add collection to firestore with kotlin problems

Question

I am trying to understand and use firebasefirestore from android studio with kotlin.

I have been following tutorials from the official docs, and from udemy and youtube. I do the exact same thing as shown, but still my collection is not created in the firestore console.

I want to add a collection to firestore from within android studio with kotlin.

To my understanding all my code is correct, I have internet permission, I have all the dependencies needed in my gradle files.

And my code for adding a collection to firebase is the exact same as given in the official docs.

Still no matter what I do, I can not create a collection from running my app.

I can create a firestore collection from within the firestore console without a problem. My app runs and execute with out any errors (beside not creating the collection in firestore).

Here is my code

Manifest

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="eu.example.firestoretest">

    <uses-permission android:name="android.permission.INTERNET"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.FireStoreTest">
        <activity
            android:name=".MainActivity"
            android:exported="true"
            android:label="@string/app_name"
            android:theme="@style/Theme.FireStoreTest">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Creating a db

package eu.example.firestoretest

import android.util.Log
import androidx.compose.runtime.Composable
import com.google.firebase.firestore.ktx.firestore
import com.google.firebase.ktx.Firebase

@Composable
fun fireStoreTest(){

    // Create a FirebaseFirestore object
    val db = Firebase.firestore
    
    // Pass data onto the firestore db, it must be of type hashmap
    val user = hashMapOf(
        "first" to "Ada",
        "last" to "Lovelace",
        "born" to 1815
    )

    // add the user data to the collection
    db.collection("users")
        .add(user)
        .addOnSuccessListener {
            Log.d("FB", "onCreate: ${it.id}")
        }
        .addOnFailureListener {
            Log.d("FB", "onCreate: ${it}")
        }
}

I then call the function fireStoreTest in my main function, but it doesn't work.

Is there someone who could explain in very simple terms what it is I am doing wrong ?

Answer 1

I was also having similar issue where I was not able to add collection on Firestore from Android Studio. What worked for me is setting the rules of Firestore to this :

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if
          request.time < timestamp.date(2022, 5, 3);
    }
  }
}
