    }
}

Now in another activity i make the DatabaseAdapter object with the table name like this:

final DBAdapter db = new DBAdapter(this,table_name); // create new database with givan table name

Now while i fetch the data from that object, it gives me error like :

android.database.sqlite.SQLiteException: no such table: hello: , while compiling: INSERT INTO hello(word, title, sound, publisher, isbn) VALUES(?, ?, ?, ?, ?);

So where i am wrong? Why i am not able to create the table? What should i have to do ?

See This is My code of another activity from where i m calling the DBAdapter

  // database object        
    final DBAdapter db = new DBAdapter(this); // create new database with givan table name


    showall.setOnClickListener(new View.OnClickListener() 
    {

        public void onClick(View v) 
        {
            db.open();
            Cursor c = db.getAllTitles();
            while(c.moveToNext())        
            {
                Toast.makeText(EnterWordsActivity.this,
                        "id: " + c.getString(0) + "\n" + 
                        "ISBN: " + c.getString(1) + "\n" +  
                        "TITLE: " + c.getString(2) + "\n" + 
                        "WORD: " + c.getString(3) + "\n" +
                        "SOUND:" + c.getString(4) +"\n"+
                        "PUBLISHER:  " + c.getString(5),Toast.LENGTH_LONG).show();
            }
            db.close();
        }
    });

Error log after creating new table in to same database.
