Android: Receiving wrong UTM from Google Ads

According to my boss, some of our applications have been invested on advertising of the app via Google Ads. In order for them to parse the data and analyze them correctly, they are using the UTM auto-tagging approach. It is my job from the client (Android Device) to send the UTM using Firebase Analytics and also a custom event to Firebase depending on this UTM.
However, our data shows that both Firebase SDK and our events are transferred incorrectly. The click numbers and the download numbers do not match. Since both of them are incorrect, I'm guessing the received UTM on the device itself is wrong, and this needs to be received correctly and I am unable to find an answer for this.
I'm using Install Referrer Library to track down what the UTM is after the app is downloaded to the device. I am guessing Firebase SDK also uses somewhat similar approach. On our end, the UTM is recorded to SharedPreferences and it is not queried again if the query was successful.
Here is the related code for it (the processReferrer method basically parses the UTM according to our needs):
/**
* Checks if the referrer information is recorded before, if not, creates
* a connection to Google Play and saves the data to shared preferences.
*/
private static void fetchReferrerInformation(Context context)
{
SharedPreferences preferences =
PreferenceManager.getDefaultSharedPreferences(context);
String utmData = preferences.getString(UTM_DATA, "");
// Only connect if utm is not recorded before.
if (TextUtils.isEmpty(utmData))
{
InstallReferrerClient client;
try
{
client = InstallReferrerClient.newBuilder(context).build();
client.startConnection(new InstallReferrerStateListener()
{
#Override
public void onInstallReferrerSetupFinished(int responseCode)
{
switch (responseCode)
{
case InstallReferrerClient.InstallReferrerResponse.OK:
{
ReferrerDetails response;
try
{
response = client.getInstallReferrer();
}
catch (Exception e)
{
Log.e(TAG, "Error while fetching referrer information.", e);
if (Fabric.isInitialized())
Crashlytics.logException(new IllegalStateException("Exception while fetching UTM information.", e));
return;
}
if (response != null)
{
processReferrer(context, response.getInstallReferrer());
}
break;
}
case InstallReferrerClient.InstallReferrerResponse.FEATURE_NOT_SUPPORTED:
{
Log.w(TAG, "Install referrer client: Feature is not supported.");
break;
}
case InstallReferrerClient.InstallReferrerResponse.SERVICE_UNAVAILABLE:
{
Log.w(TAG, "Install referrer client: Service is unavailable.");
break;
}
}
try
{
client.endConnection();
}
catch (Exception ignored){}
}
#Override
public void onInstallReferrerServiceDisconnected()
{
// Do nothing, we need to fetch the information once and
// it is not really necessary to try to reconnect.
// If app is opened once more, the attempt will be made anyway.
}
});
}
catch (Exception e)
{
if (Fabric.isInitialized())
Crashlytics.logException(new IllegalStateException("Exception while fetching UTM information.", e));
}
}
else
Log.i(TAG, "UTM is already recorded, skipping connection initialization. Value: " +
utmData);
}
The approach is pretty simple, however the data seems to be wrong. So, does it seem that the implementation is somewhat incorrect? If not, why is the data received from Google Ads is wrong? Any help is appreciated, thank you very much.
Edit: Upon some testing, here is what I've found:
Works:
An API 19 real device (GM Discovery II Mini) and in between API 25-29 emulators with Play Store installed. Edit: UTM can also be fetched with API 23 and 24 Genymotion Emulators, where Play Store is installed.
Doesn't work:
An API 24 Android Studio emulator with latest Google Play Services and Play Store installed (device is also logged in to my account), and a real device (General Mobile 4G Dual, API 23) cannot query the UTM information. The code below lands on the case of InstallReferrerResponse.FEATURE_NOT_SUPPORTED. So I am almost sure that the install referrer client is bugged on some API levels.
Edit: Opened an issue to the Google: https://issuetracker.google.com/issues/149342702

As I don't know how you are processing the resonse, I can show you the way we did it in our implementation.
ReferrerDetails response = referrerClient.getInstallReferrer();
if (response == null) {
break;
}
String[] installReferrer = response.getInstallReferrer().split("&");
if (installReferrer.length >= 1) {
utmSource = installReferrer[0].split("=")[1];
}
if (installReferrer.length >= 2) {
utmMedium = installReferrer[1].split("=")[1];
}
Compare this snippet with yours and check if anything differs.

