Firebase Firestore GetInstance Failing on Android

Question

I am unable to obtain an instance of Firebase Firestore on Android.This line of code below fails repeatedly.

FirebaseFirestore db = FirebaseFirestore.getInstance();

It throws java.lang.IllegalArgumentException with the error

FirebaseOptions.getProjectId() cannot be null
Caused by: java.lang.IllegalArgumentException: FirebaseOptions.getProjectId() cannot be null
at com.google.firebase.firestore.FirebaseFirestore.zze(Unknown Source)
at com.google.firebase.firestore.FirebaseFirestore.getInstance(Unknown Source)

I have enabled Firestore on the console, I have used Firebase Assistant to ensure Android Studio project is synched up correctly with the console project. Other Firebase components that I am using such as Real-time Database, Authentication, Storage, etc works except Firestore.

I have added the dependency compile 'com.google.firebase:firebase-firestore:11.4.2'

What am I missing?

Answer 1

Copy project_id from google-services.json to string.xml then it works fine.

Answer 2

changing the project gradle google services worked for me thanks

just by adding in the project gradle, under dependencies

dependencies {

    classpath 'com.google.gms:google-services:4.2.0'

}

Answer 3

The project ID is read from the google-services.json file.

Make sure you have a recent google-services.json file and are using com.google.gms:google-services:3.1.0 or higher (not 3.0.0).

Answer 4

Try updating your implementation 'com.google.firebase:firebase-firestore:17.0.2'
That's that latest currently. Please check your firebase console for the most recent version
