My web service outputs a JSON string that I need to parse.
Could you please tell me how i can parse the given JSON string:
{
"access_token":"kfwsfdcscfnsdcfsdsdfsd6f7df9sd6f89sd6s",
"expires_in":3600,
"token_type":"bearer",
"scope":null,
"refresh_token":"5dfddf1d6dfd1fddgdgdg1dg56d1"
}
JSONObject mainObject = new JSONObject(Your_Sring_data);
JSONObject uniObject = mainObject.getJSONObject("university");
String uniName = uniObject.getJSONObject("name");
String uniURL = uniObject.getJSONObject("url");
JSONObject oneObject = mainObject.getJSONObject("1");
String id = oneObject.getJSONObject("id");
refer this link:
http://stackoverflow.com/questions/8091051/how-to-parse-json-string-in-android
String jsonString = ""; //This'll contain the jsonString you mentioned above.
JSONObject object = new JSONObject(jsonString);
String accessToken = object.getString("access_token");
Similarly fetch other values.
{ // represents json object node
"access_token":"kfwsfdcscfnsdcfsdsdfsd6f7df9sd6f89sd6s", // key value pair
To parse
JSONObject jb = new JSONObject("jsonstring");
String acess_token = jb.getString("acess_token"); // acess_token is the key
// similarly others
You can also use Gson to convert json string to java object.
http://code.google.com/p/google-gson/
Using Gson
Download the jar add to the projects libs folder
Then
public class Response {
String acess_token,expires_in,token_typerefresh_token;
}
Then
InputStreamReader isr = new InputStreamReader (is);
Gson gson = new Gson();
Response lis = new Gson().fromJson(isr, Response.class);
Log.i("Acess Toekn is ",""+lis.expires_in);
JSONObject jsonObject = new JSONObject(jsonString);
