In App Purchase : Two devices with same account not getting same purchased items

What I am trying?
Purchasing items in one android device having configured X email address. When I check in another device having the same email address configured. but items purchased on first device is not getting available in another device.
What I have tried?
I have tried using :
inappBillingService.getPurchases(InAppBuyActivity.INAPPVERSION,
getPackageName(), "inapp", null);
and also tried using :
IabHelper.QueryInventoryFinishedListener mGotInventoryListener
= new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result,
Inventory inventory) {
if (result.isFailure()) {
// handle error here
}
else {
// Not getting same purchased on both devices
}
}
};
I am generating signed apk having the same version name and version code as of playstore version.

I have tested the app using two devices. It takes sometime to reflect the purchases.
If i delete the app and reinstall it as a fresh then new purchased items are there. But, if i purchase one item and check it on second device at same time its not reflected there.
App shows items already purchased in second device when user try to purchase it. But, its not available in inappBillingService.getPurchases and IabHelper.QueryInventory.

The In-app Billing Version 3 API makes it easier for you to integrate In-app Billing into your applications.The features in this version include improved synchronous purchase flow, APIs to let you easily track ownership of consumable goods, and local caching of in-app purchase data.
1. Check in your code, if you used consumable or not
if you used consumable, user can purchase product multiple time, google store only one time purchase detail and again getting blank response, so remove consumable related code from your app.
2. Check user already purchased item or not using below code
private IInAppBillingService mService = null;
//onCreare
try {
Intent serviceIntent = new Intent("com.android.vending.billing.InAppBillingService.BIND");
serviceIntent.setPackage("com.android.vending");
bindService(serviceIntent, mServiceConn, Context.BIND_AUTO_CREATE);
// bindService(new Intent("com.android.vending.billing.InAppBillingService.BIND"), mServiceConn, Context.BIND_AUTO_CREATE);
} catch (Exception e) {
e.printStackTrace();
}
// Method
ServiceConnection mServiceConn = new ServiceConnection() {
#Override
public void onServiceConnected(ComponentName name, IBinder service) {
mService = IInAppBillingService.Stub.asInterface(service);
Log.d("TEST", "mService ready to go!");
checkownedItems();
}
#Override
public void onServiceDisconnected(ComponentName name) {
mService = null;
}
};
private void checkownedItems() {
try {
Bundle ownedItems = mService.getPurchases(3, getPackageName(), "inapp", null);
if (ownedItems.getInt("RESPONSE_CODE") == 0) {
ArrayList<String> ownedSkus = ownedItems.getStringArrayList("INAPP_PURCHASE_ITEM_LIST");
ArrayList<String> purchaseDataList = ownedItems.getStringArrayList("INAPP_PURCHASE_DATA_LIST");
if (purchaseDataList.size() > 0) {
// Item already Purchased....
// Manage your in-app view
}else{
// Item not purchased
}
}
} catch (RemoteException e) {
e.printStackTrace();
}
}
Used above logic before purchase item, if item not purchase then call in-app getPurchases() otherwise hide or manage in-app view.

Android In-App Billing, missing purchases

I am using Google's In-App Billing for my Android app.
I used the IabHelper class from Google's how to, as their billing seems extremely complicated.
My issue is I want to know if the purchase is successful or not. I think I'm following the process correctly, but in my logs I see a lot of users that get the upgrade, but whose purchase never shows up in my Google Play payments account. (i.e. they get the upgrade for free).
I'm logging the GP order ids, sometimes its a number like,
GPA.1234-5678-9123-1234
But sometimes its like,
1234567891234.1234567891234
Normally I think its the non GPA orders that don't get charged.
Also I think you can put an order through, then cancel it, and still get the upgrade?
How do you ensure the user really paid?
Code:
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
public void onIabPurchaseFinished(IabResult result, final Purchase purchase) {
if (result.isFailure()) {
showMessage("Google Billing Purchase Error");
return;
} else if (purchase.getSku().equals(sku)) {
IabHelper.QueryInventoryFinishedListener mReceivedInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result, Inventory inventory) {
if (result.isFailure()) {
showMessage("Google Billing Error");
return;
} else {
if (inventory.hasPurchase(sku)) {
showMessage("Thank you for upgrading");
grantUpgrade();
// ** This line gets call, but no payment occurs.
}
}
}
};
mHelper.queryInventoryAsync(mReceivedInventoryListener);
}
}
};
mHelper.launchPurchaseFlow(this, sku, 10001, mPurchaseFinishedListener, "");
*** updated to check "inventory.hasPurchase(sku)" but still see users who get the upgrade but don't pay.
** maybe the users are using Freedom hack? Anyway to prevent this?

if (result.isFailure()) {
//If the user aborts or any other problems it will jump here
}
else {
//The user purchased some item, check out which it is
mIsPremium = inventory.hasPurchase(SKU_ANY_ITEM);
}
So concerning your question, this code already verify whether the user really purchased the item !

