Android HttpClient出现org.apache.http.conn.ConnectTimeoutException，导致下载不成功如何解决
在Android 4.0环境下，应用使用HttpClient向服务请求xml数据或者请求图片下载，出现下列异常(请求xml数据部分代码没有给出)

具体下载部分代码如下：
public int downFile(String fileName, String url, long curfilelength) {
InputStream input = null;
RandomAccessFile file = null;
int readSize = -1;
byte[] buffer = new byte[8024];
Log.d(TAG, "downFile url = " + url);
Log.d(TAG, "downFile fileName = " + url);
Log.d(TAG, "downFile curfilelength = " + curfilelength);
try {
if (curfilelength != 0) {
url = FilePath.GET_INTERRUPT_APK + "?url=" + url + "&fileSize="
+ curfilelength;
Log.d(TAG, "after change" + url);
}
HttpGet request = new HttpGet();
// request.addHeader("Range", "bytes=" + curfilelength + "-");
request.setURI(new URI(url));
HttpResponse response = client.execute(request);
file = new RandomAccessFile(fileName, "rw");
file.seek(curfilelength);
input = response.getEntity().getContent();
while ((readSize = input.read(buffer)) != -1) {
file.write(buffer, 0, readSize);
}
return DownLoadCallBack.DOWNLOAD_SUCCESS;
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
return DownLoadCallBack.DOWNLOAD_FAILD;
} finally {
if (input != null) {
try {
input.close();
input = null;
} catch (Exception e2) {
// TODO: handle exception
}
}
if (file != null) {
try {
file.close();
file = null;
} catch (Exception e2) {
// TODO: handle exception
}
}
}
}HttpClient也设置了超时情况：
//设置连接管理器的超时 ConnManagerParams.setTimeout(params, 1000); //设置连接超时 HttpConnectionParams.setConnectionTimeout(params, 5000); //设置socket超时 HttpConnectionParams.setSoTimeout(params, 10000);
请问，这个异常是一定会抛的吗，导致图片没有下载成功，我需要在处理异常的时候再次进行下载，还是代码哪有缺陷，需要改正。

把连接超时的时间调大些.比如设置成60000毫秒.

我不知道你怎么想的，要是有上万链接，岂不是很不效率了？
请问这个问题，您怎么解决的？我今天也遇到了。一开始访问是ok的，偶尔会出现这个异常。。。
问题解决了，在做耗时较长的http请求交互的时候，重新new一个httpClient对象，而不是用一个单例的httpclient对象进行管理，所有的http请求。
ConnManagerParams.setTimeout这个是连接最大等待时间，HttpConnectionParams.setConnectionTimeout这个是最大连接超时时间，HttpConnectionParams.setSoTimeout这个是读取超时时间，根据org.apache.http.conn.ConnectionPoolTimeoutException: Timeout waiting for connection，可以知道是在ConnManagerParams.setTimeout(params, 1000);这句抛出的，把1000改成10000吧。
sorry，多测试几次之后，还是出现了这个问题。
