public void testJsonMapper() throws Exception
{
DatabaseHelper helper = DatabaseHelper.getHelper(getContext());
// Load JSON
JSONObject json = JsonLoader.loadObject(getContext(), poetry.test.R.raw.test);
// Get child arrays from JSON
JSONArray users_json = JsonPathResolver.resolveArray(json, "users");

// Persist arrays to database
JsonPersister persister = new JsonPersister(helper.getWritableDatabase());
