Démarrer le Service de Notification

Créer un récepteur de radiodiffusion, de recevoir le message de notification, puis démarrez le service.

Pour moi, ce travail est grandement..
Je vais écrire l'ensemble de l'exemple..
vous pouvez modifier la réponse si vous en avez besoin

C'est pour la Notification de créer

public void createNotification2(String aMessage) {
final int NOTIFY_ID = 11;
String name = getString(R.string.app_name);
String id = getString(R.string.app_name); //The user-visible name of the channel.
String description = getString(R.string.app_name); //The user-visible description of the channel.
NotificationCompat.Builder builder;
if (notifManager == null) {
notifManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel mChannel = notifManager.getNotificationChannel(id);
if (mChannel == null) {
mChannel = new NotificationChannel(id, name, importance);
mChannel.setDescription(description);
mChannel.enableVibration(true);
mChannel.setLightColor(getColor(R.color.colorPrimaryDark));
mChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
notifManager.createNotificationChannel(mChannel);
}
} else {
}
Intent Off_broadcastIntent = new Intent(this, Database_Update.class);
Off_broadcastIntent.setAction("on");
Off_broadcastIntent.putExtra("toastMessage", "1");
PendingIntent Off_actionIntent = PendingIntent.getService(this, 0, Off_broadcastIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Intent on_broadcastIntent = new Intent(this, Database_Update.class);
on_broadcastIntent.setAction("off");
on_broadcastIntent.putExtra("toastMessage", "0");
PendingIntent on_actionIntent = PendingIntent.getService(this, 0, on_broadcastIntent, PendingIntent.FLAG_UPDATE_CURRENT);

Intent content_intent = new Intent(this, Status_Page.class);
content_intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, content_intent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, id)
.setSmallIcon(android.R.drawable.ic_popup_reminder)
.setContentTitle(name)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setContentIntent(pendingIntent)
.setAutoCancel(false)
.setVibrate(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400})
.addAction(R.drawable.block, "ON", Off_actionIntent)
.addAction(R.drawable.notification, "OFF", on_actionIntent)
.addAction(R.drawable.clear, "CLOSE", cancel_actionIntent);
Notification notification = mBuilder.build();
notification.flags = Notification.FLAG_NO_CLEAR|Notification.FLAG_ONGOING_EVENT;
notifManager.notify(11, notification);
}

Dans Android Menifest

<service android:name=".Database_Update"></service>

C'est la classe de service
