Here's the JSON response.
The following works:
jsonObject.get("title").getAsString();
jsonObject.get("author").getAsJsonObject().get("profile_photo").getAsString();
but jsonObject.get("primary_photo").getAsString() (from line 60) returns an Unsupported Exception: null error. I've tried replacing getAsString() with toString() but the latter returns an empty string.
Try this
Use optJSONObject and optString in your code . And the root is [],so you should use JSONArray
try {
JSONArray jsonArray = new JSONArray(response);
for (int i = 0; i < jsonArray.length(); i++) {
// use optJSONObject
JSONObject author = jsonArray.optJSONObject(i).optJSONObject("author");
// use optString , it did not return null
String profile_photo = author.optString("profile_photo");
String primary_photo = jsonArray.optJSONObject(i).optString("primary_photo");
}
} catch (JSONException e) {
e.printStackTrace();
}
Gson
JsonArray jsonElements = new JsonParser().parse(response).getAsJsonArray();
for (int i = 0; i < jsonElements.size(); i++) {
JsonObject jObject = jsonElements.get(i).getAsJsonObject();
// edited here
String primary_photo = jObject.get("primary_photo").getAsString();
JsonObject author = jObject.getAsJsonObject("author");
String profile_photo = author.get("profile_photo").getAsString();
}
primary_photo key (line 60).
author.optString("author") be author.optString("primary_photo")?String primary_photo = jsonArray.optJSONObject(i).optString("primary_photo"); in your code .I think the Problem is, that your JSON response contains an Array. You have to create an JSONArray from the response-string and than iterate about it to get your values. Or if this array always contains one object:
JSONArray jsonArray = new JSONArray(response);
JSONObject jsonObject = jsonArray.getJSONObject(0);
for loop.
Try this,
try {
JSONArray jsonArray = new JSONArray(response);
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject author = jsonArray.get(i).getJSONObject"author");
String profile_photo = author.getString("author");
}
} catch (JSONException e) {
e.printStackTrace();
}
Try this:
try {
JSONArray jarr=new JSONArray(response); // response is whole json response
for (int i=0;i<jarr.length();i++){
JSONObject jobj=jarr.getJSONObject(i);
String primary_photo=jobj.getString("primary_photo");
}
} catch (JSONException e) {
e.printStackTrace();
}
