java - can't find databases folder under data/data/packagename/ using eclipse android emulator -

i'm having problem sqlite android. according examples found internet, databases can found under data/data/packagename/ can't find folder under directory.

please tell me what's problem?

and provide sqlitehelper class in case if it's necessary .

   package com.example.waterrefilltest;   import static android.provider.basecolumns._id;     import android.content.contentvalues;  import android.content.context;  import android.database.sqlite.sqlitedatabase;  import android.database.sqlite.sqliteopenhelper;       public class data extends sqliteopenhelper{   private static final string database_name = "waterrefill.db";  public data(context ctx){     super(ctx, database_name, null, 4); }    public void generatedata(content c){     sqlitedatabase db = this.getwritabledatabase();     contentvalues cv = new contentvalues();     cv.put("lat", c.getlat());     cv.put("long", c.getlng());     cv.put("cat",c.getct());     cv.put("rat", c.getrt());     cv.put("ph",c.getph());     cv.put("distance", c.getdistance());     db.insert("contents", null, cv);     db.close(); }  public void deletedata(sqlitedatabase db){     db.execsql("drop table contents");  } @override public void oncreate(sqlitedatabase db){     db.execsql("create table contents ("+_id+" integer primary key autoincrement , lat text ,  longi text , cat text , rat text , ph text , distance text );"); }  @override public void onupgrade(sqlitedatabase db, int oldversion, int newversion) {     db.execsql("drop table if exists contents");     oncreate(db);    } 

}

i guess databse not created yet. thats why not able see it. try in mainactivity class:

data dt = new data(this); sqlitedatabase db = dt.getreadabledatabase(); 

database created when oncreate called , when call getreadabledatabase() oncreate called , database created
