Firebase Crashlytics causing NoSuchMethodError for checkNotGoogleApiHandlerThread() in Flutter app

Question

My Flutter app is crashing on startup with NoSuchMethodError when Firebase tries to initialize. The method checkNotGoogleApiHandlerThread() is not found in the Preconditions class, causing a FATAL EXCEPTION that terminates the app.

Error Log:

E/AndroidRuntime(1062): FATAL EXCEPTION: Firebase Blocking Thread #1
E/AndroidRuntime(1062): Process: com.xawalla.app, PID: 1062
E/AndroidRuntime(1062): java.lang.NoSuchMethodError: No static method checkNotGoogleApiHandlerThread()V in class Lcom/google/android/gms/common/internal/Preconditions; or its super classes (declaration of 'com.google.android.gms.common.internal.Preconditions' appears in /data/app/~~bqQsV4kN6IF_8w66umxitQ==/com.xawalla.app-Qw5hjYN7VtKv3uCS0zR9OQ==/base.apk)

Configuration

android/app/build.gradle:

gradle
plugins {
 id "com.android.application"
 id "kotlin-android"
 id "dev.flutter.flutter-gradle-plugin"
 id 'com.google.gms.google-services'
}
dependencies {
 implementation 'androidx.multidex:multidex:2.0.1'
 implementation platform('com.google.firebase:firebase-bom:32.7.0')
 implementation 'com.google.firebase:firebase-analytics'
 implementation 'com.google.firebase:firebase-crashlytics'
 implementation 'com.google.firebase:firebase-auth'
}

android/build.gradle:

gradle
buildscript {
 ext.kotlin_version = '1.8.22'
 dependencies {
 classpath 'com.android.tools.build:gradle:7.3.0'
 classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
 classpath 'com.google.gms:google-services:4.4.0'
 }
}

The crash occurs during Firebase initialization

Specifically in Firebase Blocking Thread #1 and Firebase Blocking Thread #0.

The missing method belongs to play-services-tasks@@18.1.0

I've already tried to update Kotlin to 1.8.22; use Firebase BOM 32.7.0; force specific Play Services version, complete cleanup (flutter clean, gradle clean).

Environment:

• Flutter 3.19.+

• Android minSdkVersion 23

• Android x86_64 emulator

• Google Services 4.4.0

How to resolve this Google Play Services version conflict that's causing the NoSuchMethodError in Firebase Crashlytics without removing Crashlytics from the project?

Answer 1

This crash happens because one of your Firebase/Play-Services libraries is pulling in an old version of com.google.android.gms:play-services-basement, and that older version does not contain the method:

Preconditions.checkNotGoogleApiHandlerThread()

• Mirchen Maibaze: How can I identify which library is pulling the old version and which version should I force?
