"Error inflating RemoteViews" 在 Android 上托管一些小部件时 12
"Error inflating RemoteViews" when hosting some widgets on Android 12
我在 12 上尝试托管 一些小部件 （在本例中为 Gmail 小部件）时出错。我还有几个显示类似的小部件错误。
乍一看，问题似乎出在小部件的 xml 文件中，但一切都适用于以前的 Android 版本。 Android 12 主页启动器也会按预期加载小部件。
小部件托管在 Android 12 上有变化吗？
widgets making 有变化，但我没有发现托管有任何变化。
错误：

结果是 Android 12 错误。
它已在 Android 12L 中修复。
