public class AlarmReceiver extends BroadcastReceiver {


@Override

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationManager notificationManager = (NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);

        intent.putExtra("STARTED_BY_RECEIVER", true);

        PendingIntent pendingIntent = PendingIntent.getActivity(context, 100, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        String CHANNEL_ID = "channel id";// The id of the channel.
        CharSequence name = "Channel";
        int importance = NotificationManager.IMPORTANCE_HIGH;

        Notification notification = new Notification.Builder(context)
                .setContentIntent(pendingIntent)
                .setContentText("Some Text")

我已经制作了一个应用程序，它会按时显示用户在主要活动中选择的通知，并且只有当用户点击通知时通知才会消失，否则不会..除非我将手机更新为 android Oreo，否则它工作正常（ 8.0) 现在通知会在某个时间显示，但一段时间后会自动消失。如何让通知不会自动消失（在 android Oreo 中），但只有当用户点击它时才会消失？

好吧，我想通了。它是电池优化选项，它正在杀死我的应用程序，这就是为什么通知消失了。我从自动优化中删除了我的应用程序，现在它工作正常。
