我在Pixel XL设备中使用最新的Android O beta版本.
这是我在xml中的webvIEw.
<WebVIEw androID:ID="@+ID/launch_anim" androID:layout_wIDth="match_parent" androID:layout_height="150dp" androID:layout_centerHorizontal="true" />这是我在Activity类中使用的方式
WebVIEw launch_anim = (WebVIEw)findVIEwByID(R.ID.launch_anim);launch_anim.loadUrl("file:///androID_asset/launch_anim_centered.HTML");这是我在资产目录中的launch_anim_centered.HTML文件
<HTML><head> <style>body { background-color: #FFFFFF;}</style></head><body><CENTER> <img SRC="launch_anim_1x.gif"></CENTER></body></HTML>launch_anim_1x.gif文件是一个包含正在旋转的图像的gif文件.
当我启动应用程序时,运行此活动没有问题.然后我做AndroID-For-Work注册.注册后,一旦启动应用程序,此活动就无法呈现,它会抛出这样的异常

编辑：新信息.因此,我禁用了webvIEw以查看发生了什么,但在尝试访问cookieManager.getInstance()时应用程序崩溃了.这是堆栈跟踪：

解决方法:
这是AndroID O中的一个错误：如果在其中一个配置文件中禁用了Chrome,则两个配置文件的WebVIEw都会中断,直到Play更新为止.
要在配置期间解决此问题并避免更新WebVIEw,您可以使用包含名称com.androID.Chrome的DevicePolicyManager.enableSystemApp()在工作资料中启用Chrome,然后阻止用户使用DevicePolicyManager.setUninstallBlocked()禁用它.
如果您希望阻止用户使用Chrome浏览器,则应使用DevicePolicyManager.setPackagesSuspended()而不是DevicePolicyManager.setApplicationHidden().
