Firebase Android Push Notification Support with RAD Studio 10.3.1

Firebase Android Push Notification Support with RAD Studio 10.3.1


Google has announced that the “The GCM server and client APIs are deprecated and will be removed as soon as May 29, 2019. Migrate GCM apps to Firebase Cloud Messaging (FCM), which inherits the reliable and scalable GCM infrastructure, plus many new features.”

In order to use push notification support in your FireMonkey Android applications going forward, you will need to use Google’s Firebase. In this blog post, we’re going to cover the steps required to add Firebase push notification support to your FireMonkey Android applications with Delphi, C++Builder and RAD Studio 10.3.1.

Before you get started, download the Firebase FMX package from the GetIt Package Manager in the IDE (Tools > GetIt Package Manager). You can find it in the “Tools” category.

As you can see in our latest product roadmap, we intend to simplify this support further in the upcoming 10.3.2 release (also adding support for Android Firebase push notifications in RAD Server) and provide fully integrated support for Firebase and additional related services in 10.4. Please note that features are not committed until completed and GA released.

To Firebase enable your application, there are 3 steps you need to follow:

Creating a Firebase project and registering your FireMonkey project in the Google Firebase console
Creating or updating an existing FireMonkey project in RAD Studio 10.3.1 using the built-in push notification component level support
Making modifications to your FireMonkey project to support Firebase instead of Google Cloud Messaging

Creating a Firebase project and registering your FireMonkey project in the Google Firebase console
Once you’ve downloaded the GetIt package and unzipped the files, follow the steps below.

1. Visit https://console.firebase.google.com/ and click on “+Add Project”, then enter a name for your project, i.e. FirebaseApp.



2. You will be asked to review and accept the Google terms before clicking “Create Project”.



3. After the project has been created, we need to register our FMX Android application.

From the left navigation pane, navigate to the gear icon and select ‘Project settings’.



4. Click on the Android icon to access the “Add Firebase to your Android app” page.



5. The default package name for a FireMonkey application is com.embarcadero.packagename. In this example, we’re changing it to com.embarcadero.FirebaseApp, but you should change this to com.yourcompany.packagename for your own applications.

Note: For existing applications that are available in the Google Play Store today, you will need to add the package name of that project here instead of assigning a new name. Click “Register app”.



6. Download the config file



Click ‘Next’ and skip this step at this point.

7. Convert the JSON settings file that we just download to the Android strings resource format file. Open the provided strings.xml file from the Firebase - FMX package downloaded through the GetIt Package Manager. This file contains all possible Firebase settings.

While you can update all entries in the template, only two parameters need to be filled in:

google_app_id and gcm_defaultSenderID.

You will find the required values in the google-services.json file which you downloaded in step 6.



Any unused parameters should be removed from the xml file at this point. Next a new node should be added in this file:

<string name="fcm_fallback_notification_channel_label" translatable="false">Notification channel for Firebase</string>



It specifies title for default notification channel. Save this strings.xml file to your FireMonkey application project folder, i.e. C:\MyFireBaseApplication

Creating or updating an existing FireMonkey project in RAD Studio 10.3.1 using the built-in push notification component level support
8. Create your new FireMonkey application by launching Delphi, C++Builder or RAD Studio 10.3.1 and selecting File > New > Multi-Device Application.

If you have an existing FireMonkey project that you want to update, open it at this point.

9. Change the FMX project name to match the project name registered in the Firebase console, i.e. FirebaseApp



Save your project files to the same directory as the updated strings.xml file from step 7, i.e. C:\MyFireBaseApplication

10. Add a TMemo control to your form for showing the Firebase event logs. Rename the memo control to MemoLog. Next, we need to initialize the Firebase push notification service and connection using an OnCreate event.





See the Snippets.txt file included in the GetIt package. The Snippets.txt file includes the code for creating the push notification service and connection, and for the event handlers described below. You can copy the code for creating the push notification service and connection from the snippet into your FireMonkey project.
