java - Android解析开户错误

Question

我正在尝试通过 parse.com 开设一个新帐户：

https://www.parse.com/docs/android_guide

但是，当我到达线路时：

user.setUsername("a");

然后它向我显示一个弹出窗口：“应用程序必须停止......”然后它退出

这是日志猫：

这是我的代码（我必须说服务器中不存在“a”用户名）

regbutton.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v) {
                ParseUser user = new ParseUser();
                user.setUsername("a");
                user.setPassword("a");
                user.setEmail("email@example.com");
                try {
                    user.signUp();
                } catch (ParseException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        });

谢谢

在使用 Parse 库之前，您必须调用 Parse.initialize(context, oauthKey, oauthSecret)。
