How to open an activity on notification click

I am using FCM to send custom notifications to the users, now i want that when an user clicks on the notification an activity should open.

Here is my code snippet from mainActivity.java:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel channel = new NotificationChannel("MyNotification", "MyNotification", NotificationManager.IMPORTANCE_DEFAULT);

            NotificationManager manager = getSystemService(NotificationManager.class);
            manager.createNotificationChannel(channel);
        }

And below is my Service class:

public class MyMessagingService extends FirebaseMessagingService {
@Override
    public void onMessageReceived(@NonNull RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);
        showNotification(remoteMessage.getNotification().getTitle(), remoteMessage.getNotification().getBody());
    }

    public void showNotification(String title, String message) {
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "MyNotification")
                .setContentTitle(title)
                .setSmallIcon(R.drawable.noti)
                .setAutoCancel(true)
                .setContentText(message);

        NotificationManagerCompat manager = NotificationManagerCompat.from(this);
        manager.notify(999, builder.build());
    }
}

Please tell me how to achieve this. Thanks in advance

For click notification and go a specific activity, you should use Pending Intent. like below:

Intent activityIntent = new Intent(getApplicationContext(), SpecificActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, activityIntent, PendingIntent.FLAG_UPDATE_CURRENT);

Then make your Notification Builder like this

NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "MyNotification")
                .setContentTitle(title)
                .setSmallIcon(R.drawable.noti)
                .setAutoCancel(true)
                .setContentIntent(pendingIntent)
                .setContentText(message);

So your finally showNotification() method looks like this:

public void showNotification(String title, String message, PendingIntent pendingIntent) {

    Intent activityIntent = new Intent(getApplicationContext(), SpecificActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, activityIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "MyNotification")
                .setContentTitle(title)
                .setSmallIcon(R.drawable.noti)
                .setAutoCancel(true)
                .setContentIntent(pendingIntent)
                .setContentText(message);

    NotificationManagerCompat manager = NotificationManagerCompat.from(this);
    manager.notify(999, builder.build());
}

           // Create an Intent for the activity you want to start
            Intent resultIntent = new Intent(this, ResultActivity.class);
            // Create the TaskStackBuilder and add the intent, which inflates the back stack
            TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
            stackBuilder.addNextIntentWithParentStack(resultIntent);
            // Get the PendingIntent containing the entire back stack
            PendingIntent resultPendingIntent =
                    stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);


            NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID);
            builder.setContentIntent(resultPendingIntent);

            NotificationManagerCompat notificationManager = 
            NotificationManagerCompat.from(this);
            notificationManager.notify(NOTIFICATION_ID, builder.build());

EDIT here is the code you want

public class MyMessagingService extends FirebaseMessagingService {
    @Override
    public void onMessageReceived(@NonNull RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);
        Intent activityIntent = new Intent(getApplicationContext(), YourActivity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, activityIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        showNotification(remoteMessage.getNotification().getTitle(), remoteMessage.getNotification().getBody(), pendingIntent);
    }

    public void showNotification(String title, String message, PendingIntent pendingIntent) {
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "MyNotification")
                .setContentTitle(title)
                .setSmallIcon(R.drawable.noti)
                .setAutoCancel(true)
                .setContentIntent(pendingIntent)
                .setContentText(message);

        NotificationManagerCompat manager = NotificationManagerCompat.from(this);
        manager.notify(999, builder.build());
    }
}
