public class Notifier extends BroadcastReceiver {
#SuppressWarnings("deprecation")
#Override
public void onReceive(Context context, Intent intent) {
SharedPreferences sPrefs = context.getSharedPreferences("loginData", 0);
String id = sPrefs.getString("id", "default value");
String userss = sPrefs.getString("user", "default value");
String pass = sPrefs.getString("pass", "default value");
if (id.trim().length() > 0) {
List<NotifierDetail> subjects = DataBase.notificationMethod(id);
if (subjects.size() > 0) {
User user = new User();
user.setUserName(userss);
user.setPassWord(pass);
User users = DataBase.login(user);
BaseConstants.user = users;
for (NotifierDetail sub : subjects) {
NotificationManager nm = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(
R.drawable.logo, " Notification Today",
System.currentTimeMillis());
notification.defaults=Notification.DEFAULT_SOUND;
notification.defaults=Notification.DEFAULT_VIBRATE;
DataBase.updateNotificationMethod(sub.getId());
notification.flags = Notification.FLAG_AUTO_CANCEL;
Intent in = new Intent(context, MainActivity.class);
PendingIntent pi = PendingIntent.getActivity(context, 0,
in, 0);
CharSequence name = "Notification";
CharSequence mess = name + " about " + sub.getSubject();
notification.setLatestEventInfo(context, name, mess, pi);
nm.notify(0, notification);
}
}
}
}
