Contentful Product Catalogue Error

I have download this CONTENTFUL CMS product catalogue demo ->http://ift.tt/1jEzqee. Im using android studio 1.4. I have set the public token ID in the const.java accordingly but it still get error. At first i think maybe i have set a wrong setting at content_type field setting. But i still cannot find my solution. My error look like below and ive attached images for you to see,

10-23 18:56:18.820 2094-2147/catalogue.contentful E/SQLiteLog: (1) no such table: entry_nulundg0rwhzuvm0suntyxvdzufjrq
 (1) no such table: entry_ne90ogm2rdjxuxfnb2fvs2dzbtgysw

}

And this is my Android Studio coding

  public Product$$ModelHelper() {
    fields.add(FieldMeta.builder().setId("productName").setName("name").setSqliteType("STRING").build());
    fields.add(FieldMeta.builder().setId("productDescription").setName("description").setSqliteType("STRING").build());
    fields.add(FieldMeta.builder().setId("sizetypecolor").setName("sizeTypeColor").setSqliteType("STRING").build());
    fields.add(FieldMeta.builder().setId("image").setName("images").setArrayType("com.contentful.vault.Asset").build());
    fields.add(FieldMeta.builder().setId("tags").setName("tags").setSqliteType("BLOB").setArrayType("java.lang.String").build());
    fields.add(FieldMeta.builder().setId("categories").setName("categories").setArrayType("catalogue.contentful.vault.Category").build());
    fields.add(FieldMeta.builder().setId("price").setName("price").setSqliteType("DOUBLE").build());
    fields.add(FieldMeta.builder().setId("brand").setName("brand").setLinkType("ENTRY").build());
    fields.add(FieldMeta.builder().setId("quantity").setName("quantity").setSqliteType("INT").build());
    fields.add(FieldMeta.builder().setId("sku").setName("sku").setSqliteType("STRING").build());
    fields.add(FieldMeta.builder().setId("website").setName("website").setSqliteType("STRING").build());
  }

  @Override
  public List<FieldMeta> getFields() {
    return fields;
  }

  @Override
  public String getTableName() {
    return "entry_ne90ogm2rdjxuxfnb2fvs2dzbtgysw";
  }

think where the error is]1

When i look again I really appreciate if anyone can help me with this problem.Because this app is a demo, i really think my problem is at my setting at CONTENTFUL, but maybe i need second opinion. Please help.

Thank you.
