Delphi Firebase Cloud Messaging

Delphi programlama dili ile Firebase servisini kullanarak Push mesaj nasıl ayarlanır şimdi birlikte bakalım .


İlk olarak Firebase den hesap açalım sonra uygulamamızı oluşturalım.
Firebase consol dan uygulamamızı oluşturalım. Projemizi oluştururken uygulama ismini tam olarak yazalım etkileşim için önemli yoksa çalışmayacaktır. Örnek :com.embarcadero.FirebaseCloudMessaging gibi

Projemizi oluşturduktan sonra Radstudio id mizden project options -> Entitlement List menüsüne girelim ve Receive push notifications ayarını true yapalım.

procedure TfrmMain.ShowTokenExecute(Sender: TObject);
begin
  {$IFDEF ANDROID}
    PushService := TPushServiceManager.Instance.GetServiceByName(TPushService.TServiceNames.GCM);
    PushService.AppProps[TPushService.TAppPropNames.GCMAppID] := 'SENDER ID';
  {$ENDIF}
  ServiceConnection := TPushServiceConnection.Create(PushService);
  ServiceConnection.Active := True;
  ServiceConnection.OnChange := OnServiceConnectionChange;
  ServiceConnection.OnReceiveNotification := OnReceiveNotificationEvent;

  DeviceId := PushService.DeviceIDValue[TPushService.TDeviceIDNames.DeviceId];
  DeviceToken := PushService.DeviceTokenValue[TPushService.TDeviceTokenNames.DeviceToken];
  Memo1.Lines.Add('DeviceID: ' + DeviceId);
  Memo1.Lines.Add('FCM Token: ' + DeviceToken);
  Memo1.Lines.Add('Ready to receive!');
end;

procedure TfrmMain.OnServiceConnectionChange(Sender: TObject; PushChanges: TPushService.TChanges);
begin
  //Do something if the service connection changes
end;

procedure TfrmMain.OnReceiveNotificationEvent(Sender: TObject; const ServiceNotification: TPushServiceNotification);
begin
  //Do something with the notification received from FCM
end;

Sender id kısmızı Firebase -> Project Settings -> Cloud Messaging menüsünden ulaşıyoruz. Sender id kodlarımıza ekliyoruz.

Son olarak AndroidManifest.template.xml dosyamıza aşağıdaki satırı service tag larına ekliyoruz.

<service android:name="com.embarcadero.gcm.notifications.GCMIntentService" />

Bu işlemlerden sonra uygulamanızı derleyebilirsiniz. Firbase servisinden mesaj atıp uygulamanızda bildirim olarak göstere bilirsiniz
