in-app-billing

When someone buys an in-app product in an Android app and the owner cancels the payment in Google Checkout, so he gets refunded - does the user still keep the item? (managed type of in-app product). I know that a refund is not possible but I would like to cancel orders from users that already donated money, so they can have the in-app product for free. It's up to you to manage refunded items. You have more infos here : In-app billing does not allow users to send a refund request to Android Market. Refunds for in-app purchases must be directed to you (the application developer). You can then

I have implemented a test app with Android's In-App Billing. I have filled in my Public Key in the Security.java file. Everything works, but when I submit the payment, the app crashes. I receive an error in LogCat that says "Signature Verification Failed", which corresponds to this bit of code: if (!sig.verify(Base64.decode(signature))) { Log.e(TAG, "Signature verification failed."); return false; } If I change that bit to return true instead of return false, then everything works properly - I can submit payment and safely return to the app - but I am assuming that something else is wrong,

I'm implementing In App Billing for the first time and I'm testing my first purchases using the static SKU ids. It worked very well the first time. I called mHelper.launchPurchaseFlow(...) and completed the test purchase. My activity received the onActivityResult callback and I made sure to process it with mHelper.handleActivityResult(...) . Everything was great. @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { // Pass on the activity result to the helper for handling log("onActivityResult"); if (!this.mHelper.handleActivityResult(requestCode,

I've followed the training about "In-App Billing v3" of Google. I get to do a buy of a item but I've a problem. https://developer.android.com/training/in-app-billing/index.html I've canceled and refunded the buy but the app detect the buy as true. I can't continue testing my app because always I detect as purchased the item. The only error that I've found in logCat is the next: [3687] InAppBillingService.logResponseBundle: Bundle does not contain a response code Appears after launching mHelper.queryInventoryAsync(mGotInventoryListener). Any idea? p.s. - this suggests it just takes time for the

I'm developing an android application and I would like some functionality of the application is not free. I have thought to use in-app Billing Version 3 API, so I have defined an "In-App Product" in the developer console. After reading the documentation, I know that when I start the purchase flow I should pass in a string token that helps the application to uniquely identify the user who made the purchase. But how could I obtain a string token that identify the user? Thanks you can use developer payload to identify user and for the security. there are two way to generate developer payload