Android: Parse Server save Error 111: This is an invalid Polygon

I'm trying to save a GeoPolygon into my Parse server using an android app but I keep getting an:
error 111: this is not a valid polygon
this is my code:
//create the parse object
ParseObject obj = new ParseObject("SomeClass");
List<ParseGeoPoint> geoPoints = new ArrayList<ParseGeoPoint>();
geoPoints.add(new ParseGeoPoint(1.468074, 110.429638));
geoPoints.add(new ParseGeoPoint(1.468075, 110.429287));
geoPoints.add(new ParseGeoPoint(1.467376, 110.429681));
geoPoints.add(new ParseGeoPoint(1.467373, 110.429283));
ParsePolygon geoPolygon = new ParsePolygon(geoPoints);
obj.put("Boundaries", geoPolygon);
obj.saveInBackground(new SaveCallback() {
#Override
public void done(ParseException e) {
if (e == null) {
Toast.makeText(getContext(), "Geo Polygon save complete.", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getContext(), "Geo Polygon save failed. error: " + e.getMessage(), Toast.LENGTH_SHORT).show();
}
}
});
I followed the Docs for geopolygons here:
http://docs.parseplatform.org/android/guide/#parsepolygon
and somehow, even when I copy pasted the code provided in the docs, it doesnt work.
Any suggestions/ solutions are most welcomed.

I believe not many people may see this but I'll post my solution to this anyway.
The issue was solved after I updated the version of my Parse Server. I didn't note which version I updated the Parse Server from but my current Parse Server is now v2.7.1 .
Previous/ older version of Parse Server does not support geo-Polygons.

how to create Appoinment from Android MS CRM SDK?

i am creating appointment using below code give "500 Internal Server Error"
i added all fields check it
Appointment objappointment = Appointment.build()
.setSubject("Android sub")
.setDescription("dis from device")
.setRegardingObjectId(new EntityReference("account", UUID.fromString("0717b8e2-d00a-e611-8115-c4346bdd11d1")))
.setOwnerId(new EntityReference("systemuser", UUID.fromString("3edb272d-2da7-4c89-9350-2f4bd4e1762b")))
.setStateCode(new OptionSetValue(0))
.setNew_Latitude(23.7845)
.setNew_Longitude(73.6574)
.setNew_City("Surat")
.setActualStart(mDate.getTime())
.setActualEnd(mDate1.getTime())
.setNew_ZipPostalCode("380060")
.setNew_Street1("Street1")
.setNew_Street2("Street3")
.setNew_street3("Street3")
.setNew_StateProvince("Gujarayt")
.setNew_CountryRegion("India")
.setNew_Latitude(23.7845)
.setNew_Longitude(73.6574)
.setStatusCode(new OptionSetValue(0))
.setPriorityCode(new OptionSetValue(2));
try {
RestOrganizationServiceProxy restService = new RestOrganizationServiceProxy(mOrgService);
restService.Create(objappointment,new Callback<UUID>() {
#Override
public void success(UUID uuid, Response response) {
log("sucess", uuid.toString());
}
#Override
public void failure(RetrofitError error) {
displayError(error.toString());
log("error", error.toString());
}
});
}
catch(Exception ex) {
displayError(ex.getMessage());
log("msg",ex.toString());
}
another entity create successfully using above code just got error in "Appoinment"

Could you get more details of the exception? 500 could be any exception. At least you know the request hit the server and it's failing on the CRM server side. Maybe a plugin or similar is raising the exception.
I think you have to pass the objectid to whom the annotation will be linked to (Account, Contact, or whatever...)
Is that on-premise or online CRM? If OnPremise you could enable includeExceptionDetailInFaults property in the web.config to at least get more details of the exception....

Stripe android app connect to Node.js server

I'm working a project to integrate Stripe's payment service to my android app. I have the basic client code setup.
Card card = new Card("4242424242424242", 12, 2016, "123");
boolean validate = card.validateCard();
if (validate) {
try {
new Stripe(TEST_PUBLUSHABLE_KEY).createToken(card, new TokenCallback() {
#Override
public void onError(Exception e) {
System.out.println("ERROR");
}
#Override
public void onSuccess(Token token) {
System.out.println("SUCCESS");
}
});
} catch (AuthenticationException e) {
e.printStackTrace();
}
}
Now I need to setup a server, which I plan on using Node.js and Express. I followed their sample code on: https://stripe.com/docs/tutorials/charges
var express = require('express');
var bodyParser = require('body-parser');
var stripe = require('stripe')('sk_test_sGyqMsiFmf45xoZrDCy5ItcU'); // Test Secret Key
var app = express();
app.use(bodyParser());
app.post('/charge', function(req, res) {
var stripeToken = request.body.stripeToken;
var charge = stripe.charges.create({
amount: 1000, // amount in cents, again
currency: "cad",
card: stripeToken,
description: "payinguser#example.com"
},
function(err, charge) {
if (err && err.type === 'StripeCardError') {
console.log("The card has been declined");
}
});
});
app.use(express.static(__dirname + '/public'));
app.listen(3000);
I have never worked with servers, so I think I'm having trouble communicating between the android app and the server that is on my computer's localhost:3000.
According to Stripe's documentation, I need to have my server accept a HTTP POST call for the token, but I'm not quite sure how to do that.
Really appreciate your help.
Update #1:
Use Ultrahook to forward Stripe's POST to my localhost.
I use Node.js to setup my server, which receives all Stripe's requests and then get the information I need from the request body.
Still having trouble getting the onSuccess callback on Android to work, it always go to the onError callback.
Update #2:
Solved the onError callback error by printing the error message to console.
Permission denied (missing INTERNET permission?
Turns out I need to include this line to the AndroidManifest.xml:

