Android的Web服務無法正常工作

Question

我試圖做一個程序，將GCM註冊ID發送學生註冊數據服務器。當我嘗試註冊用戶的父親名字和母親名字沒有姓氏 例子： 阿賈伊

和實施例

阿賈伊[空白]索德

在第一實施例中的名稱工作正常無需空白和姓..但第二示例名稱以空格一點兒也不作品..

即使我在名字和姓氏之間使用Underscore _，它也可以很好地工作。 我不知道怎麼回事錯

RegistrationApp.java

名字和喜歡_姓姓氏之間，

嘗試編碼通過使用下面的方法或編碼完整的網址值

String query = URLEncoder.encode("first name", "utf-8"); 
    String url = "http://stackoverflow.com/search?q=" + query; 

或

String encodedUrl = URLEncoder.encode(url, "UTF-8");
