Hi @jiayuliang1314, thank you for reaching out. I tried reproducing the issue, however I did not encounter any error.

Below is the dependency I used:

build.gradle.kts

    alias(libs.plugins.android.application) apply false    //agp = "8.11.1"
    alias(libs.plugins.kotlin.android) apply false    //kotlin = "2.2.0"
    alias(libs.plugins.google.gms.google.services) apply false   //googleGmsGoogleServices = "4.4.3"
    alias(libs.plugins.google.firebase.crashlytics) apply false   //googleFirebaseCrashlytics = "3.0.4"

app/build.gradle.kts

    implementation(platform("com.google.firebase:firebase-bom:33.16.0"))
    implementation("com.google.firebase:firebase-crashlytics-ndk")
    implementation("com.google.firebase:firebase-analytics")

By any chance, can you share an MCVE to help us investigate the issue? Thanks!

Hey @jiayuliang1314, per our engineers, This is a known issue in the Android Gradle plugin, see https://issuetracker.google.com/328687152. It affects Java-only apps using AGP version 8.3.2 and under.

To avoid the issue, either:

1. Upgrade Android Gradle plugin to 8.4.0+
   Follow the guide at https://developer.android.com/build/agp-upgrade-assistant

2. Or, add the Kotlin plugin to your app
   Follow the guide at https://developer.android.com/kotlin/add-kotlin

3. Or, do a technical workaround
   Follow the technical workaround described in https://issuetracker.google.com/issues/328687152#comment3

That said, I'll be closing this issue now. Let us know if the issue persists or if there's any misunderstanding so we can re-open the issue. Thanks!
