有关于郭大神《第一行代码》酷欧天气遇到的问题

在ChooseAreaFragment中，代码全部敲完以后，运行app时遇到了，闪退现象，查看logcat，遇到如下错误

报错上写的是：can not find a class named com.example.lrx.coolweather.android.db.Province
而根据你的截图上来看，你的Province是com.example.lrx.coolweather.db.Province，中间少了一个android

修改litepal.xml文件为：
<?xml version="1.0" encoding="utf-8"?>

地址指的是class文件的地址。

错误如下：09-01 11:01:55.619 3833-3833/? E/AndroidRuntime: FATAL EXCEPTION: main

其中，显著错误为： java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.lrx.coolweather/com.example.lrx.coolweather.MainActivity}: org.litepal.exceptions.DatabaseGenerateException: can not find a class named com.example.lrx.coolweather.android.db.Province。
结合在网上寻找的解答方法，大致为litepal中的包名路径不一致等，检查无误后还是这样，请解答

代码没有抄对，建议按照这个复制粘贴：https://blog.csdn.net/aiyuan1996/article/details/52497035

com.example.lrx.coolweather.android.db.Province 这个引用province的时候 把前面的.android去掉 应该就行了
