Ran*_*ndy 4 java android webview
我遇到了一个非常奇怪的崩溃webview.destroy();。但是，这不是典型的可堆栈跟踪错误。它似乎扼杀了我的应用程序。我现在无法访问logcat，但它在WebViewCoreThread中显示“致命信号11”错误，并且还显示有关分段错误的大日志。
在调用webview.destroy（）之前，我已经尝试了几乎所有方法。我的代码当前为：
parent.removeView(wv);
wv.stopLoading();
wv.clearAnimation();
wv.clearCache(true);
wv.clearHistory();
wv.clearSslPreferences();
wv.removeAllViews();
wv.freeMemory();
wv.destroyDrawingCache();
wv.clearFocus();
wv.destroy();
每次都崩溃。但是，当我替换wv.destroy();为Runnable并在5秒钟后运行Runnable时，它不会崩溃。我尝试过仅以10毫秒的延迟发布它，但是它有时可行，有时却没有。无论如何，使用延迟是一种hack，我不喜欢它，因为某些设备的速度更快或更慢，并且会以不同的方式运行。似乎在WebViewCoreThread的后台发生了一些事情，wv.destroy();需要在调用之前完成它。我还需要打电话给destroy，因为webview直到您做完才真正停止做事。
这是一个问题，主要是因为在活动可见时我需要销毁Webview并创建一个全新的Webview，并且在应用程序的生命周期中可能会发生多次。
这是日志转储：另外请注意，我知道它说“在连接时仍被调用”，但我已经分离了它。这真的让我感到困惑。

经过一整天的搜索和测试，我找到了答案。我的浏览器具有关闭浏览器时删除所有HTML5网络存储的设置。当我关闭该功能时，一切正常。因此，实际上webview.destroy();除了这样说外，与它无关：
为了删除所有HTML5网络存储，您必须致电WebStorage.getInstance().deleteAllData();。问题是此API调用存在未记录的问题（错误？）。进行此调用时，您必须具有Web视图的“活动”实例。如果您不这样做，则WebViewCoreThread将发送Fatal Signal 11信号，这将杀死您的应用程序。在我的应用程序中，在此WebStorage API函数之前，“ webview.destroy（）”被称为“ JUST”，这意味着进行调用时我没有“活动的” Webview。超时之所以起作用，是因为它将Webview保留了足够长的时间，以使WebStorage API调用具有可用的“活动” Webview。
我用3个按钮制作了一个超级简单的应用程序后发现了这一点：
如果您手动单击1、2、3，以便它始终以相同的致命信号11崩溃。但是，如果您单击1、3和THEN 2，则它总是可以工作。因此，我又做了两个按钮，只需单击一下即可完成这两个不同的顺序，它们显示出相同的结果。
长话短说：
删除所有数据之前，始终至少要有一个实时Web视图。因此，呼叫WebStorage.getInstance().deleteAllData();前webview.destroy();
