Question

我在Constant_Country类中遇到java.lang.NoClassDefFoundError错误，该错误存在于com.mi.uVite.model包中。

类仍然存在它仍然显示NoClassDefFoundError。我怎样才能克服这个问题？

java.lang.NoClassDefFoundError: com.mi.uVite.model.Constant_Country
        at com.mi.uVite.db.MIDatabaseHandler.createCountryTable(MIDatabaseHandler.java:911)

并且

public class Constant_Country
{
public static String country_id = "country_id";
public static String country_short_code = "country_short_code";
public static String country_name = "country_name";
public static String country_code = "country_code";
}

Answer 1

我认为你必须将类Constant_Country添加到包com.mi.uVite.model并放入Constant_Country的第一行

package com.mi.uVite.model

请记住，如果使用Constant_Country类型的对象，则必须使用导入。

java.lang.NoClassDefFoundError
