Sub GetPkg As List
    Dim pm As PackageManager
   Dim res As List
   res.Initialize
   For Each p As String in pm.GetInstalledPackages
    res.Add(CreateMap("package": p))
   Next

Hiding your code is the best way not to get help.
Create a map with most of the entries.
Then create a list and put two maps in it for the entries into this list.
add this list as to your 1st map with the key packages.

True. Sorry
B4X:
    Dim data As Map
    data.Initialize
    
    data.Put("devid",devid)
    data.Put("bateria",bateria)
    data.Put("latitud",latitud)

    Dim  d2 As JSONGenerator

Is this what you want?

B4X:
'Dim  d2 As JSONGenerator
'packages.Initialize
'Dim o As JSON = GetPkg
'd2.Initialize2(o)
'data.Put("packages",d2)
Dim packages As List
packages.Initialize
packages.Add(CreateMap("package": "youtube"))
packages.Add(CreateMap("package": "amazon"))
data.Put("packages", packages)

'Dim  d As JSONGenerator
'd.Initialize(data)
'Log(d.ToString)
Log(data.As(JSON).ToString)
