问题描述
最近我注意到，当我加载的WebView基于关闭code从文件（使用的资产或本地目录），web视图会泄漏内存，一旦destroy（）方法被调用。我已经把范围缩小到一个引用的问题。该计划/ web视图，使原来的观点的副本，并失去了JNI表中的引用 - 这最终导致程序后，512项崩溃
I've recently noticed that when I load a webview based off code from a file (using assets or a local directory), the WebView will leak the memory once the destroy() method is called. I've narrowed it down to a referencing issue. The program/webview makes copies of the original view and loses the references in the JNI table - this eventually causes the program to crash after 512 entries.
我已经看到了这篇文章，但不渗漏的WebView修复似乎不使用HTML的资产或外部文件夹的工作。
I have seen this article, but the non-leaking webview fix does not seem to work with HTML in the assets or external folders.
应用完全基于服务器的时候这个问题不存在;但是，我需要的应用程序能够为同步数据，并更新脱机回购这些观点。
The issue does not exist when the application is entirely server based; but, I need the application to be able to "sync" data and update the offline repo with these views.
另外的信息：我已经采取了webviews，把他们在一个ViewPager允许滚动。在3.2.4 / 1不存在这个问题，但已经出现在4.0.3。我得到了很多JNI警告，（没能找到入口），他们仍然存在后的意见被破坏。我看着它通过HPROF，我已经注意到了，HTML下榻残留在失去了变数。
Further info: I have taken the webviews and put them in a ViewPager to allow for scrolling. This issue did not exist in 3.2.4/1 but has appeared in 4.0.3. I get a lot of JNI Warnings, (failed to find entry) and they still exist after the views are destroyed. I've looked at it through the hprof, and I have noticed that the HTML is staying residual in lost variables.
如何纠正这种行为将AP preciated任何光线。
Any light on how to correct this behavior would be appreciated.

更新：
要解决这个问题，必须从SD卡，或一些其他存储机构加载。该错误是永久性的，当加载JavaScript文件，我不知道它是否固定在Chrome浏览器，但它似乎并没有固定在浏览器的最新操作系统。
To fix this issue, you have to load from the SD Card, or some other storage mechanism. The bug is permanent when a Javascript file is loaded, I don't know if it's fixed in Chrome, but it does not seem to be fixed in Browser in the newest OS.
推荐答案
.destroy（） - >销毁此的WebView的内部状态。后这个web视图已经从该视图体系中除去此方法应被调用
.destroy() --> Destroys the internal state of this WebView. This method should be called after this WebView has been removed from the view system.
