Integration

A push notification is an out-of-app alert that appears on the user’s screen when an important update occurs. Push notifications are a valuable way to provide your users with time-sensitive and relevant content to re-engage them with your app.

ADM (Amazon Device Messaging) is not supported on non-Amazon devices. To test Kindle push, you must have a FireOS device. Check out our help article for additional best practices.

Braze sends push notifications to Amazon devices using Amazon Device Messaging (ADM).

Step 1: Enable ADM

  1. Create an account with the Amazon Apps & Games Developer Portal if you have not already done so.
  2. Obtain OAuth credentials (Client ID and Client Secret) and an ADM API key.
  3. Enable Automatic ADM Registration Enabled in the Unity Braze Configuration window.
    • Alternatively, you may add the following line to your res/values/braze.xml file to enable ADM registration:
1
  <bool name="com_braze_push_adm_messaging_registration_enabled">true</bool>

Step 2: Update AndroidManifest.xml

In your app’s AndroidManifest.xml, add Amazon’s namespace to the <>manifest</> tag:

1
  xmlns:amazon="http://schemas.amazon.com/apk/res/android"

Next, declare permissions required to support ADM by adding <>permission</> and <>uses-permission</> elements after the <>manifest</> element:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
  <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:amazon="http://schemas.amazon.com/apk/res/android"
    package="[YOUR PACKAGE NAME]"
    android:versionCode="1"
    android:versionName="1.0">

  <!-- This permission ensures that no other application can intercept your ADM messages. -->
  <permission
    android:name="[YOUR PACKAGE NAME].permission.RECEIVE_ADM_MESSAGE"
    android:protectionLevel="signature" />
  <uses-permission android:name="[YOUR PACKAGE NAME].permission.RECEIVE_ADM_MESSAGE" />

   <!-- This permission allows your app access to receive push notifications from ADM. -->
  <uses-permission android:name="com.amazon.device.messaging.permission.RECEIVE" />

  <!-- ADM uses WAKE_LOCK to keep the processor from sleeping when a message is received. -->
  <uses-permission android:name="android.permission.WAKE_LOCK" />
    ...
  </manifest>

Next, declare that your app uses the device’s ADM feature and that your app is designed to remain functional without ADM present on the device (android:required="false") by adding an amazon:enable-feature element to the manifest’s application element. It is safe to set android:required as "false" because Braze ADM code degrades gracefully when ADM is not present on the device:

1
2
3
4
5
6
7
8
  ...
  <application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme">

    <amazon:enable-feature android:name="com.amazon.device.messaging" android:required="false"/>
  ...

Lastly, add intent filters to handle REGISTRATION and RECEIVE intents from ADM within your Braze AndroidManifest.xml file. Immediately after amazon:enable-feature, add the following elements:

1
2
3
4
5
6
7
<receiver android:name="com.braze.push.BrazeAmazonDeviceMessagingReceiver" android:permission="com.amazon.device.messaging.permission.SEND">
  <intent-filter>
      <action android:name="com.amazon.device.messaging.intent.RECEIVE" />
      <action android:name="com.amazon.device.messaging.intent.REGISTRATION" />
      <category android:name="com.yourapp.packagename" />
  </intent-filter>
</receiver>

Step 3: Store your ADM API key

First, save your ADM API key to a file named api_key.txt and save it in your project’s [Assets/Plugins/Android/assets][54] folder. Next, obtain an ADM API Key for your app.

Amazon will not recognize your key if api_key.txt contains any white space characters, such as a trailing line break.

To enable Braze to automatically open your app and any deep links when a push notification is clicked, set com_braze_handle_push_deep_links_automatically to true in your braze.xml:

1
<bool name="com_braze_handle_push_deep_links_automatically">true</bool>

If you would like to custom handle deep links, you will need to create a push callback that listens for push received and opened intents from Braze. See Custom handling push receipts and opens in the Android push documentation for more information.

Step 5: Add Client Secret and Client ID to Braze dashboard

Lastly, you must add the Client Secret and Client ID you obtained in Step 1 to the Braze dashboard’s Manage Settings page.

Manual push registration

Braze does not recommend using manual registration, but if you need to handle ADM registration yourself, add the following in your braze.xml:

1
2
<!-- This will disable automatic registration for ADM via the Braze SDK-->
<bool name="com_braze_push_adm_messaging_registration_enabled">false</bool>

Next, use registerPushToken to pass your user’s ADM registration_id to Braze:

1
Braze.getInstance(context).registerPushToken(registration_id);

ADM extras

Users may send custom key-value pairs with a Kindle push message as extras for deep linking, tracking URLs, etc. Unlike in Android push, Kindle push users may not use Braze reserved keys as keys when defining extra key-value pairs.

Reserved Keys Include:

  • _ab
  • a
  • cid
  • p
  • s
  • t
  • ttl
  • uri

If a Kindle reserved key is detected, Braze returns Status Code 400: Kindle Push Reserved Key Used.
