【问题描述】：
问题： 尝试“连接”时，我遇到了间歇性但频繁的失败。 代码、调试消息和堆栈跟踪如下。我看过类似的 问题答案，和android开发人员帮助，但找不到 失败的答案。
感谢任何帮助。
代码：
public String doInBackground (String... urlArray) {
String string;
InputStream is = null;
int responseCode = 0;
Log.d("Data", "doInBackground ");
try {
URL url = new URL(urlArray[0]);
// Create a new HTTP URL connection
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
Log.d("Data", "connection= " + connection );
connection.setConnectTimeout(10000);
connection.setReadTimeout(10000);
connection.setDoInput(true);
connection.connect();
responseCode = connection.getResponseCode();
Log.d("Data", "responseCode= " + responseCode );
if (responseCode == HttpURLConnection.HTTP_OK) {
is = connection.getInputStream();
int len=50000;
string = readIt(is, len);
connection.disconnect();
is.close();
return string;
}
else {
connection.disconnect();
return "File Not Found";
}
}
catch (IOException e) {
Log.d("Data", "e.getCause()= " + e.getCause() );
Log.d("Data", "e.getMessage()= " + e.getMessage() );
e.printStackTrace();
return null;
}
}
