当我使用Android键盘和Android O模拟器时,我遇到了这个问题.它总是给我错误的说法

"Android键盘(AOSP)已停止"

当我试图从Android键盘按下"？123"按钮,然后键盘自行关闭.

只有当我在Android Studio 3.0 Canary 7中使用带有API 26(Android O)的模拟器时才会出现此问题.请在下面粘贴错误消息.

在Android O中，我们可以使用具有不同优先级（重要性）的不同通知渠道。在我的代码中，我将频道重要性级别设置为“紧急”，即“在屏幕上发出声音并弹出”。

但是，当我转到通知设置时，关闭通道通知，然后再打开它，重要性级别将始终重置为中级（“无声音”），这是默认级别。

我知道我们总是可以手动更改重要性级别，但是有没有办法让它在关闭通道之前记住设置，以便当再次打开它时，它会自动恢复到以前的设置？
