必知的技术知识：heapcorruptiondetectedbydlmalloc

原生看书，下载完整版，解析所有html，抽取出所有编辑器，拿着内容去服务器获取图片路径，然后再通过路径去去下载文件，

现在走着走着，程序就直接崩掉了，报错日志如下：

报错就在最后两句，查了一下，其实就是thread开的过多，把heap整崩了而已

解决方案：

重新修改逻辑，将所有线程(Runnable)装到一个list中。开启一个线程池，里面最多装10个线程。同步下载，代码如图：

List onmList = DBManagerHelper.getInstance().getOnclassNode(common.tempUserId, common.tempCourseId);

if(onmList != null){

ExecutorService fixedThreadPool = Executors.newFixedThreadPool(10);

common.runnableList.clear();

Log.i("","parse所有Node开始时间：" + new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));

for (OnclassNodeModel onm : onmList) {

try {

String path = //代码效果参考：http://www.lyjsj.net.cn/wx/art_24129.html

HtmlParserFullVersion parser = new HtmlParserFullVersion();

//解析html，将编辑器和图表代码发送到服务器，获取生成的图片ftp地址

parser.parseHtml(path);

} catch (Exception e) {

e.printStackTrace();

}

}

Log.i("","parse所有Node结束时间：" + new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));

Log.i("","common.runnableList size is：" + common.runnableList.size());

for (Runnable runnable : common.runnableList) {

fixedThreadPool.execute(runnable);

}

}

解决，就是得排队。
