Hi,

I have one 'progressCollection' in which i have following column

group_id,

challengid,

progress,

date,

timestamp,

overallprogress,



I am trying to fetch all data of 'progressCollection' using my group_id, Si i am passing group id but i am getting null pointer Exception.



`Query myQuery = mKinveyClient.query();

myQuery.equals("group_id",groupId);

AsyncAppData myEvents = mKinveyClient.appData("ProgressCollection", ProgressEntity.class);

myEvents.get(myQuery, new KinveyListCallback() {

@Override

public void onSuccess(ProgressEntity[] results) {

Log.v("WILL", "progress by specific group "+ results.length + " events and givenName = "+results);

groupsInMyChallenge = results.length;

List myList = Arrays.asList(results);



}

@Override

public void onFailure(Throwable error) {

Log.e("TEST", "failed to fetchByFilterCriteria", error);

}

});`



I also create GenericJSON class.



`public class ProgressEntity extends GenericJson {

@Key("_id")

private String id;

@Key

private int group_id;

@Key

private int challangeid;

@Key

private String date;

@Key

private boolean overallprogress;

@Key

private long timestamp;

@Key

private String progress;

@Key("_kmd")

private KinveyMetaData meta; // Kinvey metadata, OPTIONAL

@Key("_acl")

private KinveyMetaData.AccessControlList acl; //Kinvey access control, OPTIONAL

public ProgressEntity(){} //GenericJson classes must have a public empty constructor

}`





Here is Exception which i really don't know why i am getting..

My all other fetching and saving code working fine except this one.



Thanks in Advance.

Hey--



at a glance that code all looks correct, can you enable debug logging by taking a look at this guide: http://devcenter.kinvey.com/android/guides/troubleshooting



That will dump all http requests and responses to the logs, can you post those here as they might give some insight into what is going on?
