Android RemoteServiceException：从包发布的错误通知无法缓存 contentViews

我有一个 Android 应用程序由于未处理的异常而崩溃，但仅限于一台特定设备（运行 Nougat）。我相信他们是我的测试人员中唯一一位运行牛轧糖的人。这是例外：

Java.Lang.RuntimeException：从包 [我的 包名称]：无法缓存 contentViews：包=[我的包名称]

这是堆栈跟踪：

android.app.RemoteServiceException: Bad notification posted from package com.elephanigma.starmygrooves: Couldn't cache contentViews: package=com.elephanigma.starmygrooves

堆栈跟踪不显示我自己的任何代码。我的应用程序本身不会创建任何通知，但它确实使用了一个开源包（Xamarin Media Manager）来创建任何通知。堆栈跟踪也不显示该包的任何代码。

所以，我不知道该去哪里寻找。我尝试过搜索此异常，尽管我收到了几次“已发布错误通知”的点击，但它们似乎都没有解决我的问题。我没有收到任何“无法缓存 contentViews”的点击。

如果有帮助，这里是创建通知的包中的代码（据我所知）：（注意这是 C# 代码，因为它使用 Xamarin/Mono）

    /// <summary>
    /// When we start on the foreground we will present a notification to the user
    /// When they press the notification it will take them to the main page so they can control the music
    /// </summary>
    public void StartNotification(IMediaFile mediaFile, bool mediaIsPlaying, bool canBeRemoved)
    {
        var icon = (_appliactionContext.Resources?.GetIdentifier("xam_mediamanager_notify_ic", "drawable", _appliactionContext?.PackageName)).GetValueOrDefault(0);

        _notificationStyle.SetMediaSession(_sessionToken);
        _notificationStyle.SetCancelButtonIntent(_pendingCancelIntent);

        _builder = new NotificationCompat.Builder(_appliactionContext)
        {
            MStyle = _notificationStyle
        };
        _builder.SetSmallIcon(icon != 0 ? icon : _appliactionContext.ApplicationInfo.Icon);
        _builder.SetContentIntent(_pendingIntent);
        _builder.SetOngoing(mediaIsPlaying);
        _builder.SetVisibility(1);

        SetMetadata(mediaFile);
        AddActionButtons(mediaIsPlaying);
        if (_builder.MActions.Count >= 3)
            ((NotificationCompat.MediaStyle)(_builder.MStyle)).SetShowActionsInCompactView(0, 1, 2);

        NotificationManagerCompat.From(_appliactionContext)
            .Notify(MediaServiceBase.NotificationId, _builder.Build());
    }
