Estou trabalhando em um CRUD do Android, mas ele não quer criar o arquivo dentro da pasta do sistema:

//view de listagem



package com.example.rlsystemcrud;



import android.content.Context;

import android.database.sqlite.SQLiteDatabase;

import android.os.Bundle;

import android.support.v7.app.ActionBarActivity;



public class listar extends ActionBarActivity{

	

	@Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.listar);

        

        

        SQLiteDatabase db = openOrCreateDatabase("clientes.db", Context.MODE_PRIVATE, null);

        

        //tabelas

        

        StringBuilder bdClientes = new StringBuilder();

        bdClientes.append("CREATE TABLE IF NOT EXISTS clientes (");

        bdClientes.append("_id INTEGER PRIMARY KEY, ");

        bdClientes.append("nome VARCHAR(30), ");

        bdClientes.append("email VARCHAR(10));");

        db.execSQL(bdClientes.toString());

    }



}
