使用未在 Oreo 设备中检测到的信标进行通知

Question

我正在使用信标在检测到信标时显示通知。但是 Oreo 设备中没有显示任何通知。它适用于奥利奥版本以下的设备。我应该在通知部分或信标部分进行更改吗？

PS : 我已经知道 link 有答案了。我只是想确定更改是否必须单独在通知部分完成，或者信标也参与其中。

您必须在通知显示部分进行更改。

这里是我使用的代码示例

 private Notification createNotification(String msg, PendingIntent notificationPendingIntent) {

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        String CHANNEL_ID = "notification_chanel";// The id of the channel.
        CharSequence name = "App name";// The user-visible name of the channel.
        int importance = NotificationManager.IMPORTANCE_HIGH;

        NotificationChannel mChannel = new NotificationChannel(CHANNEL_ID, name, importance);
        Notification notification = new Notification.Builder(this)
                .setSmallIcon(R.drawable.logo_notext)
                .setContentTitle("Geofence Notification!")
                .setContentText(msg)
                .setAutoCancel(true)
                .setChannelId(CHANNEL_ID)
                .setContentIntent(notificationPendingIntent).build();

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

        mNotificationManager.createNotificationChannel(mChannel);

        return notification;

    } else {
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
        notificationBuilder
                .setSmallIcon(R.drawable.logo_notext)
                .setColor(Color.RED)
                .setContentTitle(msg)
                .setContentText("Geofence Notification!")
                .setContentIntent(notificationPendingIntent)
                .setDefaults(Notification.DEFAULT_LIGHTS | Notification.DEFAULT_VIBRATE | Notification.DEFAULT_SOUND)
                .setAutoCancel(true);
        return notificationBuilder.build();
    }
}
