Configuration

Obtaining secret and token to configure the library

First of all you must obtain an Account App Id and an Account Kit Client Token. To obtain them you must create a Facebook application using facebook developer's website.

In the part 1 of the following blog post series you will find detailed steps about how to create and configura a Facebook Account Kit application:

• Passwordless Authentication in React Native Using Facebook Account Kit (Part 1)
• Passwordless Authentication in React Native Using Facebook Account Kit (Part 2)
• Passwordless Authentication in React Native Using Facebook Account Kit (Part 3)

IOS Configuration

Add your Account App Id and an Account Kit Client Token to your project's Info.plist file

<plist version="1.0">
  <dict>
    ...
    <key>FacebookAppID</key>
    <string>{YOUR_FACEBOOK_APP_ID}</string>
    <key>AccountKitClientToken</key>
    <string>{YOUR_ACCOUNT_KIT_CLIENT_TOKEN}</string>
    <key>CFBundleURLTypes</key>
    <array>
      <dict>
        <key>CFBundleURLSchemes</key>
        <array>
          <string>ak{YOUR_FACEBOOK_APP_ID}</string>
        </array>
      </dict>
    </array>
    ...
  </dict>
</plist>

Android Configuration

Add your Account App Id and the Account Kit Client Token to the android/app/src/main/res/values/strings.xml:

...
<string name="fb_app_id">YOUR_FACEBOOK_APP_ID</string>
<string name="ak_client_token">YOUR_ACCOUNT_KIT_CLIENT_TOKEN</string>

Then update set your app metadata by editing the android/app/src/main/AndroidManifest.xml file:

...
<application>
    ...
    <meta-data
        android:name="com.facebook.sdk.ApplicationId"
        android:value="@string/fb_app_id" />
    <meta-data
        android:name="com.facebook.accountkit.ApplicationName"
        android:value="@string/app_name" />
    <meta-data
        android:name="com.facebook.accountkit.ClientToken"
        android:value="@string/ak_client_token" />
    ...
</application>
...

3. If you want AccountKit to prefill your phone number add the READ_PHONE_STATE permission to the android/app/src/main/AndroidManifest.xml file:

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

4. (Optional) Exclude backup for Access Tokens on Android >= 6.0

   As per this documentation, Account Kit does not support automated backup (introduced in Android 6.0). The following steps will exclude automated backup

   1. Create a file android/app/src/main/res/xml/backup_config.xml that contains the follwoing:

   <?xml version="1.0" encoding="utf-8"?>
   <full-backup-content>
     <exclude domain="sharedpref" path="com.facebook.accountkit.AccessTokenManager.SharedPreferences.xml"/>
   </full-backup-content>
   

   2. In your AndroidManifest.xml add the following to exclude backup of Account Kit's Access Token.

   <application
     //other configurations here
     android:fullBackupContent="@xml/backup_config" // add this line
   >
   

Usage

If you have issues with the method signatures you may be using an older version. Check the Releases Notes for breaking changes

import RNAccountKit from 'react-native-facebook-account-kit'

// Configures the SDK with some options
RNAccountKit.configure({
  responseType: 'token'|'code', // 'token' by default,
  titleType: 'login',
  initialAuthState: '',
  initialEmail: '[email protected]',
  initialPhoneCountryPrefix: '+1', // autodetected if none is provided
  initialPhoneNumber: '123-456-7890',
  facebookNotificationsEnabled: true|false, // true by default
  readPhoneStateEnabled: true|false, // true by default,
  countryWhitelist: ['AR'], // [] by default
  countryBlacklist: ['US'], // [] by default
  defaultCountry: 'AR',
  theme: {
    // for iOS only, see the Theme section
  },
  viewControllerMode: 'show'|'present', // for iOS only, 'present' by default
  getACallEnabled: true|false,
  setEnableInitialSmsButton: true|false, // true by default
})

// Shows the Facebook Account Kit view for login via SMS
RNAccountKit.loginWithPhone()
  .then((token) => {
    if (!token) {
      console.log('Login cancelled')
    } else {
      console.log(`Logged with phone. Token: ${token}`)
    }
  })

// Shows the Facebook Account Kit view for login via email
RNAccountKit.loginWithEmail()
  .then((token) => {
    if (!token) {
      console.log('Login cancelled')
    } else {
      console.log(`Logged with email. Token: ${token}`)
    }
  })

// Logouts the user, so getCurrentAccessToken() will retrieve null
RNAccountKit.logout()
  .then(() => {
    console.log('Logged out')
  })

// Retrieves the logged user access token, if any user is logged
RNAccountKit.getCurrentAccessToken()
  .then((token) => {
    console.log(`Current access token: ${token}`)
  })

// Retrieves the logged user account info, if any user is logged
RNAccountKit.getCurrentAccount()
  .then((account) => {
    console.log(`Current account: ${account}`)
  })

@MahbbRah put together a video tutorial of how to integrate the library you might find useful.