Android - unable to use OAuth access token to retrieve Google Reader feeds

I need to obtain OAuth2 authentication token to pass it to the server so it can fetch list of Google Reader feeds for the user. Server is .NET - I have no access to it or to it's code but most likely it is using unofficial Reader API
I was able to use Android Account manager to obtain valid token for this purpose with the following code (notice that authTokenType="reader")
Account account = accounts[0];
manager.getAuthToken(account, "reader", null, this, new AccountManagerCallback<Bundle>() {
public void run(AccountManagerFuture<Bundle> future) {
try {
// If the user has authorized your application to use the tasks API
// a token is available.
String token = future.getResult().getString(AccountManager.KEY_AUTHTOKEN);
// Now you can send the token to API...
cacheManager.putString(GOOGLE_AUTH, token);
GoogleReaderManager.startAddFeedActivity(AddGoogleReaderSourcesActivity.this);
finish();
} catch (OperationCanceledException e) {
Log.e(TAG, "User cancelled", e);
finish();
} catch (Exception e) {
Log.e(TAG, "Failed to obtain Google reader API_KEY", e);
}
}
}, null);
The code above works fine when I send token to the server side .Net app: the app is able to retrieve the list of Reader feeds.
The problem is that this only works for "Google inside" devices. On Nook I have no such luck since there's no way that I was able to find to add Google account to the account manager. So I'm trying to it using OAuth 2 protocol as described here
It works fine as far as obtaining the token: User approves the app from the mobile page which returns the code token which then mobile app exchanges for the Auth token. However this token will not work with the server process. I have a feeling that perhaps I'm using the wrong scope in this URL:
https://accounts.google.com/o/oauth2/auth?response_type=code&scope=https://www.google.com/reader/api/0/subscription/list&redirect_uri=http://localhost&approval_prompt=force&state=/ok&client_id={apps.client.id}
Scopes that I did try in various combinations:
https://www.google.com/reader/api
https://www.google.com/reader/api/0
https://www.google.com/reader/api/0/subscription/list
https://www.google.com/reader/api+https://www.google.com/reader/atom
Here's example of JSON that is returned from get token POST
{"expires_in":3600,
"token_type":"Bearer",
"access_token":"ya29.AHES6ZSEvuUb6Bvd2DNoMnnN_UnfxirZmf_RQjn7LptFLfI",
"refresh_token":"1\/bUwa5MyOtP6VyWqaIEKgfPh08LNdawJ5Qxz6-qZrHg0"}
Am I messing up scope or token type? Not sure how to change a token type. Any other ideas?
P.S. Google account login page asks: Manage your data in Google Reader, that's why I suspect that the scope is wrong

I got it working for https://www.google.com/reader/api/0/subscription/list. So thought of sharing with you.
I have valid access_token:
This is what i tried to resolve it (partially) :
Google provides OAuth 2.o playgound; where they actually simulate all aspects of OAuth 2.0 as well as final API call to fetch data.
I found this very helpful as it clearly shows what is being sent to request.
Here is the URL : https://developers.google.com/oauthplayground/
Using this, i tweaked my api call below and it works :)
public static String getReaderContent(String accessToken){
String url = "https://www.google.com/reader/api/0/subscription/list" ;
HttpClient client = new HttpClient();
GetMethod method = new GetMethod(url);
String response="";
method.setRequestHeader("Authorization", "OAuth "+accessToken);
try {
int statusCode = client.executeMethod(method);
String response= method.getResponseBodyAsString();
System.out.println("response " + responseStr);
} catch (HttpException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return response;
}
So this works properly fine for getting subscription list; but have not been able to make it work for reader api which you have mentioned in your question.
Let me know if you have got way around google reader API.
