Multidimensional array from JSON

Question

*** Code updated after recommendation **

Hi, I'm trying to parse a multidimensional array from json on my Android Project... I have read a lot of codes from other questions in stackoverflow but i can't understand very well how it works...

this is my JSON file:

http://pastebin.com/Vf4xWanC

and here is my code:

public String[][] parseJSON_canales() {
 JSONObject jsonObject = null;
 try {
 jsonObject = new JSONObject(json);
 enfrentan = jsonObject.getJSONArray(JSON_ENFRENTAMIENTOS);
 canales_recv = new String[enfrentan.length()][];
 for (int i = 0; i < enfrentan.length(); i++) {
 JSONObject jo = enfrentan.getJSONObject(i);
 todosCanales = jo.getJSONArray(JSON_CANALES);
 for (int j = 0; j < todosCanales.length(); j++) {
 JSONObject jo1 = todosCanales.getJSONObject(j);
 canales_recv[i][j] = jo1.getString(CANALES_OBTENIDOS);
 }
 }
 } catch (Exception e) {
 e.printStackTrace();
 Log.e("MYAPP", "exception: " + e.getCause());
 Log.e("MYAPP", "exception: " + e.toString());
 }
 return canales_recv;
}

I need to get "emite" values inside "equpos" array , any idea from what i'm doing bad?

• Nisarg: canales_recv[i][j] = jo.getString(CANALES_OBTENIDOS); // change jo to jo1

Answer 1

It Seems alright. BUT you are returning an empty String[][]

return new String[0][0];

you should return your "canales_recv" instead

return canales_recv;

And also as the comment said

canales_recv[i][j] = jo.getString(CANALES_OBTENIDOS); // change jo to jo1

• Lomunet Arratiko: In first place, thank you for your quickly response and help... I have made changes, but I get this error: 06-06 13:24:50.981 13661-13661/in.arenadroid.arenavision W/System.err: java.lang.NullPointerException: Attempt to write to null array
• Abdullah: can you please put a log before this line and check if there is any value canales_recv = new String[enfrentan.length()][]
• Lomunet Arratiko: Printing canales_recv.length: 06-06 13:33:47.228 17995-17995/in.arenadroid.arenavision I/System.out: MYAPP: canales_recv: 3 and LOG: pastebin.com/vdda67PS
• Abdullah: which one is the line no : 61
• Lomunet Arratiko: canales_recv[i][j] = jo1.getString(CANALES_OBTENIDOS)
