问题描述
final notificationmanager manager = (notificationmanager) context.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationChannel chan = new NotificationChannel("MyNotificationChannel","Notification Title",notificationmanager.IMPORTANCE_HIGH);
chan.setSound(null,null);
manager.createNotificationChannel(chan);
final Notification notification =
(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O ? new Notification.Builder(context,"MyNotificationChannel") : new Notification.Builder(context))
.setContentTitle(context.getString(R.string.app_name))
.setContentText("Text")
.setSmallIcon(R.drawable.logo)
.setFullScreenIntent(PendingIntent.getActivity(context,myIntent,PendingIntent.FLAG_UPDATE_CURRENT),true)
.setCategory(Notification.CATEGORY_ALARM)
.setVisibility(Notification.VISIBILITY_PUBLIC)
.setongoing(true)
.build();
((Service) context).startForeground(12345678,notification);
当我尝试删除有关破坏活动的通知时,它适用于大多数设备,但适用于某些摩托罗拉设备或搭载 Android 10 的小米:
protected void onDestroy() {
try {
notificationmanager mnotificationmanager = (notificationmanager) getSystemService(Context.NOTIFICATION_SERVICE);
mnotificationmanager.cancel(12345678);
mnotificationmanager.deleteNotificationChannel("MyNotificationChannel");
}catch(Exception e){
e.printstacktrace();
}
}
这个异常通过了,通知没有删除,我尝试在线程中删除并进入另一个活动:
java.lang.SecurityException: Not allowed to delete channel "MyNotificationChannel" with a foreground service
