react native with firebase phone auth validation failed

Question

I'm trying to make react native with firebase phone auth through react-native-firebase docs and I get this error

Error: This app is not authorized to use Firebase Authentication. Please verifythat the correct package name and SHA-1 are configured in the Firebase Console. [ App validation failed ]

I have already created debug.keystore

keytool -genkey -v -keystore debug.keystore -alias androiddebugkey -storepass android -keypass android -keyalg RSA -validity 14000

then I get the SHA1

keytool -list -alias androiddebugkey -keystore "C:\Users\adirz\.android\debug.keystore" -storepass android -keypass android

and paste into firebase console and download the google-services.json and add to my react native app. then into my code I wrote

    import React, { Component } from 'react';
import {
  View,
  Button,
  Text,
  TextInput,
  Image,
  ActivityIndicator,
  Platform,

import firebase from 'react-native-firebase'

// Example usage if handling here and not in optionalCompleteCb:
// const { verificationId, code } = phoneAuthSnapshot;
// const credential = firebase.auth.PhoneAuthProvider.credential(verificationId, code);

// Do something with your new credential, e.g.:
// firebase.auth().signInWithCredential(credential);
// firebase.auth().linkWithCredential(credential);
// etc ...

and I still get this error.

I generated sha1 then I copy in my project I checked in AndroidManifest.xml I have the same packagename.

Answer 1

I know that sometimes is a little bit annoying go to step by step again, but normally is the better way to find the error.

Don't know exactly the IDE that you are using, so I make this with android Studio, but you can copy to yours. Or import the Android project to do this in Android Studio

First go to your firebase console and check your package name

Now in Android Studio check if your package is really the same, inside AndroidManifest.xml

If is not the same, you should change in firebase, even launch a new project

Next step SHA-1

You can use exactly this code (don't need to change) keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

In Android Studio open the Terminal (View > Tool Windows > Terminal) and Copy/Paste

Copy the SHA-1 (suggest to save in some place)

Go to Firebase console settings (click on the gear)

Check the SHA-1

download the google-services.json again.

Put in the app folder (Delete the previous one) You can see this in android studio using the "project" view

And what work for this question (copy from the question owner in a answer above)

You need to generate SHA1 from android studio when you run the project!

• Run your project.
• Click on Gradle menu where it on right-hand side.
• Expand Gradle Tasks tree.
• Double click on android -> signingReport and you'll see the result

For Android studio 2.2 - result will be available under Run console but use highlighted toggle button.
