AlarmManager is not triggered when App is closed

I have some in-App notification to show to users at a specific time but nothing is shown when the App is closed.

Setting alarm:

Intent alarmIntent = new Intent(mMotherActivity, ReminderAlarmManager.class);

if (ReminderNotificationType.CHANGE_LENS.equals(notificationType)) {
alarmIntent.putExtra("NOTIFICATION_TYPE", "REMINDER");
} else {
alarmIntent.putExtra("NOTIFICATION_TYPE", "ORDER");
}

long scTime = alarmDate.getTime();
PendingIntent pendingIntent = PendingIntent.getBroadcast(mMotherActivity, 0, alarmIntent, 0);
AlarmManager alarmManager = (AlarmManager) mMotherActivity.getSystemService(mMotherActivity.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, scTime, pendingIntent);


broadcast receiver:

public class ReminderAlarmManager extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {

String notificationType = intent.getStringExtra("NOTIFICATION_TYPE");
if(notificationType.equalsIgnoreCase("ORDER"))
{
Intent i = new Intent(context, OrderReminderNotificationService.class);
context.startService(i);
}
else if(notificationType.equalsIgnoreCase("REMINDER"))
{
Intent i = new Intent(context, ReminderNotificationService.class);
context.startService(i);
}
}
}


So when it comes to scTime, even if the App is closed, I would like to trigger a notification. So I'm calling a service by the PendingIntent, as follows:

public class OrderReminderNotificationService extends IntentService {

public OrderReminderNotificationService(String name) {
super(name);
}

@Override
protected void onHandleIntent(Intent intent) {

String ns = Context.NOTIFICATION_SERVICE;
NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);

Context context = getApplicationContext();
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
context);

Uri uri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
mBuilder.setContentTitle("Notification");
mBuilder.setContentText(context.getString(R.string.renewOrderNotificationMsg));
mBuilder.setSmallIcon(R.mipmap.ic_launcher);
mBuilder.setSound(uri);
mBuilder.setAutoCancel(true);

Intent notificationIntent = new Intent(this, LoginActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(2, mBuilder.build());
}


The part in the manifest concerning that:

<receiver android:name="com.company.utils.ReminderAlarmManager">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>


But nothing shows up... What am I doing wrong ?

Answer

Your AndroidManifest.xml should be like this:

<receiver android:name=".ReminderAlarmManager">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

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