InAppBilling library - Android Market In-App Billing service

PS. I would like to modify this lib to add some functions like return string for support inapppayment

You should use the BillingSupported event for this.

About the error message, can you post the full stack trace?

 

[Erel]

You cannot show a Msgbox from a service.

 

[Erel]

This error message happened because of a msbox call inside the PurchaseStateChanged sub:

at anywheresoftware.b4a.keywords.Common.Msgbox(Common.java:383)
at com.kash.test.inappbillingservice._manager_purchasestatechange(inappbillingservice.java:105)

after some days testing. Libs works fine so far.

Just see that still using obfuscate option, service addon can be easily reversed and you just have to change whats happen on:

 If PurchaseState = Manager.PURCHASE_STATE_PURCHASED Then
      CallSub2(Main, "sdfsdfgdsfg", ExtraData)
   Else If PurchaseState = Manager.PURCHASE_STATE_CANCELED Then
      ToastMessageShow("canceled",False)
Else
ToastMessageShow("Not registered",False)
End If

So for example in this fast example created. If you change in smail CallSub2 instruction to the Else Line : ToastMessageShow("Not registered",False)

You would return the registered product and obfuscate doesnt works fine on other addons that doesnt are the main.

 

[Erel]

You can obfuscate all the strings by assigning them in Sub Process_Globals.

 

[KashMalaga]

You can obfuscate all the strings by assigning them in Sub Process_Globals.

I thinks that obfuscate strings here isnt be the solution if you can see whats function do when app gets registered from google answer

 

[Erel]

Obfuscation is not encryption. A determinant hacker with enough time will always be able to reverse engineer your code.

 

[KashMalaga]

Obfuscation is not encryption. A determinant hacker with enough time will always be able to reverse engineer your code.

Thanks for the information.

And obfuscation just split under hex the string, just example for someone that want to see how works:

Nomal string="hello my friend"

Obfuscated string on smali:

.array-data 0x1
        0x51t
        0x4at
        0x42t
        0xbct
        0x46t
        0x58t
        0x41t
        0x60t
        0xcet
    .end array-data

 

[Erel]

Why do you think that this is the way strings are obfuscated?

This is not correct.

Thank you for the in app billing service library.

I copied your tutorial code into a test program to test things out.
I used the android test purchase product IDs (ex. android.test.purchased)

At first, instead of naming my service module inappbillingservice, I named it BillSrv. When I compiled I got the error something like "Compile inappbillingservice_br not found". When I changed the name of the service module to inappbillingservice, the error went away.

After completing the android.test.purchased purchase and the "thank you for purchasing" message box is displayed, if I did not click okay for 20 seconds or so, I would get an error and "force close" MessageBox from android saying my test app has stopped.

When I look at the ExtraData field in the logs, it is displayed as "null" rather than the string "extra data" as specified in the RequestPayment call.

Thank you for the library. These are not biggies. The library seems to work great – now to test with products I create.

Barry.

 

[Erel]

Can you post the error message that appears in the unfiltered logs when the app crashes?

 

[canalrun]

Thanks for the reply.
I tried my test program on 2 devices a Samsung vibrant phone and an Acer A500 tablet. I press the "Buy" button in my app, it goes to Google for in app payments, in Google I press the "Accept & pay" button, it returns to my app and displays the "Thank you for purchasing" dialogue, instead of pressing the okay button I let it display. After about 20 seconds it displays the android "force close" message.

I have included unfiltered logs from the point I press the Google "accept" button for both devices below. I have also attached my zipped project.

Thanks,
Barry.

Are InApp purchases just like normal app purchases on Android Market (where the buyer can use the app on all his devices with the same Google account) or is the purchase restricted to only that device from which the inapp transaction was completed?

@canalrun, this error will only happen with the test keys. The test messages are not properly signed.
From my experience it is easier (and more reliable) to create some real low cost products and test them.

@Inman, managed transactions are not restricted to the device. When your program runs for the first time (only after installation) you should call RestoreTransactions to retrieve the previously purchased managed items.

Hello,
I am having some trouble using the In App Billing Library. I have a test application based on the tutorial code, I have uploaded unpublished, created a product, been able to make test purchases, and have them show up in my market account.

I am using un-managed products.

The problem comes in with the responses I am getting in PurchaseStateChange (PSC).

1) There is no way to cancel a purchase other than hitting the "back" button when in the Google portion of check out. But, hitting the back button does not generate the PSC "cancel" message. My app gets no kind of notification that the buyer canceled.

2) I made a purchase then canceled the purchase in the Google marketplace. I then made another purchase. From the second purchase I got a PSC of "your transaction was canceled". I looked on the Google Marketplace and there was a record showing a charge for the second purchase. The "transaction canceled" message showed a dialog box that came from somewhere – nowhere in my code. I think that "transaction canceled" message was referring to the first transaction which I had canceled in the Google marketplace. My app had no way of knowing that and had no notification of the valid purchase. I think this is what the "nonce" parameter is for – to identify the transaction related to the message. This parameter is not available in the library.

About 10 seconds after receiving the "transaction canceled" message, the app crashed with an Android force close.

I have seen complaints posted on the net about the variable length of time between a user clicking "Accept & Pay" in the Google checkout and the app receiving a PSC for the transaction.

How should I be coordinating my payment requests with the PSC's that come back from Google? My experiments with "extra data strings" come back as null in the PSC?

Any Suggestions?

Thanks,
Barry.

1) The "cancel" message means that the order was canceled. Not that the process was canceled in the middle. You should build your application in such a way that it only reacts to successful transactions.

2) You should use managed products if you want to handle refunds and cancels.

Thanks.

But, managed products have the fatal flaw that you could only buy one of something – this is only applicable to a certain class of products.

I don't want to handle cancels and refunds. When I canceled a previous transaction, in response to my next test purchase I received a MessageBox from somewhere (nowhere is it in my code) saying "transaction canceled". I have a feeling this was due to the previous purchase I had canceled in my market account, not my current purchase. There was no way to detect this message box popping up, there was no indication that it probably referred to a prior transaction, there was no indication in the app that the current transaction succeeded (I received no indication that I should credit that purchase. Although the charge showed up in my market account), and 10 seconds later the app crashed with a "force close".

As of now I am getting seemingly random messages and not getting reports of valid purchases.

How can I relate the PurchaseStateChange to the transaction for which it pertains.

Where does this message box that popped up for the cancel PSC come from?

Thanks,
Barry.

I guess that you mean a Toast message not a message box. It is displayed by the market service.

Lets start with the crash issue. Can you reproduce it? If you can please check the unfiltered logs and post the full stack trace.
