Question

I am new to firebase and try to implement firebase in next project. I included dependencies as below but it shows the above error. I would be grateful if anyone can provide information.

My builder.gradle(app)files is as follows:

dependencies {

    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    implementation 'androidx.core:core-ktx:1.3.2'
    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'com.google.android.material:material:1.2.1'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
    implementation 'androidx.navigation:navigation-fragment-ktx:2.2.2'
    implementation 'androidx.navigation:navigation-ui-ktx:2.2.2'

    implementation 'com.google.firebase:firebase-analytics'
    implementation 'com.google.firebase:firebase-firestore'

    testImplementation 'junit:junit:4.+'
    androidTestImplementation 'androidx.test.ext:junit:1.1.2'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}
apply plugin: 'com.google.gms.google-services'

When you integrate Firebase into your app, you must choose one of two ways of adding dependencies, according to the documentation. You can either choose to use specific versions of each dependency, like this:

    implementation 'com.google.firebase:firebase-analytics:18.0.0'
    implementation 'com.google.firebase:firebase-firestore:22.0.0'

Or, you can use the Firebase BoM to choose them for you, based on a single BoM version that applies specific compatible versions for you:

    // Import the Firebase BoM
    implementation platform('com.google.firebase:firebase-bom:26.1.0')

    // versions for Firebase SDKs are chosen automatically by the BoM
    implementation 'com.google.firebase:firebase-analytics'
    implementation 'com.google.firebase:firebase-firestore'

It looks like you tried to use the BoM, but didn't add a line for choosing the platform.

You need to specify explicit version numbers like you did it for the other dependencies. For example:

implementation 'com.google.firebase:firebase-analytics:18.0.0'
implementation 'com.google.firebase:firebase-firestore:22.0.0'

Here you can find more information about the firebase versions --> https://firebase.google.com/support/release-notes/android

I was getting the same error when implementing some Compose UI tests. For me the problem was that the androidTestImplementation configuration did not actually have the firebase dependency.

Solved by adding

androidTestImplementation("com.google.firebase:firebase-messaging-ktx")

to the build.gradle, along with the previously present

implementation("com.google.firebase:firebase-messaging-ktx")

This does not actually make sense, according to this post. Worked for me though.
