This error message indicates that your application is unable to get a push token from Firebase Cloud Messaging (FCM). This is usually caused by an incorrect Firebase configuration in your Android project.
Here are the most common configuration issues to check:
1. Verify google-services.json
Ensure that the google-services.json file you downloaded from your Firebase project is placed in the correct directory:
- Directory:
your_project/android/app/ - Content: Make sure this file corresponds to the correct Firebase project and that the
package_nameinside the file matches your application's package name.
2. Apply the Google Services Gradle Plugin
The Google Services plugin needs to be correctly applied in your Gradle files. Modern Android projects may use either Groovy (.gradle) or Kotlin DSL (.gradle.kts) for their build scripts. Make sure you use the syntax that matches your project setup.
For Groovy (build.gradle files):
In your project-level
android/build.gradlefile, add thegoogle-servicesclasspath dependency:buildscript { dependencies { // ... other dependencies classpath 'com.google.gms:google-services:4.3.15' } }In your app-level
android/app/build.gradlefile, apply the plugin at the bottom of the file:apply plugin: 'com.android.application' // ... other plugins // Apply the Google services plugin apply plugin: 'com.google.gms.google-services'
For Kotlin DSL (build.gradle.kts files):
In your project-level
android/build.gradle.ktsfile, add the plugin to thepluginsblock:plugins { // ... other plugins id("com.google.gms.google-services") version "4.4.1" apply false }In your app-level
android/app/build.gradle.ktsfile, apply the plugin in itspluginsblock:plugins { // ... other plugins id("com.google.gms.google-services") }
After verifying these steps, clean and rebuild your project. This should resolve the token retrieval error.
