在我可以帮助您之前，您的HTTP错误411状态中的InputStream是什么？

添加以下代码。

InputStream is = null;
if (httpURLCon.getResponseCode() != 200) {
    is = httpURLCon.getErrorStream();
} else {
    is = httpURLCon.getInputStream();
}

更新：您的Authorization标头值必须从不包含空格。该值必须为OAuth<space><comma-delimited-value-without-space>。

HTTP响应代码：411为URL：http：//api.twitter.com/oauth/request_token
