Getting Started With Reteno SDK for Android

Install reteno_flutter_sdk using flutter pub command:

flutter pub add reteno_plugin

This will add entry in your project's pubspec.yaml (and run flutter pub get):

dependencies:
  reteno_plugin: (latest_version_here)

Add mavenCentral repository in your project level build.gradle:

buildscript { 
    repositories { 
    mavenCentral() 
    } 
... 
}

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"
}

Library	Description
com.reteno:fcm	FCM enables push notifications through SDK and all core functionality
firebase:firebase-messaging	Firebase cloud messaging
firebase:firebase-messaging-ktx	Firebase cloud messaging Kotlin extensions

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
    }
}

📘
Note
If you are using minSdkVersion<26 please add desugaring dependency in you app level build.gradle as follows

compileOptions {
    coreLibraryDesugaringEnabled true
    ...
}
...
dependencies {
    coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs:1.2.2'
    ...
}

Step 3: Edit Your MainApplication Class and Provider API Access-Key at SDK Initialization.

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

package [com.YOUR_PACKAGE];
import com.reteno.core.Reteno
import com.reteno.core.RetenoApplication
import com.reteno.core.RetenoImpl
import io.flutter.app.FlutterApplication

class CustomApplication : FlutterApplication(), RetenoApplication {
    private lateinit var retenoInstance: Reteno
    
    override fun onCreate() {
        super.onCreate()
        retenoInstance = RetenoImpl(this, "your_access_key_here")
    }
    
    override fun getRetenoInstance(): Reteno {
        return retenoInstance
    }
}

Step 3 Alternative: Use Lazy Initialization of Reteno

package [com.YOUR_PACKAGE];
import com.reteno.core.Reteno
import com.reteno.core.RetenoApplication
import com.reteno.core.RetenoImpl
import io.flutter.app.FlutterApplication

class CustomApplication : FlutterApplication(), RetenoApplication {
    private lateinit var retenoInstance: Reteno

    override fun onCreate() {
        super.onCreate()
        retenoInstance = RetenoImpl(this)
    }

    override fun getRetenoInstance(): Reteno {
        return retenoInstance
    }
}

and then in Flutter app, call Reteno.initWith

 await Reteno.initWith(
    accessKey: 'access_key',
    // optional
    isPausedInAppMessages: true,
    // optional
    lifecycleTrackingOptions: LifecycleTrackingOptions(
        appLifecycleEnabled: true,
        pushSubscriptionEnabled: true,
        sessionEventsEnabled: true,
    ),
    // optional if you want to use custom device id
    customDeviceId: () async {
        return await Amplitude.getInstance().getDeviceId();
    },
);

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.

Copy your FCM Server Key. In the Firebase console, click the gear icon next to Project Overview, then click Project Settings → Cloud Messaging → Manage Service Accounts. Go to Service accounts to download FirebaseAdminSdk account's json key.

Follow this manual to set up eSputnik admin panel with your Firebase key.

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.

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