Getting Started

Requirements

The ReachFive SDK supports Android SDK from API Level 19 (Android version 4.4 KitKat).

To initialize the ReachFive client:

You need a Domain URL and Client ID.
You must whitelist all available domains where the ReachFive SDK will be used.

This is done in the Allowed Origins (CORS) field of your ReachFive console, in the Settings menu.

Installation

ReachFive SDKs are published to Maven Central as separate modules.

allprojects {
    repositories {
        mavenCentral() (1)
    }
}

1	Add `mavenCentral` as a repository location in your project’s top-level `build.gradle` file.

Below are installation instructions for each module.

SDK Core

Core contains all the main tools and interfaces, and the methods related to standard authentication with an identifier and a password.

Add the following line to your app/build.gradle, replacing x.y.z with the latest SDK version:

dependencies {
    implementation "co.reachfive.identity:sdk-core:x.y.z"
}

The following permissions are required to communicate with the ReachFive servers. Add them to the AndroidManifest.xml file.

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

SDK WebView

This module uses a WebView to authenticate users, it enables all providers that are supported by ReachFive.

Add the following line to your app/build.gradle, replacing x.y.z with the latest version:

dependencies {
  implementation "co.reachfive.identity:sdk-webview:x.y.z"
}

You need to add this activity into the AndroidManifest.xml file:

<activity
    android:name="com.reach5.identity.sdk.webview.ReachFiveLoginActivity"
    android:screenOrientation="portrait" />

For mobile contexts, you must whitelist reachfive://${clientId}/callback using your Reachfive identity client ID.

This URL scheme is the default callback URL and is used to request a token when implementing the SDK Webview.

Facebook native provider

This module uses the Facebook native SDK to provide a better user experience.

Add the following lines to your app/build.gradle, replacing x.y.z with the latest version:

dependencies {
    implementation "co.reachfive.identity:sdk-facebook:x.y.z"
    implementation "com.facebook.android:facebook-login:4.37.0"
}

Refer to the Meta Connect (Facebook Login) guide to create your Facebook application.

If you’re using the latest version of the Facebook API, please remove the user_gender scope from the ReachFive client configuration to prevent any issues.

Add the line below into your string.xml resource file with your Facebook application ID:

<resources>
    <string name="facebook_app_id">FACEBOOK_APPLICATION_ID</string>
</resources>

Then add these lines into the AndroidManifest.xml file:

<manifest>
    <meta-data
      android:name="com.facebook.sdk.ApplicationId"
      android:value="@string/facebook_app_id" />
    <activity
      android:name="com.facebook.FacebookActivity"
      android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
      android:label="@string/app_name" />
</manifest>

Configure Google native provider

This module uses the Google native SDK to provide a better user experience.

First, include Google’s Maven repository in your top-level build.gradle file:
```
allprojects {
    repositories {
        google()
    }
}
```

To enable the service, add the line below at the bottom of your app/build.gradle file so that no dependency collisions are introduced:

apply plugin: 'com.google.gms.google-services'

Add the following line to your app/build.gradle, replacing x.y.z with the latest version:
```
dependencies {
    implementation "co.reachfive.identity:sdk-google:x.y.z"
}
```
Use the Google Connect guide to create your Google application.
Create a new Firebase project.
Once the project is created, configure the release (keystore.jks) and production (Google Play) SHA1s in FireBase with the application’s package name as shown with the command below:
```
keytool -list -v -keystore [keystorePath] - alias [aliasName] -storepass [storePassword] -keypass [keyPassword]
```

More information about the keytool utility in the Authenticating Your Client guide.

The ANDROID AUTH2 CLIENTS are generated automatically in the Google Console API through Firebase.

Download the google-services.json file and put it at the root of your Android project. You can find more information in Add Firebase to your Android project and Adding the JSON File.

Initialization

Below are all the functions accessible via the Android SDK.

In all the code examples below, the ReachFive client is instantiated and stored in a variable named client.

import android.content.Intent
import android.os.Bundle
import android.util.Log
import android.view.Menu
import android.view.MenuItem
import android.widget.Toast
import androidx.appcompat.app.AppCompatActivity
import com.Reach5.identity.sdk.core.ReachFive
import com.Reach5.identity.sdk.core.SdkConfig
import com.Reach5.identity.sdk.core.models.AuthToken
import com.Reach5.identity.sdk.core.models.ProfileSignupRequest
import com.Reach5.identity.sdk.facebook.FacebookProvider
import com.Reach5.identity.sdk.google.GoogleProvider
import com.Reach5.identity.sdk.webview.WebViewProvider
import io.github.cdimascio.dotenv.dotenv
import kotlinx.android.synthetic.main.activity_main.*

class MainActivity : AppCompatActivity() {
    // The ReachFive client
    private lateinit var client: ReachFive

    val DOMAIN    = "Your ReachFive domain"
    val CLIENT_ID = "Your ReachFive client ID"
    val SCHEME    = "Your ReachFive scheme" (1)

    override fun onCreate(savedInstanceState: Bundle?) {

        // The configuration parameters needed by the ReachFive client
        val sdkConfig = SdkConfig(domain = DOMAIN, clientId = CLIENT_ID, scheme = SCHEME)

        // The list of the social providers needed by your application
        val providersCreators = listOf(GoogleProvider(), FacebookProvider(), WebViewProvider())

        client = ReachFive(
            sdkConfig = sdkConfig,
            providersCreators = providersCreators,
            // Your Android activity
            activity = this
        )

        // Initialize the ReachFive client
        client.initialize({ providers ->
            // On success, do something with the retrieved list of providers registered for this ReachFive client
            // ...
        }, {
            // On failure, log the error message returned by the ReachFive client
            Log.d("Reach5_MainActivity", "ReachFive init ${it.message}")
        })
    }
}

1	The `SCHEME` should follow the format: `reachfive://${clientId}/callback`. It is a URI for native apps.
