Android- create JSON Array and JSON Object

Question

How can I create a JSON with this format in Android  Since the API that I will be passing will parse JsonArray then the object  Or would it be okay if just to pass a json object  Since I will just have to insert 1 transaction per service  call          student                            id   1               name    John Doe                year    1st                curriculum    Arts                birthday   3 3 1995                                   id   2               name    Michael West                year    2nd                curriculum    Economic                birthday   4 4 1994                     What I know is only the JSONObject  Like this one   JSONObject obj   new JSONObject    try       obj put  id    3        obj put  name    NAME OF STUDENT        obj put  year    3rd        obj put  curriculum    Arts        obj put  birthday    5 5 1993      catch  JSONException e           TODO Auto-generated catch block     e printStackTrace        Any ideas  Thanks

Use the following code   JSONObject student1   new JSONObject    try       student1 put  id    3        student1 put  name    NAME OF STUDENT        student1 put  year    3rd        student1 put  curriculum    Arts        student1 put  birthday    5 5 1993       catch  JSONException e           TODO Auto-generated catch block     e printStackTrace       JSONObject student2   new JSONObject    try       student2 put  id    2        student2 put  name    NAME OF STUDENT2        student2 put  year    4rd        student2 put  curriculum    scicence        student2 put  birthday    5 5 1993       catch  JSONException e           TODO Auto-generated catch block     e printStackTrace        JSONArray jsonArray   new JSONArray     jsonArray put student1   jsonArray put student2    JSONObject studentsObj   new JSONObject        studentsObj put  Students   jsonArray      String jsonStr   studentsObj toString         System out println  jsonString    jsonStr

Have been struggling with this till I found out the answer    Use GSON library   Gson gson   Gson    String str json   gson tojson jsonArray     Pass the json array  This will be auto stringfied  This option worked perfectly for me

Here s a simpler  but not so short  version which doesn t require try-catch   Map lt String  String gt  data   new HashMap lt  gt     data put  user    mark facebook com    data put  pass    123     JSONObject jsonData   new JSONObject data     If you want to add a jsonObject into a field  you can do this way   data put  socialMedia    new JSONObject    put  facebookId    1174989895893400     data put  socialMedia    new JSONObject    put  googleId    106585039098745627377       Unfortunately it needs a try-catch because of the put   method   IF you want to avoid try-catch again  not very recommended  but it s ok if you can guarantee well formated json strings   you might do this way   data put  socialMedia       facebookId    1174989895893400         You can do the same about JsonArrays and so on    Cheers
