Error You Already Own This Item

I have a new android app in which I am adding in-app billing and I am tearing my hair out with frustration.
I have uploaded a signed APK and published to alpha. I created a set of in-app products and activated them all. I have created a new gmail account and defined them as a tester for the app on the app apk page.
I have factory reset my android phone and initialised it with the new gmail account. I have entered the /apps/testing link in to chrome and signed up as a tester. I then downloaded and installed my app. Inside my app I asked for the in app products that were available and was shown the set i created above. I selected one to buy and went through the following purchase process.
1. Screen shows product to be purchased and price and requests press continue which i do
2. Screen shows payment methods and I select redeem code
3. Screen shows redeem your code and I enter one of the promotion codes I set up in the developer console earlier (not mentioned above - sorry) and press redeem
4. Screen shows product again, this time with price crossed out and offers option to add item which I select (very strange being asked to add again buy hey ho)
5. Screen shows item added
6. After a fews seconds screen shows Error you already own this item.
How can this be, this user did not exist before ten minutes ago and has only used this app once as described above.
I have seen many questions in stack overflow and elsewhere similar to this and tried everything, clearing google play store cache, clearing google play store data etc. This sequence described above is my latest attempt with a completely clean user on a completely clean phone.
I could upload my app code used but that misses the point, which is how can this gmail account already own an item when this gmail account have never purchased anything before from anyone. Surely this is a bug.
All clues very welcome as to how to proceed. Code now added, note this is a hybrid android app, with the user purchase decisions code in javascript/html and the in app actions in the wrapper code below
private void processCommand(JSONObject commandJSON) throws JSONException
{
String command = commandJSON.getString("method");

{
Log.d(TAG, "Returned from InAppProductPurchased:");
}
}
);
}
}
};

I have found that this error does not occur when using paypal (i.e. real money) to make the purchase, so I believe that this "Error you already own this item" message is in some way connected to using a promotion code for the test. And (so far) my paypal account has not been charged (as I am a resgistered tester for the app).

Add new row in Parse class using Android

Can't create a new row in using Parse in android. I am able to retrieve, but when I try to add a new row like this, I keep getting false and new row is not being created.
What am I doing wrong here ?
I am exactly following what is given in Parse-Android documentation.
ParseObject storyActivity = new ParseObject("StoryActivity");
storyActivity.put("createdByUser", user);
storyActivity.put("story", story);
storyActivity.put("type", likeUnlike);
return storyActivity.saveInBackground().isCompleted();

Check class level permission Write under class StoryActivity's Security on console.

Call that in following way -
ParseObject storyActivity = new ParseObject("StoryActivity");
storyActivity.put("createdByUser", user);
storyActivity.put("story", story);
storyActivity.put("type", likeUnlike);
storyActivity.saveInBackground(new SaveCallback() {
public void done(ParseException e) {
if (e == null) {
// your object is successfully created.
} else {
//error occurred
Toast.makeText( context,e.getMessage().toString(),Toast.LENGTH_LONG );
}
}
});
So, by this toast message you can know what is reason of problem you are getting.

Try on this way to set read write permission when user insert/ update record in parse database like ...
ParseObject storyActivity = new ParseObject("StoryActivity");
storyActivity.put("createdByUser", user);
storyActivity.put("story", story);
storyActivity.put("type", likeUnlike);
// here first set read write permission like ..
// when user update value ya insert new value in database
ParseACL postACL = new ParseACL(ParseUser.getCurrentUser());
postACL.setPublicReadAccess(true);
postACL.setPublicWriteAccess(true);
storyActivity.setACL(postACL);
storyActivity.saveInBackground(new SaveCallback() {
#Override
public void done(ParseException e) {
// TODO Auto-generated method stub
if (e == null) {
// success
} else {
// fail
Log.e("Tag", "getting to fail " + e.getMessage());
}
}
});

Android - Parse - deleteInBackground, record not being deleted

I'm using Parse with Android in order to sync my data.
I'm trying to delete an object which is stored in the Parse cloud via
The callback returns and there's no exception, the Logcat message is "deleted".
But the object still exists in table when I check the Parse Data.
tastToEdit is an object from Task class (configured locally in my app).
ParseObject parse_task = new ParseObject("Task");
parse_task.put("Description",tastToEdit.getDescription());
parse_task.put("DueDate",tastToEdit.getDueDate());
parse_task.put("Priority",tastToEdit.getPriority().ordinal());
int com_state = (tastToEdit.getCompleted()) ? 1 : 0;
parse_task.put("IsCompleted",com_state);
parse_task.put("Location",0);
parse_task.put("Category",tastToEdit.getTask_catg().ordinal());
parse_task.put("Status", tastToEdit.getTask_sts().ordinal());
//parse_task.deleteInBackground();
parse_task.deleteInBackground(new DeleteCallback() {
public void done(ParseException e) {
if (e == null) {
Log.d("msg","deleted");
} else {
Log.d("msg", "not deleted");
e.printStackTrace();
}
}
});
What might be causing the callback to return as "deleted" but the object still remains?
Thanks in advance.

You are creating a new ParseObject and you try to delete it after but you don't provide an ObjectID.
A better way to do this will be to first do a ParseQuery for that task you are looking and the in the completion delete it.

How to upload multiple images on Parse?