Purchase premiumPurchase = inventory.getPurchase(SKU);
boolean mIsPremium = (premiumPurchase != null
&& verifyDeveloperPayload(premiumPurchase));
if(mIsPremium){
...
}

The Google Play Store keeps track of purchases for you, so you shouldn't assume that just because a purchase was successful, the item will stay purchased. It's possible for a user to get a refund for a purchase. For this reason, you need to query the user's inventory every time you launch and adjust your grants appropriately. You would need to do this check anyways in order to support users that expect to have the grant when they switch to a new device or uninstall/reinstall the app.

Android in app purchase hanging the application

I have an Android app that launches the purchase flow from a dialog within a Fragment.
The purchase flow is launched like:
config.getIabHelper().launchPurchaseFlow(
faActivity,
sku,
Constantes.SOLICITUD_COMPRA,
faActivity.mPurchaseFinishedListener,
purchaseIdentifier);
Where:
config.getIabHelper() returns an instance of the IabHelper class as implemented in the google documentation (the same used in the trivialgame example)
faActivity is the parent activity of the fragment
Constantes.SOLICITUD_COMPRA is a positive integer
mPurchaseFinishedListener is the listener, which is implemented in the parent activity.
So the current flow should work like:
Make a purchase.
Acknowledge that the purchase was bought.
Update the UI so that it enables the user to use the purchased item rather than to buy it.
However it works like:
Make a purchase.
The application freezes and stops.
When the application is relaunched, the inventory is queried and the UI gets updated.
It seems like mPurchasedListener is never called.
To make it more weird, everything seems to work fine with test responses. I am testing the app in alpha with real responses and that is where the trouble appears.
Any ideas?

i've had this issue before my self and there are multiple things that could be causing this issue.
Firstly, please make sure that you've done the following for aplha stage testing and that you've added all the required permissions and aidl files.
1) Are you using a version of the app you've put on your device through android studio? If so, this could be your issue. Usually you'll receive a message notifying you that the version of the app you're using isn't compatible with in-app purchases. Alpha stage apps are actually downloaded from the google play store. You should have set up a google group that has access to a specific link that will allow you to open the google play store and download your alpha stage app.
2) Are you connected to the internet? Obviously launching a purchase flow with a real SKU will require an internet connection to the google play servers.
3) Did you set up this in app product up as a managed product? For simplicity, i highly recommend doing so.
if you've correctly set up everything as I mentioned above and are still having a problem, then likely it's an issue with how you setup and attempt to use your purchase flow.
Here's the steps i took to launching a purchase flow from within a fragment
Instead of setting up the IAB Helper in the fragment, set it up in the faActivity Class. We will then call the purchase flow method within the faActivity class from within the fragment in which you're viewing via Dialog Box.
This is how i set up in app purchases :
faActivity.java
IabHelper mHelper;
In the oncreate method :
String base64EncodedPublicKey = "your in app purchase key";
mHelper = new IabHelper(this, base64EncodedPublicKey);
mHelper.startSetup(new
IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result)
{}});
Add these methods as well :
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent data)
{
if (!mHelper.handleActivityResult(requestCode,
resultCode, data)) {
super.onActivityResult(requestCode, resultCode, data);
}
}
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener
= new IabHelper.OnIabPurchaseFinishedListener() {
public void onIabPurchaseFinished(IabResult result,
Purchase purchase)
{
if (result.isFailure()) {
return;
}
else if (purchase.getSku().equals(ITEM_SKU)) {
consumeItem();
}
}
};
public void consumeItem() {
mHelper.queryInventoryAsync(mReceivedInventoryListener);
}
IabHelper.QueryInventoryFinishedListener mReceivedInventoryListener
= new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result,
Inventory inventory) {
if (result.isFailure()) {
// Handle failure
} else {
mHelper.consumeAsync(inventory.getPurchase(ITEM_SKU),
mConsumeFinishedListener);
}
}
};
IabHelper.OnConsumeFinishedListener mConsumeFinishedListener =
new IabHelper.OnConsumeFinishedListener() {
public void onConsumeFinished(Purchase purchase,
IabResult result) {
/*The purchase was successfully consumed, now update the
//ui/award the user with their purchase (I suggest storing the fact that
they're premium or whatever within the shared prefrences of your app)*/
}};
String ITEM_SKU = "";
//Launching the purchase Flow
public void makeThePurchase() {
//Assign the SKU Name of your managed product
ITEM_SKU="premiumMembership";
mHelper.launchPurchaseFlow(this, ITEM_SKU, 10000,
mPurchaseFinishedListener, "mypurchasetoken");
}
Now in your fragment, use this code to show a dialogBox asking the user if they wish to purchase the product and launch the purchase flow if they wish to do so
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
builder.setView(inflater.inflate(R.layout.dialog_signin, null))
.setPositiveButton("Purchase", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
((faActivity)getActivity()).makeThePurchase();
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.dismiss();
}
});
builder.setTitle("Purchase");
builder.setMessage("Purchase premium membership?");
builder.create().show();
And that is how i managed to launch a purchase flow from within a fragment. I'm sure there is a better way to do so, but when setting up the purchase flow from within the fragment, i always recieved issues as well when trying to launch a purchase.
Hopefully this solved your issue!
Good Luck!!! :)
NOTE: The code i've listed above is setup to consume the purchase (meaning that the fact that they own it won't show up when querying the inventory) Like i said above although, if you're not concerned about the users having to repurchase their items/premium purchases in the occurance of them getting a new device or uninstalling your app, then just keep track of what they've purchased and consumed within the shared preferences by calling this code below from within the onConsumePurchasedFinished listener :
SharedPreferences pref = getActivity().getApplicationContext().getSharedPreferences("MyPref", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = pref.edit();
editor.putBoolean("hasBoughtPremium",true);
editor.apply();
Then when reloading the app, check to see if they own the premium item :
SharedPreferences pref = getActivity().getApplicationContext().getSharedPreferences("MyPref", Context.MODE_PRIVATE);
Boolean isPremium = pref.getBoolean("hasBoughtPremium",false);

