I implemented in-app billing in Android application, have like 6 product they are like coins the user will buy in order to buy items in my app.
The setup and the testing for in-app works perfectly I read all google documents and did what they said but my problem is that my product are shown in a listView i called the function mHelper.launchPurchaseFlow according to the position in the list in the activity but the items are always consumed or owned here is my code:
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 100 coins upgrade?
Purchase hundrendCoin = inventory.getPurchase(SKU_hundred);
if(hundrendCoin != null && verifyDeveloperPayload(hundrendCoin));
{
Log.d(TAG, "User have it ");
mHelper.consumeAsync(inventory.getPurchase(SKU_hundred), mConsumeFinishedListener);
}
// Do we have the 225 coins upgrade?
Purchase two_hundred_twenty_fiveCoin = inventory.getPurchase(SKU_two_hundred_twenty_five);
if(two_hundred_twenty_fiveCoin != null && verifyDeveloperPayload(two_hundred_twenty_fiveCoin));
{
Log.d(TAG, "User have it ");
mHelper.consumeAsync(inventory.getPurchase(SKU_two_hundred_twenty_five), mConsumeFinishedListener);
}
// Do we have the 350 coins upgrade?
Purchase three_hundred_fiftyCoin = inventory.getPurchase(SKU_three_hundred_fifty);
if(three_hundred_fiftyCoin != null && verifyDeveloperPayload(three_hundred_fiftyCoin));
{
Log.d(TAG, "User have it ");
mHelper.consumeAsync(inventory.getPurchase(SKU_three_hundred_fifty), mConsumeFinishedListener);
}
// Do we have the 475 coins upgrade?

* WARNING: Locally generating a random string when starting a purchase and

* case where the user purchases an item on one device and then uses your app on
* a different device, because on the other device you will not have access to the
* random string you originally generated.
*
* So a good developer payload has these characteristics:
*
* 1. If two different users purchase an item, the payload is different between them,
* so that one user's purchase can't be replayed to another user.
*
* 2. The payload must be such that you can verify it even when the app wasn't the
* one who initiated the purchase flow (so that items purchased by the user on
* one device work on other devices owned by the user).
*
* Using your own server to store and verify developer payloads across app
* installations is recommended.

Any help would be appreciated.
Bank class:
public class BankClass
{
public int itemID;
public int quantity;
public String price;
public BankClass(int itemID,int quantity,String price)
{
this.itemID=itemID;
this.quantity=quantity;
this.price=price;
}
}
Here is what i did with multi consuming .
List<Purchase> purchases = new ArrayList<>();
purchases.add(inventory.getPurchase(SKU_hundred));
purchases.add(inventory.getPurchase(SKU_two_hundred_twenty_five));
purchases.add(inventory.getPurchase(SKU_three_hundred_fifty));
purchases.add(inventory.getPurchase(SKU_four_hundred_seventy_five));
purchases.add(inventory.getPurchase(SKU_six_hundred));
purchases.add(inventory.getPurchase(SKU_one_thousand_two_hundred_twenty_five));
IabHelper.OnConsumeMultiFinishedListener onCusumeListner = new IabHelper.OnConsumeMultiFinishedListener()
{
@Override
public void onConsumeMultiFinished(List<Purchase> purchases, List<IabResult> results)
{
Log.d(TAG, "Consumption finished. Purchase: " + purchases + ", result: " + results);
// if we were disposed of in the meantime, quit.
if (mHelper == null) return;
// We know this is the "gas" sku because it's the only one we consume,
// so we don't check which sku was consumed. If you have more than one
// sku, you probably should check...
for(int i=0;i<results.size();i++)
{
if (results.get(i).isSuccess())
{
// successfully consumed, so we apply the effects of the item in our
// game world's logic, which in our case means filling the gas tank a bit
Log.d(TAG, "Consumption successful. Provisioning.");
} else {
complain("Error while consuming: " + results);
}
}
Log.d(TAG, "End consumption flow.");
}
};
mHelper.consumeAsync(purchases, onCusumeListner);
but in the result i don't know how to handle the success of the result for all items according to there position should i run a for loop for it or there is another way but still its crashing in all ways.
