我正在尝试启动前台服务如下:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel chan = new NotificationChannel(
getApplicationContext().getPackageName(),
"My Foreground Service",
NotificationManager.IMPORTANCE_LOW);
chan.setLightColor(Color.BLUE);
chan.setLockscreenVisibility(Notification.VISIBILITY_SECRET);
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
assert manager != null;
manager.createNotificationChannel(chan);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(
this, "MyChannelId");
Notification notification = notificationBuilder.setOngoing(true)
.setSmallIcon(R.mipmap.my_icon)
.setContentTitle("App is running on foreground")
.setPriority(NotificationManager.IMPORTANCE_LOW)
.setCategory(Notification.CATEGORY_SERVICE)
.setChannelId("MyChannelId")
.build();
startForeground(1, notification);
}
此解决方案适用于Android 8.0模拟器。但我在Android 8.1,9.0和10.0模拟器上收到以下错误。
android.app.RemoteServiceException: Bad notification for startForeground: java.lang.RuntimeException: invalid channel for service notification: Notification(channel=MyChannelId pri=2 contentView=null vibrate=null sound=null defaults=0x0 flags=0x42 color=0x00000000 category=service vis=PRIVATE)

PS:我尝试了非模拟器Android 9.0设备,没有得到这个错误.

发生问题的原因是您正在使用
ID
创建通道,但在其他ID
中发送通知:因此,我认为您只需将Channel ID更改为
MyChannelID
,如下所示:wswtfjt72#
