Snackbar问题(仅在调试模式下)

Question

我在android支持设计库中遇到了Snackbar的问题.奇怪的是,它只发生在我在调试模式下运行我的应用程序时,在发布模式下它完全可以正常工作.

有没有人对这个问题有所了解？它似乎是支持库中的一个错误.

码

using (var snackbar = Snackbar.Make(View, "Nieuwe order aangemaakt", Snackbar.LengthLong).SetAction("OK", v => { }))
    snackbar.Show();

例外

一个简单的清理/重建修复了这个问题.不敢相信这在几天前也行不通,当时我也试过了......
