如何使用NotificationCompat.Builder和startForeground？ [英] How to use NotificationCompat.Builder and startForeground?

问题描述

短的问题：

我试图用NotificationCompat.Builder类，以创建将用于服务的通知，但由于某些原因，我不是没有看到通知，或者当无法取消服务应该被销毁（或从前景被停止）。

I'm trying to use the NotificationCompat.Builder class in order to create a notification that will be used for the service, but for some reason, i either don't see the notification, or can't cancel it when the service should be destroyed (or stopping from being in the foreground) .

我的code：

@Override
public int onStartCommand(final Intent intent, final int flags, final int startId) {
    final String action = intent == null ? null : intent.getAction();
    Log.d("APP", "service action:" + action);
    if (ACTION_ENABLE_STICKING.equals(action)) {
        final NotificationCompat.Builder builder = new Builder(this);
        builder.setSmallIcon(R.drawable.ic_launcher);
        builder.setContentTitle("content title");
        builder.setTicker("ticker");
        builder.setContentText("content text");
        final Intent notificationIntent = new Intent(this, FakeActivity.class);
        final PendingIntent pi = PendingIntent.getActivity(this, 0, notificationIntent, 0);
        builder.setContentIntent(pi);
        final Notification notification = builder.build();
        // notification.flags |= Notification.FLAG_FOREGROUND_SERVICE;
        // notification.flags |= Notification.FLAG_NO_CLEAR;
        // notification.flags |= Notification.FLAG_ONGOING_EVENT;

        startForeground(NOTIFICATION_ID, notification);
        // mNotificationManager.notify(NOTIFICATION_ID, notification);

    } else if (ACTION_DISABLE_STICKING.equals(action)) {
        stopForeground(true);
        stopSelf();
        // mNotificationManager.cancel(NOTIFICATION_ID);
    }
    return super.onStartCommand(intent, flags, startId);
}

注释的命令是我的考验，使其工作。没有工作的某些原因。

The commented commands are my trials to make it work. none worked for some reason.

我甚至增加了一个假的活动，因为它需要一个contentIntent，但它仍然无法正常工作。

I even added a fake activity since it wanted a contentIntent , but it still doesn't work.

任何人都可以请帮助？

推荐答案

我前一阵子有完全相同的问题，我发现，由于某些原因，通知ID 0不能很好地<$ C $工作C> startForeground（），它是 NOTIFICATION_ID ？

I had the exact same problem a while ago, and I found out that for some reason, the notification ID 0 doesn't work well with startForeground(), is it the value of NOTIFICATION_ID in your code?

编辑：文档现在已经更新声明，0是无效ID

the documentation has now been updated to state that 0 is an invalid ID
