安卓中这些代码是什么意思？谁能帮我解答一下

public static final int ERROR_NETWORK = -100;
public static final int ERROR_Json_Format = -800;
public static final int NO_DATE= -101;

public static final int CMD_GET_LIST = 200;

public static final int CMD_Delete_LIST = 201;




public static final int CMD_LOGIN = 100;
public static final int CMD_GET_USER_LIST = 101;

网络状态信息，和网络登录请求标识，数字是随意的，
public static final int ERROR_NETWORK = -100;
public static final int ERROR_Json_Format = -800;
public static final int NO_DATE= -101;
这三个是代表返回的错误信息
public static final int CMD_GET_LIST = 200;
public static final int CMD_Delete_LIST = 201;
public static final int CMD_LOGIN = 100;
public static final int CMD_GET_USER_LIST = 101;
这四个是网络请求的标识，大概就是获取列表，删除列表，登录，和获取用户列表什么的
