## Handling Amazon Device Messaging Push Notifications

Amazon Device Messaging (ADM) is a service used to send push notifications to apps running on Amazon devices, such as Kindle Fire tablets. By integrating ADM with your app, you can use Amazon Pinpoint to send notifications to your app through the ADM mobile push channel.

**Prerequisites**

To send push notifications to your app using Amazon Pinpoint and ADM, you need the following:

1. Amazon Developer account.

1. Client ID and client secret from Amazon Device Messaging.

1. ADM registration ID (provided by the end device that contains the ADM platform).

**Integrating ADM with Your App**

If you are already familiar with ADM and have ADM credentials, you can follow the steps for [Integrating Your App with Amazon Device Messaging](https://developer.amazon.com/public/apis/engage/device-messaging/tech-docs/adm-integrating-your-app) in the Amazon Developer documentation. Otherwise, for an introduction to ADM, see [Understanding Amazon Device Messaging](https://developer.amazon.com/docs/adm/overview.html).

To integrate with Amazon Pinpoint, your subclass implementation of `com.amazon.device.messaging.ADMMessageHandlerBase` should include the following methods and perform the corresponding calls:

**`onRegistered`**

Called when the device is registered with the ADM service. Provides the ADM registration ID that is needed to register the device with Amazon Pinpoint. Include the following call as part of this method:

```java
pinpointManager.getNotificationClient().registerDeviceToken(registrationId)
```

**`onUnregistered`**

Called when the device is no longer registered with the ADM service.

**`onMessage`**

Called when the device receives a message notification from ADM. Include the following as part of this method:

```java
NotificationDetails details = NotificationDetailsBuilder.builder()
                                .intent(intent);
                                .intentAction(NotificationClient.ADM_INTENT_ACTION)
                                .build();

pinpointManager.getNotificationClient().handleCampaignPush(details)
```

**Testing ADM Push Notifications**

To test, you need an Amazon Pinpoint project, an ADM client ID, and an ADM client secret.

Before you begin, augment your app to display the device token after registration. The device token can be retrieved by calling:

```java
pinpointManager.getNotificationClient().getDeviceToken()
```

Complete the following steps using the Amplify CLI and Amazon Pinpoint console to test ADM push notifications

Register ADM as a channel with your Amazon Pinpoint project. Provide the ADM client ID and the ADM client secret.

Run the following command to navigate to the Amazon Pinpoint console.

```bash
amplify console analytics
```

* On the left pane, select `Settings` and `Push notifications`. 
* Click `Edit` and select `Show more push notification services` and click `Amazon Device Messaging`. 
* Enter the `Client ID` and the `Client Secret` and click `Save` at the right bottom of the page.

Now `ADM` is registered as a push notification service.

Install your app on a device that has ADM enabled, and capture the generated device token.

Send a direct message to the device specifying the device token as the address.

* On the Amazon Pinpoint console, go to `Test messaging`. 
* Select `Push notifications` as the channel. 
* Enter the endpoint ID or the device token in the `Destinations`. 
* Select `ADM` as the push notifications service. 
* Create a message and click `Send message` at the bottom right corner of the page to send a direct message.
