I do not understand why this query does not work in android and "Graph Api Explorer" if it
111891332274505?fields=albums.fields(id,name,description,updated_time,created_time,cover_photo)
Error Code
Error code: 2500 Error mensaje: {HttpStatus: 400, errorCode: 2500, errorType: OAuthException, errorMessage: Syntax error "Expected end of string instead of "?"." at character 6: photos?access_token=XXXXXXXXXXXX}
Code
public void getAlbumFacebook () {
Request request = new Request(session, "/111891332274505?fields=albums.fields(id,name,description,updated_time,created_time,cover_photo)", null, HttpMethod.GET, new Request.Callback() {
@Override
public void onCompleted(Response response) {
GraphObject graphObject = response.getGraphObject();
FacebookRequestError error = response.getError();
if (error != null) {
DebugLog.log("Error code: " + error.getErrorCode() + " Error mensaje: " + error.toString());
}
if (graphObject != null) {
JSONArray jsonArray = (JSONArray) graphObject.getProperty("data");
DebugLog.log("JSON Facebook "+ jsonArray.toString());
} else {
DebugLog.log("Es null");
}
}
});
Request.executeBatchAsync(request);
}
SOLUTION
I've already been able to solve the problem I can deduce is that the "Request" class can not consult with inserted fields.
In the end what I have done is to build the url and request data through the url.
Build URL
String id = "111891332274505";
String url = "https://graph.facebook.com/" + id + "/albums?access_token=" + session.getAccessToken() + "&fields=id,name,description,updated_time";
Code request
public JSONObject getRequestFromUrl (String url) {
try {
httpClient = new DefaultHttpClient();
HttpGet get = new HttpGet(url);
HttpResponse httpResponse = httpClient.execute(get);
HttpEntity responseEntity = httpResponse.getEntity();
is = responseEntity.getContent();
DebugLog.log("Estoy aqui");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
Log.e("JSON", json);
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
return jObj;
}
There should be an ampersand sign & just before the access_token
parameter. But right now, a ? is being appended before that parameter. The problem is the part of the code that is appending the ? instead of & in the URL.
