Crashlytics reports the following problem, that is affecting a good percentage of the users of my application: Crashlytics报告了以下问题，该问题影响了我的应用程序的很大一部分用户：

I just added crosswalk as a plugin and I don't think I call any method explicitly (Cannot call this method before xwalk is ready). 我只是将crosswalk添加为插件，但我认为我没有明确调用任何方法（在xwalk准备就绪之前无法调用此方法）。 Any ideas? 有任何想法吗？ Thanks in advance! 提前致谢！

1 个解决方案

I think you're doing something to the XWalkView while it's still in the not-ready state. 我认为您在XWalkView仍处于未就绪状态时正在对其进行处理。

In the latest version of Crosswalk, there are some changes to the lib that the Crosswalk runtime isn't loaded yet when onCreate() is called. 在最新版本的Crosswalk中，对库的一些更改是在调用onCreate()时尚未加载Crosswalk运行时。 Therefore, if you want to initialize XWalkView or do something, wait until XWalkActivity.onXWalkReady() is called. 因此，如果要初始化XWalkView或执行某些操作，请等待直到XWalkActivity.onXWalkReady() 。

The solution is : 解决方案是：

Extend the activity containing XWalkView from XWalkActivity 从XWalkActivity扩展包含XWalkView的活动
Override XWalkActivity 's onXWalkReady() methods, and do necessary initialization stuff to the XWalkView there 重写XWalkActivity的onXWalkReady()方法，并在那里对XWalkView做必要的初始化工作
