To implement push notifications in your Android online application, you'll need to use Firebase Cloud Messaging (FCM), a cross-platform messaging solution. Here's a breakdown of the process:

1. Set up a Firebase Project: If you don't already have one, create a Firebase project in the Firebase console (console.firebase.google.com). Add your Android app to this project. You'll need to download a google-services.json file and place it in your app's module-level app directory.

2. Add the FCM SDK: Include the necessary dependencies in your build.gradle (Module: app) file. This typically involves adding the firebase-messaging dependency.

3. Implement the Firebase Messaging Service: Create a service that extends FirebaseMessagingService. This service will handle receiving messages from FCM. Override methods like onMessageReceived to process incoming messages and display notifications. You'll typically use a notification builder to create the visual notification for the user.

4. Request Notification Permissions: Make sure to request necessary permissions at runtime, including notification permissions. You can do this using the NotificationManagerCompat class.

5. Send Notifications: Use the Firebase console or the FCM server APIs to send messages to your app. You can target specific devices or groups of devices using registration tokens. Registration tokens are unique identifiers for each instance of your app.

6. Handle Notification Clicks: Handle situations where the user taps on the notification. In your onMessageReceived method, you can include logic to open a specific activity or perform an action when a notification is selected.

7. Testing: Thoroughly test your implementation, making sure that notifications arrive correctly on different devices and under varying network conditions.

Here's a simple code snippet for the onMessageReceived method:

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    // ... Handle data payload and display notification using NotificationManagerCompat ...
}

Remember to consult the official Firebase documentation for the most up-to-date instructions and best practices. The process involves several steps and requires handling various aspects of notification delivery and user interaction. Proper error handling and security are crucial.

Firebase Cloud Messaging (FCM) is the industry-standard solution for Android push notifications.

Yeah, some of those apps work internationally. But be careful – not all countries are supported by every app. Try it out with a test message first!

While many temporary number apps advertise international SMS reception, their capabilities vary significantly. Some apps explicitly support specific countries, clearly listing them on their websites or within the app itself. Others may claim broader coverage, but this doesn't guarantee reliable reception from every country. Factors affecting international SMS reception include the app's infrastructure, the mobile carrier's policies in the target country, and the sending party's SMS gateway. Before relying on a temp number for SMS from a specific country, carefully check the app's documentation and consider testing it with a known sender in that country. In some cases, using a local SIM card or a different SMS receiving service specifically designed for international messaging might be more reliable.
