How to get a SKU price and display it in a TextView - android

I need to retrieve the price of my InApp Purchase and display it as a Title in my Card Layout.
This is how the card looks like, instead of "sku price", I need to have the actual price.
I have only this IAP so I shouldn't need an array or a list.
For implementing in App Billing I followed Android Developers - In App Billing Guide
So far I tried to write this inside my onQueryInventoryFinished() method, without any luck.
IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
#Override
public void onQueryInventoryFinished(IabResult result, Inventory inv) {
//have we been disposed of in the meantime? if so, quit
if (mHelper == null) return;
//is it a failure?
if(result.isFailure()) {
alert("Failed to query Inventory: " + result);
return;
}
String skuPrice = inv.getSkuDetails(SKU_PREMIUM).getPrice();
((TextView)findViewById(R.id.card_buy_title)).setText(skuPrice);
//do we have the premium upgrade?
Purchase premiumPurchase = inv.getPurchase(SKU_PREMIUM);
isPremium = (premiumPurchase != null && verifyDeveloperPayload(premiumPurchase));
}
};
As far as I was able to understand this thing I did should get the price of already purchased items. So maybe that is why it does not work.
Can anyone of you point me in the right direction?

In your mHelper setup you have to query all inventory by calling
mHelper.queryInventoryAsync(true, allSkus, null, mGotInventoryListener);
where allSkus is a list of all skues.
Check IabHelper.

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.

inapp purchase billing: QueryInventoryFinishedListener failed to find purchased item

I am testing my app with a managed item that I purchased.
Then I wanted to try to purchase the product with the same id again (with purchase flow). I therefore have cleared all play store data. After that I was able to purchase the product again.
Now I am wondering that if a user cleans the play store data accidentally (or looses his/her purchase for any other reason), will he/she then loose his/her purchase?
I didn't expect that behavior, because I thought that the purchase information is stored on google's remote servers.
Code example:
IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result, Inventory inventory) {
if (mHelper == null)
return;
if (result.isFailure()) {
// handle error here
return;
} else {
if (inventory.hasPurchase(PremiumUtils.SKU_AD_FREE)){
// User paid to remove the Ads - so hide 'em
hideAd();
}
else{
// Free user - annoy him with ads ;)
showAd();
}
return;
}
}
};

Implementing In-app Billing

I am currently working on in app purchase in my application, when it launches I have always the error code -1003 querying owned items response signature verification failed when I arrive in IabHelper.QueryInventoryFinishedListener method.
I currently uses the example version of Google "Trivial Drive", I guess my signature is correct because I get to buy much when I use android.app.purchassed ...
The key seems correct to me because when I click like to buy a product that tells me that the publisher can not buy the product which is normal in itself (If I put anything I have another error saying the product does not exist). For cons, I have the same error when I put the test product "android.test.purchasse" then I should be able to test with it.
I made a purchase with android.test.purchasse there and I can not reset if you have already succeeded I'm interested.

Have you ever been concerned? I see no way out for this bug help from you will be appreciated.
thank you
You need to create a test account, and put it in the playstore admin page.

Lost purchaseToken for In-App Billing Api

I was integrating Android In-App Billing api. but I lost the purchaseToken as there was a exception thrown somewhere. Now in API 3 I can't re-buy it without consuming the bought product. I can't consume it now as I don't have the purchaseToken? How to retrive it?
Or can I reset the purchase somehow??
You could get it by querying purchases.
Here is an example from Google: http://developer.android.com/google/play/billing/billing_integrate.html#billing-download
IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result, Inventory inventory) {
Log.d(TAG, "Query inventory finished.");
// Have we been disposed of in the meantime? If so, quit.
if (mHelper == null) return;
// Is it a failure?
if (result.isFailure()) {
complain("Failed to query inventory: " + result);
return;
}
Log.d(TAG, "Query inventory was successful.");
/*
* Check for items we own. Notice that for each purchase, we check
* the developer payload to see if it's correct! See
* verifyDeveloperPayload().
*/
// Do we have the premium upgrade?
Purchase premiumPurchase = inventory.getPurchase(SKU_PREMIUM);
....
//<- here you can consume your purchase
}

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
}
}
};
