推荐答案
这是不是一个错误本身的 Apache的HttpClient的/不可用（Java 1.4中）的是Apache的默认用户代理字符串的HttpClient
That is not an error itself, Apache-HttpClient/UNAVAILABLE (java 1.4) is the default User Agent string for your Apache HttpClient.
这发生在你不发送用户代理（用户代理）通过HTTP头，那么手机GBA服务警告你。
This happens when you don't send the User Agent ("User-Agent:") via HTTP headers, then the phone GBA Service warn you about that.
如果您想发送系统默认的用户代理，你可以做
If you want send the default system User Agent you can do
httpClient.getParams().setParameter(CoreProtocolPNames.USER_AGENT, System.getProperty("http.agent"));
这应该是像
Dalvik/1.6.0 (Linux; U; Android 4.2.2; Galaxy Nexus Build/JDQ39)
如果您要发送自定义用户代理，你可以做
or if you want sent a custom User Agent you can do
httpClient.getParams().setParameter(CoreProtocolPNames.USER_AGENT, "My user agent");
，也可以通过设置页眉的setHeader 法
requestOrPost.setHeader("User-Agent", USER_AGENT);
