Android:HttpGet中的IllegalStateException

Question

我正在尝试GET使用HttpClient,但我一直在发送请求IllegalStateException.知道是什么导致了这个吗？我一直在寻找解决方案,但我没有"host=null"在日志中得到它意味着什么.如何设置主机,它与路径有何不同？这是我的logcat:

07-17 11:54:18.002: W/System.err(15422): java.lang.IllegalStateException: Target host must not be null, or set in parameters. scheme=null, host=null, path=google.com

和来源:

HttpClient getClient = new DefaultHttpClient();
HttpGet getData = new HttpGet(this.address);
try {
    HttpResponse gameResponse = getClient.execute(getData);
    return EntityUtils.toString(gameResponse.getEntity());
} catch (ClientProtocolException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
} catch (IllegalStateException e) {
    e.printStackTrace();
}

你必须添加http://到地址,以使其工作.如果你这样做,请避免使用URLEncoder.
