heap corruption detected by dlmalloc

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 =  Environment.getExternalStorageDirectory().getAbsolutePath() + "/qinhan_inc/AndroidServer/" + onm.getNodeId() + ".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。
