Thank you for any help,

EDIT I found my answer:

This was not a well documented answer. It appears in some of the newer versions of android, there is a bug with recycled url connections. To fix this (although there may be some performance issues), I needed to add:

if (Build.VERSION.SDK != null
&& Build.VERSION.SDK_INT > 13) {
urlConnect.setRequestProperty("Connection", "close");
}

Thanks!

Rick

看他们的分析是，这是Java的某些版本在回收httpconnection的一个Bug，通过添加如下判断，设置httpConnection的属性，可以解决这个问题：

if (Build.VERSION.SDK != null&& Build.VERSION.SDK_INT > 13) {urlConnect.setRequestProperty("Connection", "close");}
