I am running into a syntax problem but I can't figure out what is wrong. It seems like this thread has the answer but it does work for me.
JSONException: Value of type java.lang.String cannot be converted to JSONObject
I am using Volley I need to extend the JsonObjectRequest so that I can access the http headers in the response. Here is my "CustomRequest"
public class CustomRequest extends JsonObjectRequest {
public CustomRequest(int method, String url, String jsonRequest,
Response.Listener<JSONObject> listener, Response.ErrorListener errorListener) {
super(method, url, jsonRequest, listener, errorListener);
}
@Override
protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {
try {
// Save http headers
mHeaders = response.headers;
String jsonString = new String(response.data,
HttpHeaderParser.parseCharset(response.headers, PROTOCOL_CHARSET));
return Response.success(new JSONObject(jsonString),
HttpHeaderParser.parseCacheHeaders(response));
} catch (UnsupportedEncodingException e) {
return Response.error(new ParseError(e));
} catch (JSONException je) {
return Response.error(new ParseError(je));
}
}
private Map<String, String> mHeaders = new HashMap<>();
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
return mHeaders;
}
}
and here my test class:
private void testVolleyRequest() {
String url = "http://my-json-feed";
CustomRequest jsonRequest = new CustomRequest
(Request.Method.GET, url, (String)null, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
Log.d("[TEST]", "Response: " + response.toString());
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.d("[TEST]", "error = "+error.toString());
}
});
Volley.newRequestQueue(this).add(jsonRequest);
}
If I try the sample above I keep getting:
com.android.volley.ParseError: org.json.JSONException: Value <html><head><meta of type java.lang.String cannot be converted to JSONObject
but I am returning a JSONObject:
return Response.success(new JSONObject(jsonString),
HttpHeaderParser.parseCacheHeaders(response));
if anyone can spot the issue I greatly appreciate.
thx!
