I'm just looking through the code now, but I can't see where the service stops itself when the work is done (looking for a stopSelf()). After I finish() the app the BillingService continues to run. How are you stopping the service when using this library?

Many thanks, Richard

I am doing the following:

private static final String ANDROID_MARKET_ITEM = "android.test.purchased";
requestPurchase(ANDROID_MARKET_ITEM);

But onPurchaseExecuted is not called. Purchase Dialog is just closed.

What is wrong here? Also, if after that I check the database:

BillingDB bDB = new BillingDB(getApplicationContext());
Cursor purchases = bDB.queryPurchases();
Log.i(TAG, "Count: " + purchases.getCount());

I see that no records are added to the database.

Hi! Thanks a lot for this handy library.

I modified the source so that the raw signedData and signature strings are stored in the BillingDB. This way I can recover the transactions in my onPurchaseStateChanged callback through BillingController.getTransactions(this) and send to my server all the information needed to process the transaction and perform its verification.

It's a small modification, but I think most user will look after this feature.

This is a follow up to #58. Upgrade compatibility is guaranteed by the onUpgrade facility.

Important: Before merging this pull request, someone with good knowledge of this library should test if restoring transactions work

Hi there,

I added another method to be called in case the restoring of the transactions fails. It makes sense to know if it failed to display a message on an activity or a toast to let the user know that it failed (or handle it otherwise).

Best regards Andy

I have two activities - MainActivity extends ListActivity and Preferences extends AbstractBillingActivity.

If BillingController.isPurchased is called at MainActivity, then false is always returned. But if it is called at Preferences, then it returns correct value (true). Why it happens so?

There is no mention in documentation or tutorial on how to properly handle refunds. It is not clear what the action flow is and it is hard to test as well. Can somebody please add a How to handle refunds to the README file? Thanks.

One of my user got the following error:

What can be the reason?

I'm trying to use this library to implement in app billing to accept donations in my app (my app will sell unmanaged items called "donations"). When I call to requestPurchase(STORE_ITEM_ID); appears the Google Play screen showing my unmanaged item correctly, but after a second a popup is shown and says: "The item you requested is not available for purchase".... This is what I did:

1 - In my app: I created a new Activity that extends AbstractBillingActivity. I've overriden getObfuscationSalt method, it returns a byte array with 20 random digits. I've overriden getPublicKey method, it returns the public key I get in my developer console. I check if billing is supported using onBillingChecked, and finally when the user press the "donate" button I call requestPurchase if billing is supported.

2 - In my developer console: I uploaded a new app signed (but is not published, only uploaded). I created a new unmanaged item, and I activated it. Then I added a new gmail test account. Then I used a real android device to test it, I did a hard reset and l used my gmail test account. I installed my app (the same version I uploaded), and.... thats all

What I'm doing wrong? Can you help me please?

Hi,

thank you very much for the library, made the billing development a breeze.

This post is just a support request. The app I'm developing is VERY likely to be used on more than one device by user (because connect devices together) and through an in-app purchase it enables the full features.

Currently the app calls BillingController.restoreTransactions(context); only on the first run. But if (when) the user purchase the upgrade on a device 1, he won't see it on device 2 unless he uninstall/re-install the app.

So I ask, if I simply call it every single time the app loads, will there be any problem with the database that is storing the transaction or will just drop the DB and re-populate and that's it?

thanks.

i'm using the DungeonsRedux and trying the subscription service. I can buy a subscription through the app but after bought the subscription i return in the app and i can't see the bought subscription, the code: for (Transaction t : transactions) { if (t.purchaseState == PurchaseState.PURCHASED) { ownedItems.add(t.productId); } } ownedItems is empty and the method onPurchaseStateChanged is never called.

How i can fix this problem?

Thank you very much.

Hi,

First of all thak you for you nice library. It's really help me.

From time to time I've get this exeption from my users: java.lang.RuntimeException: Unable to start receiver net.robotmedia.billing.BillingReceiver: android.view.WindowManager$BadTokenException: Unable to add window -- token android.os.BinderProxy@41e718e8 is not valid; is your activity running?

I'm using AbstractBillingObserver for handling purchase process (not the activity version). As I understand sometimes for some reason Activity that I had put to Observer allready dead at the end of purchase. What is the proper way to handel this situation?

I'm using test ids. onPurchaseStateChange() gets called when user cancels the purchase but it's not called when when purchase is successful. I've followed step2 mentioned in the below link but its still not working

http://stackoverflow.com/questions/12844132/onpurchasestatechange-not-getting-called/12948238#12948238

I'm getting a DeadObjectException from BillingRequest line 294:

response = mService.sendBillingRequest(request);

I'm using the extending AbstractBillingActivity approach. The original request is:

requestPurchase("android.test.purchased")

I am using debug mode. Any ideas on how to track down the problem?

Hello. I have a issue: I bought the item in my application, and it was success. But in fact my function for purchase is never called. Every time I open my BillingActivity it shows me a window with text, that I have this item, and cannot buy it twice. As I see onPurchaseStateChanged is never called. And BillingController.isPurchased doesn't work in my case. I have read all topics with the same issues, but I don't understand, why it can be. Please, tell me, what I can do to fix this. And thank you for the library.

UPD: There is "W/BillingService(14265): Remote billing service crashed" In the logcat. Can my issue be because of this?

Hi,

In my billing activity I put :

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.billing);
    BillingController.registerObserver(mBillingObserver);
    BillingController.checkBillingSupported(this);
    BillingController.setSignatureValidator(this);
}

@Override
public void onDestroy() {
    super.onDestroy();
    BillingController.setSignatureValidator(null);
    BillingController.unregisterObserver(mBillingObserver);
}

I don't do anything within my "mBillingObserver"

I want to purchase an item (added in my google play account) :

BillingController.requestPurchase(this, purchaseId, false, null);

After my purchased, I can see a toast "Thanks for your purchased for the play store" and I'm called on my method :

@Override
public boolean validate(String signedData, String signature) {
    Log.i(TAG, "validate " + signedData);
    // when a purchased need to be checked, just return false if the server side check return false
    // TODO add the server side check here
    return false; // change it by the server side verification
}

in my logcat I can see "Billing(16214): Validation failed"

But the purchased wasn't canceled : I received an email from google to thanks me for my purchased.

Note : I don't call any other method of BillingController anywhere

Is it an error from me or from the billing library ?

Thanks
