React Native Android SDK Setup

Getting Started with Reteno SDK for Android

  1. Install reteno-react-native-sdk using yarn:
yarn add reteno-react-native-sdk

or npm

npm i reteno-react-native-sdk
  1. Add mavenCentral repository in your project level build.gradle:
buildscript { 
    repositories { 
    mavenCentral() 
    } 
... 
}
  1. Add reteno and firebase dependencies in application level build.gradle:
dependencies {
    implementation 'com.reteno:fcm:(latest_version_here)'
    ...
    implementation "com.google.firebase:firebase-messaging:23.1.0"
    implementation "com.google.firebase:firebase-messaging-ktx:23.1.0"
}

Setting up SDK

Follow our setup guide to integrate the Reteno SDK with your app.

Step 1: Enable androidx in your gradle.properties file

android.useAndroidX=true
android.enableJetifier=true

Step 2: Add com.reteno:fcm and firebase dependencies in build.gradle

📘

Note

Java 1.8 compiler is required. In app level build.gradle:

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

Step 3: Edit your MainApplication class and provider API Access-Key at SDK initialization.

📘

To setup SDK you need an SDK_ACCESS_KEY, visit Managing Mobile SDK Access Keys to get it.

Below is sample code you can add to your application class which gets you started with RetenoSDK.

package [com.YOUR_PACKAGE];

import android.app.Application;

import androidx.annotation.NonNull;

import android.content.Context;
import com.facebook.react.PackageList;
import com.facebook.react.ReactApplication;
import com.facebook.react.ReactInstanceManager;
import com.facebook.react.ReactNativeHost;
import com.facebook.react.ReactPackage;
import com.facebook.react.bridge.ReactContext;
import com.facebook.react.config.ReactFeatureFlags;
import com.facebook.soloader.SoLoader;
import com.reteno.sample.newarchitecture.MainApplicationReactNativeHost;
import java.lang.reflect.InvocationTargetException;
import java.util.List;

import com.reteno.core.Reteno;
import com.reteno.core.RetenoImpl;
import com.retenosdk.RetenoReactNativeApplication;

public class MainApplication extends Application implements ReactApplication, RetenoReactNativeApplication {

    private Reteno retenoInstance;

    @Override
    public void onCreate() {
        super.onCreate();
        retenoInstance = new RetenoImpl(this, "your_access_key_here");
    }

    @NonNull
    @Override
    public Reteno getRetenoInstance() {
        return retenoInstance;
    }

    @Override
    public ReactContext getReactContext() {
        return this.getReactNativeHost().getReactInstanceManager().getCurrentReactContext();
    };
}

Step 4: Set up your Firebase application for Firebase Cloud Messaging:

  • Download your google-services.json config file (see how here).

  • Add the above file to your root app/ folder.

Firebase
  • Copy your FCM Server Key. In the Firebase console, click the gear icon next to Overview.
FCM Server Key

Click Project Settings → Cloud Messaging → Manage Service Accounts.

Cloud Messaging

Go to Service accounts to download FirebaseAdminSdk account's json key.

FirebaseAdminSdk

Now you are ready to run your app and send a marketing push notification to your application.

Run your app on a physical Android device to make sure it builds correctly.

Step 5 (OPTIONAL): Using Firebase for Remote notifications

If you already use Firebase for Remote notifications and would like to use Reteno as well, you need to Create a custom Messaging Service Class:

In your project folder, create a new Java Class file. You can choose any name for it, we'll use CustomMessagingService.java for the convenience.
And put those contents in this Class. Basically, we override the MessagingService that is provided by firebase, by a custom one, that's extended from RetenoFirebaseMessagingService.

package com.reteno.sample; // <-- make sure to replace it with your package name

import androidx.annotation.NonNull;

import com.google.firebase.messaging.RemoteMessage;
import com.reteno.fcm.RetenoFirebaseMessagingService;

public class CustomMessagingService extends RetenoFirebaseMessagingService {
  @Override
  public void onCreate() {
    super.onCreate();
    // Your code here
  }

  @Override
  public void onNewToken(@NonNull String token) {
    super.onNewToken(token);
    // Your code here
  }

  @Override
  public void onMessageReceived(@NonNull RemoteMessage message) {
    super.onMessageReceived(message);
    // Your code here
  }
}

And one more change, you need to go to your AndroidManifest.xml usually located in .../android/app/src/main/AndroidManifest.xml and add the above service, so it will be used for Firebase messaging events in your application tag:

<service android:name=".CustomMessagingService" android:exported="false">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT"/>
    </intent-filter>
</service>

So your AndroidManifest.xml will look something like this: 

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.reteno.sample">

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

    <application
      android:name=".MainApplication"
      android:label="@string/app_name"
      android:icon="@mipmap/ic_launcher"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:allowBackup="false"
      android:networkSecurityConfig="@xml/network_security_config"
      android:usesCleartextTraffic="true"
      android:theme="@style/AppTheme">
      <service android:name=".CustomMessagingService" android:exported="false">
        <intent-filter>
          <action android:name="com.google.firebase.MESSAGING_EVENT"/>
        </intent-filter>
      </service>
      <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|screenSize|smallestScreenSize|uiMode"
        android:launchMode="singleTask"
        android:windowSoftInputMode="adjustPan"
        android:exported="true">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
      </activity>
    </application>
</manifest>

Note

Android Debug Mode enables you to ensure that all events and user properties are logged correctly.
