Android Push Handling

Customize Default Notification Channel

To customize default notification channel for new users use defaultNotificationChannelConfig builder parameter during sdk initialization

    Reteno.initWithConfig(
        RetenoConfig.Builder()
            .accessKey(...)
            .defaultNotificationChannelConfig { builder ->
                builder
                    .setName("Custom name")
                    .setDescription("Custom description")
                    .setImportance(NotificationManagerCompat.IMPORTANCE_HIGH)
                    .setLightColor(Color.RED)
                    .setLightsEnabled(true)
                    .setShowBadge(true)
                    .setVibrationEnabled(true)
                    .setVibrationPattern(longArrayOf())
                    .setSound(...)
            }
    .build()

    Reteno.initWithConfig(
        new RetenoConfig.Builder()
        .accessKey(...)
        .defaultNotificationChannelConfig((builder) -> {
            builder
                .setName("Custom name")
                .setDescription("Custom description")
                .setImportance(NotificationManagerCompat.IMPORTANCE_HIGH)
                .setLightColor(Color.RED)
                .setLightsEnabled(true)
                .setShowBadge(true)
                .setVibrationEnabled(true)
                .setVibrationPattern(longArrayOf())
                .setSound(...);
            return Unit.INSTANCE;
        }
        .build()

To customize channel parameters for existing users, use:

RetenoNotifications.updateDefaultNotificationChannel(
    name = "New name",
    description = "New description"
)

RetenoNotifications.updateDefaultNotificationChannel(
        "New name",
        "New description"
);

Deeplinks

How to Create Deep Links and Universal Links | Support

When the SDK receives a deeplink push notification, it creates an intent to open the application without triggering the web browser. This is not a default behavior, but it improves the user experience and allows skipping the app selection step after the URL resolution. If the application cannot handle the URL, the web browser opens the provided link.

For handling deeplinks on Android12+, keep in mind the recent changes as explained at developer.android.com

Also, make sure to set up the proper intent filter for your activity developer.android.com

Custom Data

You can pass your custom data in push notifications using the "Custom data" box at Yespo admin panel. You can handle this custom data payload in the Launcher activity or the activity that handles deeplinks in the onCreate or onNewIntent methods. Custom data is delivered via intent extras.

override fun onNewIntent(intent: Intent?) {
       super.onNewIntent(intent)
       val customDataValue = intent?.extras?.getString("customDataKey")
   }

@Override
   protected void onNewIntent(Intent intent) {
       super.onNewIntent(intent);
       String customDataValue = intent.getExtras().getString("customDataKey");
   }

📘

Note

If you send a push notification containing a link that your application cannot handle, the web browser will handle this link. In this case, the web browser handles the custom data payload. To retrieve custom data from such a push check the next section. You need a NotificationClicked broadcastReceiver then.

Images Carousel in Notification

In Reteno admin dashboard you may select up to 10 images to be sent with push notification. On Android platform the notification will be shown as a DecoratedCustomViewStyle. Images will be scaled to 500x250px in order to satisfy the Android OS limits. The carousel will flip images automatically with 2500ms interval.

Notification Events (push received, notification clicked)

If you wish to handle the notification click events, you can create a BroadcastReceiver component object and declare it in your AndroidManifest.xml file:

<!-- Add this Receiver to listen to PushReceived events -->
       <receiver
           android:name="com.example.CustomReceiverPushReceived"
           android:enabled="true"
           android:exported="true"/>
       <meta-data
           android:name="com.reteno.Receiver.PushReceived"
           android:value="com.example.CustomReceiverPushReceived" />

       <!-- Add this Receiver to listen to NotificationClicked events -->
       <receiver
           android:name="com.example.CustomReceiverNotificationClicked"
           android:enabled="true"
           android:exported="true"/>
       <meta-data
           android:name="com.reteno.Receiver.NotificationClicked"
           android:value="com.example.CustomReceiverNotificationClicked" />

Where com.example.CustomReceiverPushReceived and com.example.CustomReceiverNotificationClicked are your receivers.

It is important to add a tag containing the com.reteno.Receiver.PushReceived and com.reteno.Receiver.NotificationClicked names of your receivers so that the SDK will be able to trigger them.

Your receivers will receive a bundle containing the data payload that you send from the Yespo admin panel using the Custom data box.

override fun onReceive(context: Context?, intent: Intent?) {
       val customDataValue = intent?.extras?.getString("customDataKey");
   }

@Override
   public void onReceive(Context context, Intent intent) {
   String customDataValue = intent.getExtras().getString("customDataKey");
   }

The intent.getExtras() is the method, with the help of which we get the Bundle object. From the Bundle object, we get the string from the {"data":{"custom_data":"text for test"}} JSON payload by the data key.

📘

Note

The data key name is optional but recommended. You can use any other name.
We do not recommend using the notification key name to specify the name of the object in JSON and the es_interaction_id key name inside JSON.

Custom Pushes

As an app developer you may want to send not only Reteno-marketing push notifications to your user, but your own pushes. These may be push notifications related to your app-specific functionality, like chat, calendar events, incoming call notification, etc. In this case just create a custom Broadcast receiver and register it in the AndroidManifest.xml with the following intent-filter:

<receiver
        android:name="com.reteno.sample.CustomPushReceiver"
        android:enabled="true"
        android:exported="false" >
        <intent-filter>
            <action android:name="com.reteno.custom-push" />
        </intent-filter>
    </receiver>

Then just receive the notification's data payload in the Bundle under onReceive method of your BroadcastReceiver.

📘

Important

  1. Don't send custom push notifications with notification block in JSON body. Use data only. This will guarantee that the BroadcastReceiver receives your data payload consistently.

WRONG

{
  "to": "FCM_token",
  "notification":{
      "title":"Title_here",
      "body":"Body_here"
    }
}

RIGHT

{
  "to": "FCM_token",
  "data":{
      "Name" : "John",
      "Room" : 4,
      "Building" : 3
    }
}
  1. Don't send the following key in your data payload es_interaction_id.

WRONG

{
  "to": "FCM_token",
  "data":{
      "Name" : "John",
      "es_interaction_id" : 123
    }
}
