致命异常:android.app.RemoteServiceException Context.startForegro

Question

我们最近实现了前台服务，在安卓9(仅限三星设备(上，一些用户遇到了一些反复出现的崩溃，我们不知道是什么原因造成的。有人遇到过同样的问题吗？这个问题有解决办法吗？

Answer 1

我在使用安卓奥利奥或更高版本的三星和华为设备时遇到了同样的问题。我也会犯同样的错误。

如果我没记错的话，由于Android Oreo及以上版本，在使用startService()或startForegroundService()时需要使用startForeground()。

我通过将以下代码添加到服务类的onCreate函数中解决了这个问题。我创建了一个通知，并用startForeground()启动了它。

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationManager mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
NotificationChannel mNotificationChannel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_NONE);
mNotificationChannel.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
mNotificationManager.createNotificationChannel(mNotificationChannel);
Notification note = new NotificationCompat.Builder(this, CHANNEL_ID)
.setContentTitle("Reboot Sequence")
.setContentText("Rescheduling Alarms")
.setSmallIcon(R.drawable.ic_alarm_24dp)
.build();
startForeground(1, note);
}

我希望这对你有帮助。

即使使用startForeground((启动通知，也会发生这种情况。此问题是由某些设备上的软件错误引起的。因此，它无法在应用程序代码中解决。唯一现实的解决方案是在游戏开发者控制台上查看崩溃和ANR，并找到有问题的设备。然后转到同一开发人员控制台上的设备管理器并排除这些设备。我看到华为Y5导致了很多这样的崩溃。
