Question

安卓开发时在service中创建一个线程，在新线程中通过http访问网络时出现异常，请问如何能正常访问网络？

如果在主线程中访问网络正常，通过service的新线程访问时就异常，代码如下，异常发生在httpResponse = httpClient.execute(httpGet); 请高手给与解答，重分答谢！

public void run() {
// TODO Auto-generated method stub
String forecastUrl = "http://m.weather.com.cn/data/101070201.html";
//生成一个请求对象
HttpGet httpGet = new HttpGet(forecastUrl);

//生成一个Http客户端对象
HttpClient httpClient = new DefaultHttpClient();
//使用Http客户端发送请求对象
InputStream inputStream = null;
try {
httpResponse = httpClient.execute(httpGet);
httpEntity = httpResponse.getEntity();
inputStream = httpEntity.getContent(); BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
String result = "";
String line = "";
while((line = reader.readLine()) != null){
result = result + line;
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
原来是模拟器问题，已经解决
