这是我连接到URL的HTTP Get方法:
public void executeHttpGet() throws Exception {
try {
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet("http://test.mobibon.com.tw/MovieGoTest/GetMovies.js");
HttpResponse response = client.execute(request);
String retSrc = EntityUtils.toString(response.getEntity());
Log.i("bird",retSrc);
} finally {
}
}
以下是我的称呼方式:
try {
executeHttpGet();
} catch (Exception e) {
Log.i("bird","nothing");
e.printStackTrace();
}
http://test.mobibon.com.tw/MovieGoTest/GetMovies.js< -----此网址在我的浏览器中正常运行
但是Exception消息是:UnknownHostException
为什么?

您的AVD可能没有互联网连接。
关闭您的AVD并将其从CMD重新打开为E:\android-sdk-windows\tools>emulator -avd mj -dns-server 8.8.8.8

你好检查这个功能
private InputStream retriveInputStream(String url){
DefaultHttpClient client=new DefaultHttpClient();
HttpGet getRequest=new HttpGet(url);
try{
HttpResponse getResponse=client.execute(getRequest);
final int statusCode=getResponse.getStatusLine().getStatusCode();
if(statusCode!=HttpStatus.SC_OK){
Log.w(getClass().getSimpleName(),"Error " + statusCode + " for URL " + url);
}
HttpEntity getResponseEntity=getResponse.getEntity();
return getResponseEntity.getContent();
}catch(IOException ioe){
ioe.printStackTrace();
}
return null;
}
