在我的Android应用程序中，我调用一个php脚本，输出xml以在应用程序中使用。从分析中我发现，由于以下错误，某些用户无法获取数据：
libcore.io.ErrnoException: recvfrom failed: ETIMEDOUT (Connection timed out)
java.net.ConnectException: failed to connect to /81.19.145.162 (port 80): connect failed: EHOSTUNREACH (No route to host)
libcore.io.ErrnoException: recvfrom failed: ECONNRESET (Connection reset by peer)
libcore.io.GaiException: getaddrinfo failed: EAI_NODATA (No address associated with hostname)
java.net.ConnectException: failed to connect to /81.19.145.162 (port 80): connect failed: ECONNREFUSED (Connection refused)
异步任务的代码如下所示：
try {
HttpClient httpclient = new DefaultHttpClient();
fullUrl = new StringBuilder(url);
fullUrl.append("&lat=" + String.valueOf(lat) + "&lng=" + String.valueOf(lng) + "&token=" + token + "&types=" + types + "&limit=" + limit);
HttpPost httppost = new HttpPost(fullUrl.toString());
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
InputStreamReader reader = new InputStreamReader(is);
XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
factory.setNamespaceAware(true);
XmlPullParser xpp = factory.newPullParser();
xpp.setInput(reader);
int eventType = xpp.getEventType();
while (eventType != XmlPullParser.END_DOCUMENT) {
if (eventType == XmlPullParser.START_TAG) {
if (xpp.getName().equals("GeocacheTypeId")) {
typeSet.add(xpp.nextText().toString());
} else if (xpp.getName().equals("Code")) {
gcSet.add(xpp.nextText().toString());
} else if (xpp.getName().equals("Name")) {
nameSet.add(xpp.nextText().toString());
} else if (xpp.getName().equals("Latitude")) {
latSet.add(xpp.nextText().toString());
} else if (xpp.getName().equals("Longitude")) {
lngSet.add(xpp.nextText().toString());
} else if (xpp.getName().equals("HasbeenFoundbyUser")) {
foundSet.add(xpp.nextText().toString());
}
}
eventType = xpp.next();
}
} catch (Exception e) {
showError(context.getResources().getString(R.string.xmlerror), false);
sendToAnalytics();
}
被叫网址如下所示：
http://mywebsite.at/folder/getcaches.php?getcaches&lat=37.9249409&lng=-92.5329998&token=%xxxx%2BVIMwAcVFvV0PCEQWCsb12I%3D&hidefounds=true&username=someuser&types=2%2C3%2C8%2C9%2C12%2C1304%2C3773%2C137%2C6%2C13%2C453%2C3653%2C3774%2C4738%2C4%2C1858%2C5%2C11%2C&limit=1
对我来说，一切都很完美，我无法重现错误。我认为不同国家的不同移动服务提供商存在问题。
我希望你能告诉我，我怎么能避免这些错误。

答案 0 :(得分：0)
libcore.io.ErrnoException：recvfrom失败：ETIMEDOUT（连接超时）
java.net.ConnectException：无法连接到/81.19.145.162（端口80）：连接失败：EHOSTUNREACH（无主机路由）
libcore.io.ErrnoException：recvfrom failed：ECONNRESET（由对等方重置连接）
libcore.io.GaiException：getaddrinfo failed：EAI_NODATA（没有与主机名关联的地址）
这些都是用户端的连接问题。除了告诉用户检查网络连接并再试一次之外，您无法做任何事情。
java.net.ConnectException：无法连接到/81.19.145.162（端口80）：连接失败：ECONNREFUSED（拒绝连接）
这意味着服务器可以访问，但端口中没有任何内容，即Web服务器已关闭。努力提高服务器的可靠性。对于最终用户，消息是存在临时问题，用户应稍后再试。
