Generate int unique id as android notification id

Generate int unique id as android notification id

In Android, you can generate unique IDs for notifications using various approaches. One common approach is to use a counter or timestamp-based method to ensure that each notification has a unique ID. Here's an example of how to generate unique notification IDs in Android:

import java.util.concurrent.atomic.AtomicInteger; public class NotificationIdGenerator { private static final AtomicInteger uniqueIdCounter = new AtomicInteger(0); public static int getUniqueId() { return uniqueIdCounter.incrementAndGet(); } }

In this example:

  1. We use an AtomicInteger to ensure that the ID generation is thread-safe.

  2. We initialize a static AtomicInteger called uniqueIdCounter with an initial value of 0.

  3. We create a static method getUniqueId() that increments the uniqueIdCounter and returns the new value. This method can be called whenever you need to generate a unique notification ID.

Here's how you can use this NotificationIdGenerator class to generate unique notification IDs when creating notifications in Android:

import android.app.Notification; import android.app.NotificationManager; import android.content.Context; import androidx.core.app.NotificationCompat; public class NotificationHelper { private static final String CHANNEL_ID = "your_channel_id"; // Replace with your channel ID public static void createNotification(Context context, String title, String message) { int notificationId = NotificationIdGenerator.getUniqueId(); NotificationCompat.Builder builder = new NotificationCompat.Builder(context, CHANNEL_ID) .setSmallIcon(R.drawable.ic_notification) .setContentTitle(title) .setContentText(message) .setPriority(NotificationCompat.PRIORITY_DEFAULT); NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); notificationManager.notify(notificationId, builder.build()); } }

In this example, we call NotificationIdGenerator.getUniqueId() to generate a unique notification ID for each notification created using the NotificationHelper. This ensures that each notification will have a distinct ID, which is necessary to manage and update notifications effectively in Android.