I need help with Parse Android API and images uploading/updating. User in my app can create event that has 1 or more images related to that event. So, this images are stored as array object that have parse files.
User can edit images that he added for that event. So, user might want to delete image or to add a new image. So, there I have problem, how I can edit array to delete specific image.
My idea was to download all images on the phone, and when user add/delete image update it locally and then upload again all images to Parse and update that array of images, but it seems that is not working properly, since I get only one image uploaded.
How I can solve this problem, any idea is appreciated.
for (int i = 0; i < ImagesSingleton.getInstance().getBytesList().size(); i++) {
String fileName = FileHelper.getFileName(getActivity(), ImagesSingleton.getInstance().getUrisList().get(i), "image");
byte[] b = ImagesSingleton.getInstance().getBytesList().get(i);
final ParseFile imgFile = new ParseFile(fileName, ImagesSingleton.getInstance().getBytesList().get(i));
imgFile.saveInBackground(new SaveCallback() {
#Override
public void done(com.parse.ParseException e) {
if (e == null) {
listOfFiles.add(imgFile);
if (listOfFiles.size() == ImagesSingleton.getInstance().getUrisList().size()) {
offer.put(ParseConstants.OFFER_PICTURES, listOfFiles);
offer.saveInBackground(new SaveCallback() {
#Override
public void done(com.parse.ParseException e) {
if (e == null) {
mProgressDialog.dismiss();
Toast.makeText(getActivity(), "Sucess saving", Toast.LENGTH_SHORT).show();
ImagesSingleton.getInstance().reset();
transferToRadar();
} else {
mProgressDialog.dismiss();
Toast.makeText(getActivity(), getResources().getString(R.string.error) + e.getLocalizedMessage(), Toast.LENGTH_SHORT).show();
}
}
});
}
}
}
});
}

I think it is quite clear in documentation how to delete an element(s) from an Array column in Parse. You simply have to send the list of the files you want to be removed from the Array like this:
offer.removeAll(ParseConstants.OFFER_PICTURES, listOfFilesToRemove);
offer.saveInBackground();

my query.findInBackground not getting executed in android

I am using parse for my data in android app. for some reason the code inside query.findInBackground is not getting executed.
public List<Date> sessionHeaderFetch(){
Log.d("test", "session fetch entry");
ParseQuery<Sessions> query = ParseQuery.getQuery(Sessions.class);
final List<Date> sessionHeaders = null;
query.findInBackground(new FindCallback<Sessions>() {
#Override
public void done(List<Sessions> sessionsObjects, com.parse.ParseException e) {
Log.d("test", "session internal entry");
if (e == null) {
Log.d("test", "Retrieved " + sessionsObjects.size() + " sessions");
for (Sessions session : sessionsObjects) {
sessionHeaders.add(session.getNetsDate());
};
} else {
Log.d("score", "Error: " + e.getMessage());
}
}
});
Log.d("test", "session last value");
return sessionHeaders;
}
the code inside public void done() is not all invoked.

I don't think you have understood how to query correctly in Parse.
When you define the parse query. The get query should contain the name of the table that you are trying to query. Also the queries returned will be ParseObjects normally, so I would expect that your callback should be new FindCallback().
I've adjusted the parse query below.
ParseQuery<Sessions> query = ParseQuery.getQuery("ParseTableName");
final List<Date> sessionHeaders = null;
query.findInBackground(new FindCallback<ParseObject>() {
#Override
public void done(List<ParseObject> sessionsObjects, com.parse.ParseException e) {
Log.d("test", "session internal entry");
if (e == null) {
// Find succeeded, so do something
} else {
Log.d("score", "Error: " + e.getMessage());
}
}
});
Obviously you will need to replace "ParseTableName" with the name of the table that you are trying to query in parse.

I actually solved it by using an ArrayList, there were some problems with the List initialization and also the results are fetched asynchronous manner so my functions which calls these functions were getting null values so I had to write by calling functions that calls the parse fetch functions asynchronously as well.
but the query can be written like this and it works.
public void sessionFetch(Date headers, final ParseIOListener<Sessions> listener){
ParseQuery<Sessions> query = ParseQuery.getQuery(Sessions.class);
Log.d("test", "input header" + headers );
query.whereEqualTo("NetsDate",headers);
final ArrayList<Sessions> sessionsData = new ArrayList<Sessions>();
query.findInBackground(new FindCallback<Sessions>() {
#Override
public void done(List<Sessions> sessionsObjects, com.parse.ParseException e) {
if (e == null) {
for (Sessions session : sessionsObjects) {
Log.d("test", "output objects" + session.toString() );
sessionsData.add(session);
Log.d("test", "Retrieved -- sessions" + sessionsObjects.size() );
}
listener.onDataRetrieved(sessionsData);
} else {
listener.onDataRetrieveFail(e);
}
}
});
}
If you want more details on implementing this, check this link

The reason why you feel the code is not being invoked is because you are returning from the method before the ".findInBackground" operation has completed. Remember the query is performed on a background thread. So this is how your code will run:
ParseQuery query = ParseQuery.getQuery(Sessions.class);
final List sessionHeaders = null;
------> 1. query.findInBackground (Popped onto background thread)
return sessionHeaders; (by the time you get here, sessionHeaders will probably still be null).
So change the logic of the code and wait till the callback returns before doing any processing on the "sessionHeaders" object.
