will be something like (not tested, only written down...):
B4X: 
Dim jsonmap As Map
Dim dataList As List
Dim cols As Map
jsonmap.Initialize
dataList.Initialize
Dim maxi = 5

For i = 0 To maxi
  cols.Initialize
  cols.Put("name", "N"&i)
  cols.Put("id", i)
  cols.Put("family", "CC")
  dataList.Add(cols)

Next
jsonmap.put("data", dataList)
jsonmap.put("count", maxi)
jsonmap.Put("message", "OK")
Dim parser As JSONGenerator
parser.Initialize(jsonmap)
Log(parser.ToString)
