表面 - dequeueBuffer失败（未知错误2147483646） [英] Surface - dequeueBuffer failed (Unknown error 2147483646)

问题描述

我一直在挣扎了3天一个Android应用程序，使用一个的WebView 来加载自己的网站，其中包含数千张图片。 该应用程序开始很好，但滚动槽几百图像的WebView后冻结（不强行关闭）的 logcat的（检查在引擎收录）节目

I've been struggling for 3 days with an android app that uses a webview to load my website that contains thousands of images. The application start well but after scrolling trough a couple hundred images the webview freezes (it doesn't force-close) the logcat (check it on pastebin) shows

E/Surface dequeueBuffer failed (Unknown error 2147483646)

我已经试过什么：

What I've tried:

1. 在限制对每一项活动图像的数量，当用户观看100 图像，启动另一个活动。
2. 清除web视图缓存onCreation，在onPause，的onStop等... clearCache（真）;
3. 设置web视图缓存为false setAppCacheEnabled（假）;
4. 杀死活性的开幕活动B和反之亦然
在
5. 将 webView.setLayerType（）为NONE，软件和硬件
6. 声明机器人：largeHeap =真正的和 机器人：hardwareAccelerated =真正的在清单

7. 把web视图一个占位符内将其删除之前，结束（）;

1. Limit the number of images on every activity, when a user views 100 images, start another activity.
2. Clear the webview cache onCreation, onPause, onStop, etc... clearCache(true);
3. Set the webview cache to false setAppCacheEnabled(false);
4. Kill activity A after opening activity B and vice versa
5. Set the webView.setLayerType() to NONE, SOFTWARE and HARDWARE
6. Declare "android:largeHeap="true" and android:hardwareAccelerated="true" on the manifest.

7. Put the webview inside a placeholder a remove it before finish();

webViewPlaceholder.removeView（myWebView）;
myWebView.removeAllViews（）;
myWebView.destroy（）;

webViewPlaceholder.removeView(myWebView);
myWebView.removeAllViews();
myWebView.destroy();

看来，Android的保持的WebView 在内存中清除缓存没有任何影响。
当我关闭应用程序并重新打开它立即出现错误，如此看来，即使不关闭应用程序释放其占用的内存。
老实说，我不明白的方式来解决这个问题，我读过的答案相当数量的在SO上的WebView问题，但我还是没能解决问题。
我想AP preciate一个光在这里！

It seems that android keeps the webview in memory and cleaning the cache doesn't have any effect.
When I close the app and reopen it the error appears immediately, so it seems that not even closing the app releases the memory it uses.
I honestly don't see a way to fix this, I've read a fair amount of answers at SO to problems on webview but I still couldn't fix the problem.
I would appreciate a light here!

推荐答案

有关奇巧4.4.3或更高版本将硬件加速设置为false：

for KitKat 4.4.3 or later set the hardware acceleration to false:

webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
