SQLite高级：一库建多表，封装类

package eoe.database;

import android.content.Context;

import android.database.sqlite.SQLiteDatabase;

import android.database.sqlite.SQLiteOpenHelper;

import android.util.Log;

/**

* 默认就在数据库里创建4张表

*/

}

@Override

自定义数据库服务封装类：

import com.yangguangfu.bean.ConfigInfo;

import com.yangguangfu.bean.InstallInfo;

import com.yangguangfu.bean.SMSInfo;

/**

* 数据库方法封装，创建表，删除表，数据(增删该查)...
