JSON-Lib:READ JSON FILE

Step 1：get String

File file = new File(mapFilePath);
StringBuffer sb = new StringBuffer();
try {
	InputStreamReader reader = new InputStreamReader(new FileInputStream(file), "UTF-8");
	BufferedReader bufferedReader = new BufferedReader(reader);
	String temp = "";
	while ((temp = bufferedReader.readLine()) != null) {
		sb.append(temp);
	}
	bufferedReader.close();
} catch (Exception e) {
	e.printStackTrace();
}

Step 2:transform to JSONArray/JSONObject

JSONArray jsonArray = JSONArray.fromObject(sb.toString())
JSONObject jsonObject = JSONObject.fromObject(sb.toString());
