android.app.RemoteServiceException: Bad notification for startForeground: java.util.ConcurrentModificationException

I've been receiving this crash report for quite some time. It seems that this only happens on Android 8.0.0.
@Synchronized
override fun toForeground(id: Int) {
fun action() {
startForeground(id, builder?.build())
}
if (Looper.myLooper() === Looper.getMainLooper()) {
action()
} else {
Handler(Looper.getMainLooper()).post { action() }
}
}
Every channel has set up and the app can be run on Android 8.0.0 and later devices without any problem during testing except I cannot reproduce the crash.
I'm wondering why this crash happens and how to fix it.
Thanks in advance.

I also face this crash on Android 8.0.0 devices randomly.
Looking into AOSP source code it seems to result from this line: http://androidxref.com/8.0.0_r4/xref/frameworks/base/services/core/java/com/android/server/am/ServiceRecord.java#540:
public void postNotification() {
...
} catch (RuntimeException e) {
Slog.w(TAG, "Error showing notification for service", e);
// If it gave us a garbage notification, it doesn't
// get to be foreground.
ams.setServiceForeground(name, ServiceRecord.this,
0, null, 0);
ams.crashApplication(appUid, appPid, localPackageName, -1,
"Bad notification for startForeground: " + e);
}
Not sure what line exactly in the try block above this catch block causes it, but I assume a bug in AOSP itself. It operates with the notification asynchronously. So the chance that the app updates its notification while AOSP also operates on it, is quite high.