Examples

Try the examples. They are related to different React Native versions.

git clone https://github.com/underscopeio/react-native-facebook-account-kit
cd react-native-facebook-account-kit/examples/RN0XX
yarn
react-native run-ios
react-native run-android

Themes

iOS

import RNAccountKit, {
  Color,
  StatusBarStyle,
} from 'react-native-facebook-account-kit'

RNAccountKit.configure({
  ...,
  theme: {
    // Background
    backgroundColor: Color.rgba(0, 120, 0, 0.1),
    backgroundImage: 'background.png',
    // Button
    buttonBackgroundColor: Color.rgba(0, 153, 0, 1.0),
    buttonBorderColor: Color.rgba(0, 255, 0, 1),
    buttonTextColor: Color.rgba(0, 255, 0, 1),
    // Button disabled
    buttonDisabledBackgroundColor: Color.rgba(100, 153, 0, 0.5),
    buttonDisabledBorderColor: Color.rgba(100, 153, 0, 0.5),
    buttonDisabledTextColor: Color.rgba(100, 153, 0, 0.5),
    // Header
    headerBackgroundColor: Color.rgba(0, 153, 0, 1.0),
    headerButtonTextColor: Color.rgba(0, 153, 0, 0.5),
    headerTextColor: Color.rgba(0, 255, 0, 1),
    // Input
    inputBackgroundColor: Color.rgba(0, 255, 0, 1),
    inputBorderColor: Color.hex('#ccc'),
    inputTextColor: Color.hex('#0f0'),
    // Others
    iconColor: Color.rgba(0, 255, 0, 1),
    textColor: Color.hex('#0f0'),
    titleColor: Color.hex('#0f0'),
    // Header
    statusBarStyle: StatusBarStyle.LightContent, // or StatusBarStyle.Default
  }
})

To see the statusBarStyle reflected you must set the UIViewControllerBasedStatusBarAppearance property to true on your app's Info.plist file. You can do it from XCode

Android

Check this commit to see how it's done in our sample app

1. In your application styles.xml file (usually located in android/app/src/main/res/values folder) create a Theme with the following schema

<style name="LoginThemeYellow" parent="Theme.AccountKit">
    <item name="com_accountkit_primary_color">#f4bf56</item>
    <item name="com_accountkit_primary_text_color">@android:color/white</item>
    <item name="com_accountkit_secondary_text_color">#44566b</item>
    <item name="com_accountkit_status_bar_color">#ed9d00</item>

    <item name="com_accountkit_input_accent_color">?attr/com_accountkit_primary_color</item>
    <item name="com_accountkit_input_border_color">?attr/com_accountkit_primary_color</item>
</style>

See the full set of customizable fields here

2. In your app AndroidManifest.xml file (usually under android/app/src/main folder) set that Theme to the AccountKitActivity

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" <-- Add this line
    ...>

    <!-- Set the AccountKitActivity theme -->
    <activity
      tools:replace="android:theme"
      android:name="com.facebook.accountkit.ui.AccountKitActivity"
      android:theme="@style/LoginThemeYellow" />

</manifest>

Troubleshooting

Missing android.support.v4.content

error: package android.support.v4.content does not exist
import android.support.v4.content.ContextCompat;

This is because of the breaking change introduced in react-native 0.60.0 and therefore in our 2.0.0.

In order to fix the issue you should either upgrade to react-native 0.60.0 of use the 1.2.0 of this library

Issue: #196

I have problems running the example

If you have trouble running any example try the following:

1. Move the example out of the repo

2. Remove this package local dependency from package.json

   -    "react-native-facebook-account-kit": "file:../.."
   

3. Run yarn add react-native-facebook-account-kit

4. Re-run react-native run-android or react-native run-ios

A system issue occured, Please try again" when sending SMS

1. Check your FacebookAppID and AccountKitClientToken on iOS Info.plist and Android strings.xml are correct

2. If you have enabled the client access token flow in fb account kit dashboard, then responseType should be set to code when calling configure

// Configures the SDK with some options
RNAccountKit.configure({
    responseType: 'code'
    ...
})

Issue: #68

iOS only: Login screen doesn't show up

In some cases, if you implement the Login button in a presented Modal screen, you need to add viewControllerMode: 'show' into the configuration.

// Configures the SDK with some options
RNAccountKit.configure({
    viewControllerMode: 'show'
    ...
})

Issue: #167

I cannot integrate the library with RN versions < 0.40.0

Modify the android/build.gradle file to override the com.facebook.android:account-kit-sdk library with com.facebook.android:account-kit-sdk:4.15.0 and the compileSdkVersion and buildToolsVersion as depicted below

subprojects { subproject ->
    afterEvaluate{
        dependencies {
            compile ('com.facebook.android:account-kit-sdk:4.15.0'){
                force = true
                exclude group: 'com.parse.bolts', module: 'bolts-android';
                exclude group: 'com.parse.bolts', module: 'bolts-applinks';
                exclude group: 'com.parse.bolts', module: 'bolts-tasks';
            }
        }

        if(subproject.name == 'react-native-facebook-account-kit') {
            android {
                compileSdkVersion 23
                buildToolsVersion "23.0.3"
            }
        }
    }
}
