What is PendingIntent in Android SDK?

PendingIntent is a powerful feature in the Android SDK that allows an application to pass a runnable piece of data (an Intent) to another application (usually a system service) to be executed at a later time. It essentially acts as a wrapper around an Intent so that it can be fired by another application even if your application context is no longer available.

PendingIntents are commonly used for notifications, alarm services, and broadcast receivers. For example, when a user interacts with a notification, the PendingIntent allows your app to resume or perform a task without being open at that moment.

Example of PendingIntent:

// Create an Intent to launch your activity Intent intent = new Intent(context, YourActivity.class); // Create a PendingIntent to wrap the Intent PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); // Use the PendingIntent in a notification NotificationCompat.Builder builder = new NotificationCompat.Builder(context, CHANNEL_ID) .setSmallIcon(R.drawable.notification_icon) .setContentTitle("Title") .setContentText("Content text") .setPriority(NotificationCompat.PRIORITY_DEFAULT) .setContentIntent(pendingIntent) // Set the PendingIntent that will be triggered .setAutoCancel(true); NotificationManagerCompat notificationManager = NotificationManagerCompat.from(context); notificationManager.notify(NOTIFICATION_ID, builder.build());
