Я создаю приложение-напоминание, но не могу разрешить метод setLatestEventInfo метода.

 public class NotifyService extends Service {

    public class ServiceBinder extends Binder {
        NotifyService getService() {
            return NotifyService.this;
        }
    }

    private static final int NOTIFICATION = 123;
    public static final String INTENT_NOTIFY = "com.example.seng.healthyapp.INTENT_NOTIFY";
    private NotificationManager mNM;

    @Override
    public void onCreate() {
        Log.i("NotifyService", "onCreate()");
        mNM = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.i("LocalService", "Received start id "   startId   ": "   intent);

        if (intent.getBooleanExtra(INTENT_NOTIFY, false))
            showNotification();

        return START_NOT_STICKY;
    }

    @Override
    public IBinder onBind(Intent intent) {
        return mBinder;
    }

    private final IBinder mBinder = new ServiceBinder();

    private void showNotification() {

        CharSequence title = "Alarm!!";
        int icon = R.drawable.ic_dialog_alert;

        CharSequence text = "Your notification time is upon us.";
        long time = System.currentTimeMillis();

        Notification notification = new Notification(icon, text, time);

        PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, SecondActivity.class), 0);

        notification.setLatestEventInfo(this, title, text, contentIntent);

        notification.flags |= Notification.FLAG_AUTO_CANCEL;

        mNM.notify(NOTIFICATION, notification);

        stopSelf();
    }
}

‘setLatestInfo` был удален в API 23: https://developer.android.com/sdk/api_diff/23/changes/android.app.Notification.html

Вместо этого вы должны использовать Notification.Builder : https://developer.android.com/reference/android/app/Notification .Builder.html

Здесь есть пример.

Я предполагаю, что вы используете устаревший учебник по Android. Попробуйте использовать те, из https://developer.android.com . Они самые надежные.
