带有 SearchView 的应用程序在恢复时崩溃 [英] App with SearchView crashing on restore

问题描述

我正在使用 SearchView 开发应用程序.

I'm developing app with SearchView.

当我打开搜索视图，按主页"并在启用不保留活动"选项的情况下恢复应用程序时，它会因异常而崩溃:

When I open the search view, pressing "Home" and restoring application with "Don't keep activities" option enabled, it crashes with exception:
