## Verified Google Signin for React Native on Android
This is a bare bones example of React Native Android using Gmail to
authenticate a user, and then verify the same user on a Node.js
backend server.
This example is a stripped down copy of https://github.com/invertase/react-native-firebase-authentication-example
Firebase React Native bindings are not used, but are left in place.
> ⚠️ [Please be sure your environment is set up correctly for React Native CLI.](https://reactnative.dev/docs/environment-setup)
-------------------------------
## Step A
Create C:/the-project/android/app/debug.keystore with keytool.exe
```bash
PS C:/the-project/android/app> keytool -genkeypair -v -storetype PKCS12 -keystore debug.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
Enter keystore password:yer-keystore-password
```
Put 'yer-keystore-password' into /keystore.REAL.properties twice
-------------------------------
## Step B
Get SHA1 and SHA256 values of keystore
```bash
PS C:/the-project/android/app> keytool -keystore debug.keystore -list -v
Enter keystore password:yer-keystore-password
Certificate fingerprints:
SHA1: 21:21:21:21:21:21:21:21:21:21:21:21:21:21:21:21:21:21:21:21
SHA256: a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7:a7
```
-------------------------------
## Step C
Put SHA1 and SHA256 into https://console.firebase.google.com/project/yer-project-name/settings/general/android:com.yer-project-name
Project | Your Apps | Android Apps | Add fingerprint
-------------------------------
## Step D
Get webClientId from your Firebase project's authentication provider.
Go to : https://console.firebase.google.com/project/yer-project-name/authentication/providers
Project | Authentication | Sign-in method | Provider - Google| Web SDK Configuration
Copy "703366983526-rqp153lgutts5rhlhit133tuv77p0pja.apps.googleusercontent.com"
Paste value into /src/config.json
-------------------------------
## Step E
Get google-services.json into /android/app/
Go to : https://console.firebase.google.com/project/yer-project-name/settings/general/android:com.yer-project-name
Project | Your Apps | Android Apps | google-services.json | DOWNLOAD file
-------------------------------
## Step F
Choose support email in yer-project-name
Go to : https://console.firebase.google.com/project/yer-project-name/settings/general/android:com.yer-project-name
-------------------------------
## Step G
Replace every 'fonecook3' instance in the project with yer-project-name.
I advise using only lowercase letters and numbers for your project name; no dashes either.
For example /src/app.json
"name": "fonecook3", ==> "name": "yer-project-name",
For example /android/app/build.gradle
applicationId "com.fonecook3" ==> applicationId "yer-project-name"
-------------------------------
## Step H
```bash
PS C:/the-project> yarn install
```
-------------------------------
## USB Run:
Bash 1
```bash
PS C:/the-project> yarn start
```
Bash 2
```bash
PS C:/the-project> adb devices
List of devices attached
52109e7dea7f2495 device
7dea7f249552109e device
adb -s 52109e7dea7f2495 reverse tcp:8081 tcp:8081
yarn android
```
## EMLUATOR Run:
Bash 1
```bash
PS C:/the-project> yarn start
```
Bash 2
```bash
PS C:/the-project> yarn android
```
Open in browser
http://localhost:8081/debugger-ui/
-------------------------------
## Release Build
```bash
PS C:/the-project/android> ./gradlew assembleRelease
```
Makes installable APKs that run without USB in [/android/app/build/outputs/apk/release/](/android/app/build/outputs/apk/release/)
The only permission used is Internet.
