first you need to read the json file from assets , you can use this method

public String readFile(String fileName) throws IOException
{
  BufferedReader reader = null;
  reader = new BufferedReader(new InputStreamReader(getAssets().open(fileName), "UTF-8")); 

  String content = "";
  String line;
  while ((line = reader.readLine()) != null) 
  {
     content = content + line
  }

  return content;

}

then

String jsonFileContent = readFile("json_in_assets.json");
JSONArray jsonArray = new JSONArray(jsonFileContent);
List persons = new ArrayList<>();
for (int i=0;i
