用例是当应用程序从最近的列表中被杀死时,我必须向服务器发送注销请求。我使用 onTaskRemoved 来处理该问题,但是在Android O 和 P 中,我收到通知栏,提示我要避免“应用程序正在运行”。这是我运行前台服务的方式:
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
channelId = "my_service_channel_id";
String channelName = "My Foreground Service";
NotificationChannel channel = new NotificationChannel(channelId, channelName, NotificationManager.IMPORTANCE_LOW);
channel.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
channel.setSound(null, null);
notificationManager.createNotificationChannel(channel);
NotificationCompat.Builder builder =
new NotificationCompat.Builder(this, channelId)
.setContentTitle("")
.setAutoCancel(true)
.setContentText("");
startForeground(NOTIFY_ID, builder.build());
//notificationManager.cancel(NOTIFY_ID); // It doesn't remove notification
//notificationManager.deleteNotificationChannel(channelId); // it causes crash
}
我已经尝试过 JobScheduler ,但是 onTaskRemoved 不会触发。任何帮助将不胜感激。
