Push notifications are an essential feature in mobile app development that allows you to engage with your users even when they are not actively using your app. With push notifications, you can deliver important updates, reminders, and personalized messages directly to your users’ devices. In this tutorial, we will walk through the steps to create push notifications on Android Studio, making it easier for you to communicate with your app users effectively.
Step 1: Set up Firebase Cloud Messaging (FCM) in your project by creating a new Firebase project on the Firebase console website. Follow the instructions on the website to integrate FCM into your Android project. Obtain the google-services.json file and add it to your project’s app folder.
Step 2: Create a new class in your Android Studio project called `MyFirebaseMessagingService` that extends `FirebaseMessagingService`. Override the `onMessageReceived` method to handle incoming messages and customize the notifications according to your requirements. You can extract the message content and customize the title, message, and other notification properties.
Step 3: Register the `MyFirebaseMessagingService` class in your AndroidManifest.xml file by adding the following lines within the `` section:
Step 4: In your app’s main activity or launcher activity, register the FCM token by calling the `FirebaseMessaging.getInstance().getToken()` method. This token uniquely identifies the device and allows you to send push notifications to specific devices or topics.
Step 5: Test the push notification functionality by sending a test notification from the Firebase console website. Use the token received in the previous step to target a specific device or topic.
Step 6: Customize the notification appearance and behavior by creating a notification channel. To do this, create a new class called `NotificationHelper` and handle the channel creation and notification building logic. Set the channel ID, name, and other properties according to your app’s requirements.
Step 7: Trigger a push notification from your app by calling the `sendNotification()` method in the `MyFirebaseMessagingService` class. Customize the notification content and use the `NotificationHelper` class to build and display the notification.

What are the 3 types of notifications?
Notifications are an essential part of our everyday digital lives, keeping us informed about various events, updates, and interactions. In the realm of technology, three main types of notifications are commonly used:
1. Push Notifications: Push notifications are messages that are sent to a user’s device from a specific app or website. They are designed to prompt immediate attention and engagement. Push notifications serve various purposes, such as notifying users about new messages, updates, reminders, or promotional offers. The advantage of push notifications is that they can be received even when the user is not actively using the app or website, ensuring that important information reaches them in real-time.
2. In-App Notifications: In-app notifications are messages that appear within a specific application or website while the user is actively engaged with it. These notifications aim to provide relevant information or updates related to the app’s features, content, or actions. In-app notifications can include personalized recommendations, alerts about new features or updates, or reminders to complete certain tasks within the app. They are designed to enhance the user experience by offering timely and context-specific information.
3. System Notifications: System notifications are the alerts or messages that originate from the operating system itself. These notifications often appear at the top of the screen, regardless of the active app, to inform users about system-level events or actions. System notifications can include battery or connectivity status, software updates, security alerts, or other general system-level messages. They are critical for keeping users informed about important device-level information and ensuring smooth system functionality.
By understanding the different types of notifications available, developers and app designers can effectively utilize these notification systems to deliver timely, relevant, and engaging information to users, depending on their preferences and needs.
