如何连接一个sqlite数据库（sqlite firefox扩展）到android应用程序，用于android 2.1来查询并插入到数据库

我正在开发一个android应用程序，用户应该输入一些函数：register，locate hospital位置，搜索消息（通过短信发送给注册用户），并可以安排和预约。到目前为止，所有的活动都完成了，但是我需要知道如何连接到数据库才能读取和存储这些数据。我正在使用Android 2.1，MacOsX和SQLite firefox扩展。如何连接一个sqlite数据库（sqlite firefox扩展）到android应用程序，用于android 2.1来查询并插入到数据库

这是我必须连接到sqllite db的代码，我做错了什么？

package com.bitnuts.imom; 

import java.io.FileOutputStream; 
import java.io.IOException; 
import java.io.InputStream; 
import java.io.OutputStream; 

import android.content.Context; 
import android.database.sqlite.SQLiteDatabase; 
import android.database.sqlite.SQLiteOpenHelper; 

public class DbManager extends SQLiteOpenHelper { 

    private static final String DB_NAME = "iMom.sqlite"; 
    private static final String DB_PATH = "/data/data/com.bitnuts.imom/databases/"; 
    private static final Integer DB_VERSION = 1; 
    private static final String TAG = "DbManager"; 
    private final Context context; 
    private SQLiteDatabase db; 
    private DbManager dbManager; 

    public DbManager(Context context) { 
     super(context, DB_NAME, null, DB_VERSION); 
     this.context = context; 
    } 

    public DbManager open() { 
     dbManager = new DbManager(context); 
     db = dbManager.getWritableDatabase(); 
     return this; 

    } 

    @Override 
    public void onCreate(SQLiteDatabase arg0) {  


     createNewDatabase(); 
    } 

    @Override 
    public void onUpgrade(SQLiteDatabase arg0, int arg1, int arg2) { 
     // TODO Auto-generated method stub 

    } 

    public void createNewDatabase() { 
     InputStream assetsDB = null; 
     try { 
      assetsDB = context.getAssets().open(DB_NAME); 
      OutputStream dbOut = new FileOutputStream(DB_PATH + DB_NAME); 

      byte[] buffer = new byte[1024]; 
      int length; 
      while ((length = assetsDB.read(buffer)) > 0) { 
       dbOut.write(buffer, 0, length); 
      } 

      dbOut.flush(); 
      dbOut.close(); 
      assetsDB.close(); 
     } catch (IOException e) { 

     } 
    } 
}
