes the plugin.

`

<application android:theme="@style/Theme.AppCompat.Light">

    <!--
        Disables the Firebase Performance plugin for android tests.
        There is a issue where the plugin will crash Instrumented
        tests in Library modules when the application is created.

        See: https://github.com/firebase/firebase-android-sdk/issues/3114 for more info
    -->
    <provider
        android:name="com.google.firebase.perf.provider.FirebasePerfProvider"
        android:authorities="${applicationId}.firebaseperfprovider"
        tools:node="remove" />

</application>

This should have been fixed over a year ago by #4242 can you please try the latest version of Perf and open a new issue if the problem persists, thanks!
