assets目录下存放的原生资源文件,通过getAssets()方法获取.

使用：

InputStream inputStream;            try {                inputStream = getAssets().open("data/chat.isp");                String json = StringUtil.readTextFile(inputStream);                JSONArray array = new JSONArray(json);                backModel result = null;                for (int i = 0; i < array.length(); i++) {                    result = new backModel();                    result.setTime(array.getJSONObject(i).getString("time"));                    result.setContent(array.getJSONObject(i).getString("content"));                    backModels.add(result);                }            } catch (IOException e) {                e.printStackTrace();            } catch (JSONException e) {                e.printStackTrace();            }

其中数据存在于assets\data\chat.isp文件中：

[{"time":"14:25:29","content":"在么?,","type":"1"},{"time":"14:26:18","content":"嗯,在的,","type":"2"}]
