4.4冻结与nativeOnDraw Android的网页视图失败;空地背景颜色 [英] Android Webview on 4.4 freezes with nativeOnDraw failed; clearing to background color

问题描述

我知道这个问题已经被问了许多<一个href=\"http://stackoverflow.com/questions/20675554/webview-rendering-issue-in-android-kitkat\">times并有arounds.But他们没有几个工作为我工作

我有一个使用的WebView一个应用程序。在打开许多应用程序，然后醒来这个应用程序有时会使web视图的空白。应用程序的其他组件协同工作，但WebView中被卡住。

我禁用了硬件加速的Andr​​oidManifest.xml 并没有奏效

 ＆lt;应用
    机器人：名字=com.nandish.app.MyApplication
    机器人：largeHeap =真
    机器人：hardwareAccelerated =假＆GT;
 

我试图在添加以下行至网页视图的构造函数

  setLayerType（View.LAYER_TYPE_SOFTWARE，NULL）;
 

即使这是行不通的。我能够始终如一地再现空白屏幕。结冰时，原木错误消息是

  09-11 23：29：31.237：W / AwContents（2976）：nativeOnDraw失败;结算到背景颜色。
 

解决方案

我的code的问题是，用在其他地方得到了编辑，因为它是一个静态变量web视图对象。我的坏，那是彻底的灾难使用这个对象作为静态的。有一次，我转换为实例变量，它的工作。

I know this question has been asked many times and there are few work arounds.But none of them work for me

I have a app that uses webview . On opening many apps and then waking up this app sometimes makes the webview blank. Other components of the app works but the webview is stuck.

I disabled the hardware acceleration in Androidmanifest.xml and it did not work

<application
    android:name="com.nandish.app.MyApplication"
    android:largeHeap="true"
    android:hardwareAccelerated="false">

I tried to add the following line in to the constructor of Webview

    setLayerType(View.LAYER_TYPE_SOFTWARE, null);

Even this does not work. I am able to reproduce the blank screen consistently. When it freezes, the error message on logs are

09-11 23:29:31.237: W/AwContents(2976): nativeOnDraw failed; clearing to background color.

解决方案

The problem with my code was the webView object that was used was getting edited in other place since it was a static variable. My Bad, that was complete disaster to use this object as static. Once I converted to instance variable, it worked.
