Thank you for any help,
Rick
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");
}
