Webview内存不足错误

Question

我正在尝试将html数据加载到大多数时间都可以工作的webview上，但偶尔会有很长的内容，当我尝试加载数据时会抛出内存不足异常。

这是logcat;

这就是我加载数据的方式：

 public void setHtml(long entryId, String contentText, String link) {
    if (PrefUtils.getBoolean(PrefUtils.DISPLAY_IMAGES, true) || !PrefUtils.getBoolean(PrefUtils.LITE_VERSION, false)) {
        contentText = HtmlUtils.replaceImageURLs(contentText, entryId);
        if (getSettings().getBlockNetworkImage()) {
            // setBlockNetwortImage(false) calls postSync, which takes time, so we clean up the html first and change the value afterwards
            loadData("", TEXT_HTML, Constants.UTF8);
            getSettings().setBlockNetworkImage(false);
        }
    } else {
        contentText = contentText.replaceAll(HTML_IMG_REGEX, "");
        getSettings().setBlockNetworkImage(true);
    }

    loadDataWithBaseURL("https://twitter.com/", generateHtmlContent(contentText, link), TEXT_HTML, Constants.UTF8, null);

private String generateHtmlContent(String contentText, String link) {
    String s[] = link.split("/");
    String identifier = s[s.length - 1];

    String comments = "<div id=\"disqus_thread\"></div>\n" +
            "\t<script type=\"text/javascript\">\n" +
            "\tvar disqus_shortname = 'mpashonews';\n" +
            "\n" +
            "\tvar disqus_identifier = '" + identifier + "';\n" +
            "\tvar disqus_title = 'Comments';\n" +
            "\t(function() {\n" +
            "\tvar dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true;\n" +
            "\tdsq.src = '//' + disqus_shortname + '.disqus.com/embed.js';\n" +
            "\t(document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq);\n" +
            "\t})();\n" +
            "\t</script>\n" +
            "\t<noscript>Please enable JavaScript to view the <a href=\"https://disqus.com/?ref_noscript\" rel=\"nofollow\">comments powered by Disqus.</a></noscript>";

    return CSS + BODY_START + contentText + "<br/>" + comments + BODY_END;
}

加载数据时处理大字符串的最佳方法是什么？
