我正在制作一个Android应用程序，它包含一个使用SMS验证的简单登录。使用Spring MVC进行Web服务。
这是我的android代码：

错误显示手机是布尔值而不是字符串，但我检查了它的布尔值
这是我的配置文件：
package net.simplifiedcoding.androidotp;
public class Config {
//URLs to register.php and confirm.php file
public static final String REGISTER_URL = "http://10.0.2.2:8080/FinalSmsApi/rest/requestSms/hello";
public static final String CONFIRM_URL = "http://10.0.2.2:8080/FinalSmsApi/rest/confirm";
//Keys to send username, password, phone and otp
public static final String KEY_USERNAME = "username";
public static final String KEY_PASSWORD = "password";
public static final String KEY_PHONE = "phone";
public static final String KEY_OTP = "otp";
//JSON Tag from response from server
public static final String TAG_RESPONSE= "ErrorMessage";
}
