Platform Configuration

Before you can start sending messages to Android, you will have to at least set up an FCM project and obtain a Google Maps key for Google Play Services based devices. If you also support Huawei Mobile Services based devices, you will also need to setup a PushKit enabled project (including the Receipts service) for Huawei Mobile Services based devices. This is all done via the Firebase Developer Console and Google Developer Console (for Google Play Services based devices) and Huawei Developer Portal (for HMS based devices). Keep reading this document to know how to configure your push provider platform.

Creating a FCM Project

In 2016, Firebase Cloud Messaging replaced the GCM (Google's Cloud Messaging) and became Android's official push provider. To be able to send notifications you currently need to create a project in Firebase.

Start by signing in Firebase. In their developer page you will find a button like this one:

fcm new project button 2023

This will open a page like this one, where you should provide a name for your project:

fcm new project page 2023

Firebase will generate an ID for you project, but you can also customize it:

fcm project id 2023

Depending on the capabilities you want to add to your project, you might need to enable or disable some options.

After creating your project, you will automatically be redirected to the project area where you can find a button like this one:

fcm project settings 2023

In the project settings page you will find a tab for Cloud Messaging:

fcm project cloud messaging tab 2023

Service Account

For newly created apps, we recommend using the Firebase Cloud Messaging API. This API uses a Service Account which you can manage in the Google Cloud Console, by clicking in Manage Service Accounts:

fcm api manage service accounts 2023

In this page you will find a list of service accounts (Firebase should create one automatically, but you can always create new ones):

fcm service accounts list 2023

You should then click in the service account, and navigate to the Keys tab:

fcm service account keys tab 2023

Go ahead and click in Add Key, which should open a window as the one below:

fcm service account create key 2023

Select the JSON option and click Create. That should download a .json file to you computer.

You can then use that file and upload it to Notificare, in Settings > Services > FCM as the Service Account:

notificare fcm service account

Saving this change, will create an entry as follows:

notificare fcm service account ready 2023

After that, you are ready to start sending remote notifications to Android devices.

Server Key (legacy)

If instead you are using an existing app with the Cloud Messaging API (legacy), you will need to provide us a Server Key. However, we do recommend you to consider using the Firebase Cloud Messaging API, with a service account, because on June 20, 2024, Firebase will discontinue the Cloud Messaging legacy API.

You can however still use a Server Key in Notificare, simply copy it from the following section in Firebase, in Project Settings > Cloud Messaging:

fcm server key legacy 2023

And paste it in our dashboard in Settings > Services > FCM:

notificare fcm server key 2023

After saving these changes, you should be able to start sending remote notifications to Android devices.

Google Maps Key

Optionally if you want our library to handle Google Maps correctly you will need to enable access to this API in the Google's Developer console. This is only necessary if you intend to send notifications that use the map capabilities and if you are not already using yourself a Google Maps key in your app. If you do not want to use this functionality or you already use Google Maps in your app you can skip this configuration.

To enable this API and generate a API key, sign in into the Google's Developer Console and select the app you which to enable this API:

google console app selector

Then click in the Library menu item like shown below:

google console library

This will take you to a page where you find all the Google APIs. Locate and click in the Google Maps Android API link:

google console maps api

In this page you'll a short explanation about this API and the Enable button:

google console enable maps

Clicking in Enable will allow your project access to this API and show you a page that looks like this:

google console maps api enabled

Then you are ready to create an API key that can actually be used in your app. In the menu on the left, click in Credentials:

google console credentials

In this page expand the Create Credentials menu and click in API key:

google console credentials api key menu

This will generate a key and display it in a window like the one below:

google console api key generated

In production you might want to restrict the access of this key to your app but we will not cover this setup in this document.

Once you have generated an API key for Google Maps, go ahead an add an entry in your app's AndroidManifest.xml as follows:

    android:value="ADD_THE_KEY_HERE" />

Creating an HMS Project

HMS PushKit is Huawei's official push provider. To be able to send notifications you need to create a project in the HMS AppGallery.

Start by signing in to HMS AppGallery. In the AppGallery overview page you will find a button like this one:

hms my projects button

And add a new project

hms add project button

This will open a window where you will have to provide the name of your project:

hms new project window

After that, fill in the package name and language of the project you are creating:

hms create project window

Now, add an app to your project. You can add several apps per project.

hms add app button

In the app information window, you will find the necessary info to configure your app in Notificare.

hms app information window

For your app to run on both a production as well as a debug environment, it is important that you add SHA-256 fingerprints for any debug environment you will be running the app from.

Debug fingerprints can be found in your machine's local debug keystore

/> keytool -list -v -keystore ~/.android/debug.keystore

Enter keystore password:
Keystore type: jks
Keystore provider: SUN

Your keystore contains 1 entry

Alias name: androiddebugkey
Creation date: Oct 7, 2019
Entry type: PrivateKeyEntry
Certificate chain length: 1
Owner: C=US, O=Android, CN=Android Debug
Issuer: C=US, O=Android, CN=Android Debug
Serial number: 1
Valid from: Mon Oct 07 18:35:57 CEST 2019 until: Wed Sep 29 18:35:57 CEST 2049
Certificate fingerprints:
Signature algorithm name: SHA1withRSA
Subject Public Key Algorithm: 2048-bit RSA key
Version: 1

For production environments, you will need to use your own keystore that you use when signing your APKs.

Copy the App ID and App Secret and open our dashboard. Navigate to the app you've previously created and expand the Settings menu and click in Services:


Then you should click the Configure button in the HMS box:

hms service box

And paste the App ID and App Secret in the following field:

hms key

Finally you should click in the Save button to make sure you store these changes:

save button

After successful saving, you should now see the necessary settings to be filled in for allowing receipts to be received from HMS:

receipt config

In the side menu of the AppGallery Develop view, you can select PushKit, which will show you the status of PushKit.

hms service status window png

Enabling the Receipt service will allow us to receive information about message delivery, so we can inform you of app uninstalls, invalid tokens, etc.

Fill in the info from the Notificare's Dashboard as shown below:

hms receipt window

Click Test Receipt. After successful testing, click Submit and your setup is done.

You have now all the necessary platform configurations to start implementing our library. Keep reading our Implementation guides located here.
