Question

当我通过WebView加载网址时，我有时会收到大量这样的消息：

10-19 19:18:38.056: ERROR/Web Console(6524): 
Uncaught Error: Too much time spent in unload handler. at v8/DateExtension:1

这个错误是什么意思？

Answer 1

这似乎是在webkit中的DateExtension.cpp中定义的。如果JS钩子（插入到Date.getTime中，如果设置了enableSleepDetection（true））被调用超过1000次，则抛出C ++异常。

您可能希望获取Android源代码以进一步了解它。该文件没有文档。

我得到了同样的错误。经过一番调查，我已经解决了这个问题。也许这段代码可以帮到你：

        {
            webView = (WebView) view.findViewById(R.id.transcationwebview);
                progressdialog = ProgressDialog.show(mContext, "",
                        mContext.getString(R.string.please_wait));
                progressdialog.setCancelable(true);
                progressdialog.setOnCancelListener(new OnCancelListener() {

                    @Override
                    public void onCancel(DialogInterface dialog) {
                        webView.stopLoading();
                        // webView.clearView();

                    }
                });



                webView.setWebChromeClient(new MyChromeClient());
                webView.getSettings().setBuiltInZoomControls(true);
                webView.getSettings().setLayoutAlgorithm(
                        WebSettings.LayoutAlgorithm.NARROW_COLUMNS);
                webView.getSettings().setUseWideViewPort(true);
                webView.getSettings().setLoadWithOverviewMode(true);
                webView.setWebViewClient(new WebViewClient() {
                    @Override
                    public boolean shouldOverrideUrlLoading(WebView view, String url) {
                        // TODO Auto-generated method stub
                        // view.loadUrl(url);
                        return false;
                    }

                    @Override
                    public void onPageFinished(WebView view, String url) {
                        // TODO Auto-generated method stub
                        super.onPageFinished(view, url);
                        if (progressdialog != null && progressdialog.isShowing()) {
                            progressdialog.dismiss();
                        } 

                    }

                    @Override
                    public void onPageStarted(WebView view, String url, Bitmap favicon) {
                        // TODO Auto-generated method stub
                        super.onPageStarted(view, url, favicon);
                    }

                    @Override
                    public void onReceivedError(WebView view, int errorCode,
                            String description, String failingUrl) {
                        // TODO Auto-generated method stub



                    }
                });
                webView.getSettings().setLoadWithOverviewMode(true);
                webView.getSettings().setPluginState(PluginState.ON);
                webView.getSettings().setBuiltInZoomControls(true);
                webView.getSettings().setPluginsEnabled(true);
                webView.setKeepScreenOn(true);
                webView.getSettings().setDomStorageEnabled(true);
                webView.getSettings().setAppCacheEnabled(true);
                webView.getSettings().setJavaScriptEnabled(true);
                webView.loadUrl(url);
}
    public class MyChromeClient extends WebChromeClient {
            @Override
            public void onProgressChanged(WebView view, int newProgress) {
                try {

                    if (progressdialog.isShowing()) {
                        progressdialog.setMessage(getString(R.string.loading)
                                + newProgress + " %");

                    } else {
                        /*
                         * webView.stopLoading(); webView.clearView();
                         */
                    }
                } catch (Throwable e) {

                    e.printStackTrace();
                }
            }
