&
Defense"},{"key":72,"value":"Automotive"},{"key":83,"value":"Banking"},{"key":84,"value":"Biotech"},{"key":85,"value":"Construction"},{"key":86,"value":"Customer

I want to decode it on my Android App, This is the code i have used., But
i don't get anything on my output. No errors too.
JSONObject jObject= new JSONObject();
JSONArray menuObject = new JSONArray(jObject.getString("JSONDATA"));
String app;
for (int i = 0; i<menuObject.length(); i++) {
{
app=menuObject.getJSONObject(i).getString("value").toString();
a.append(app); // a is my TextView
}
