No, you cannot add keys inside a JSONArray. You can do that inside a JSONObject though.

Two approaches:

  1. With JSONArray (Acts Like A List):

    JSONArray jsonArray = new JSONArray();

JSONObject caloriesJSON = new JSONObject();
caloriesJSON.put("calories_burn", 345);
caloriesJSON.put("time", dp.getTimestamp(TimeUnit.MILLISECONDS));

JSONObject stepsJSON = new JSONObject();
stepsJSON.put("steps", "12121");
stepsJSON.put("time", dp.getTimestamp(TimeUnit.MILLISECONDS));

jsonArray.put(stepsJSON);
jsonArray.put(caloriesJSON);

  2. With JSONObject(Acts Like A Map/Dictionary):

    JSONObject jsonObject = new JSONObject();

JSONObject caloriesJSON = new JSONObject();
caloriesJSON.put("calories_burn", 345);
caloriesJSON.put("time", dp.getTimestamp(TimeUnit.MILLISECONDS));

JSONObject stepsJSON = new JSONObject();
stepsJSON.put("steps", "12121");
stepsJSON.put("time", dp.getTimestamp(TimeUnit.MILLISECONDS));

jsonObject.put("steps",  stepsJSON);
jsonObject.put("calories", caloriesJSON);

Be careful what you put for values. "12313" is a String whereas 345 is an integer.

You are falling in between two patterns, you can either use it as a map, or an array.

Map approach:

{
  "steps": { "steps":123, "time": 123 },
  "calories": { and so},
  "bpm": { on }
}

Code (untested, think and tweak)

// Build your objects
JSONObject steps = new JSONObject();
steps.put("steps", 123);
steps.put("time" 123);
JSONObject calories = new JSONObject();
//And so on
JSONObject bpm = new JSONObject();

//Make a map
JSONObject map = new JSONObject();
//Add to the map:
map.put("steps", steps);
map.put("calories", calories);
map.put("bpm", bpm);