Android inapp billing responseList is empty

I have defined some in app products in my app. I've uploaded the apk to the Google Play and added the inapp purchase products on the Google play.
I've got my ServiceConnection defined as followed:
ServiceConnection mServiceConn = new ServiceConnection() {
#Override
public void onServiceDisconnected(ComponentName name) {
mService = null;
}
#Override
public void onServiceConnected(ComponentName name, IBinder service) {
mService = IInAppBillingService.Stub.asInterface(service);
connect();
}
};
The onServiceConnected function is called, the bindService returns true.
Next is the connect function.
public void connect() {
new Thread(new Runnable() {
public void run() {
try {
// Purchase type is "inapp", as required by API v3
Bundle skuDetails = mService.getSkuDetails(3, PACKET, "inapp", querySkus);
}
int response = skuDetails.getInt("RESPONSE_CODE");
Log.e("IAP connect", response + "");
if (response == 0) {
ArrayList<String> responseList = skuDetails.getStringArrayList("DETAILS_LIST");
Log.e("size list", responseList.size()+"");
...
}
}
} catch (RemoteException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
}
}).start();
}
PACKET here is set to the getPackageName().
The response code is 0 but the Log prints that the size of the list is 0. I have no idea why the list is empty, as I have entered 5 items in total to the Google Play and each of them are active. I have waited 2 days now and tested with three devices, but still no items get through.
I pretty much tried everything I can think of so any suggestions are welcome.

You need to publish your application to Beta/Alpha to access inapp billing functionality.
It has recenty changed, but they did not announce it:)
http://developer.android.com/google/play/billing/billing_testing.html#draft_apps
It is worth to mention that you don't have to upload every new build to be able to test it. Just use the same versionCode and versionName, and it will work if the app is published.

Your Code looks ok.
Make sure you query the right SKUs. The single items in querySkus must match exactly the id of the in app product.
Second make sure to query the correct type if items. If you configured "in app products" as a car to buy in the developer console, use "inapp" as you did. If you have subscriptions, use "subs" as type of your query against Google Play.
Hope this helps.

I had the problem on an old device. Deleting Play Services app data fixed the problem.
So we simply need to get ready for the bad reviews...

I had the same problem, the fix was setting my subscription status to "active".
After a few minutes it finally worked.

Android In-App-Billing refund/cancel takes long

)
I'm trying to implement in-app-billing within my app. In the Google Play Developer Console I declared a managed item. Buying this item works really fine. But now, when I refund or cancel the purchase in the google wallet merchant center, my app takes very long (more days) to recognize that the item is not longer owned.
I've already read lots of other articles about this problem and think one logical explanation is that the purchase is saved in the cache of the Google Play Store. Although I know that this question has asked often before, I ask here again:
Is it possible to clear the cache or does anyone know how to tell my app, when the purchase is not longer owned?
I'm thankful for any hint, that helps me to solve this problem :D
In addition, my code where I ask, if the item is purchased. I'm using in-app-billing v3.
public boolean hasUserBoughtItem() {
try {
Bundle ownedItems = mService.getPurchases(mUsedAPI, mContext.getPackageName(),
mPurchaseType, null);
int response = ownedItems.getInt("RESPONSE_CODE");
if(response == 0) {
ArrayList<String> ownedSkus = ownedItems.getStringArrayList("INAPP_PURCHASE_ITEM_LIST");
if(!ownedSkus.isEmpty()) {
for(String sku : ownedSkus) {
if(sku.equals(Constants.ITEM_ID_ALL_RECIPES)) {
return true;
}
}
}
return false;
}
} catch(Exception e) {
e.printStackTrace();
}
return false;
}

The IAP purchase inventory isn't cached by the Play Store at all and should be queried regularly in your activities. It should only take approximately 15-30mins for order cancellations to propagate.
Are you using the IABHelper as per the sample app to connect to Google Play?
IabHelper.QueryInventoryFinishedListener mGotInventoryListener
= new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result,
Inventory inventory) {
if (result.isFailure()) {
// handle error here
}
else {
// does the user have the premium upgrade?
mIsPremium = inventory.hasPurchase(SKU_PREMIUM);
// update UI accordingly
}
}
};
