Android in-app billing: custom sku purchase gives “Error - item not found”

Question

I\'m trying to test in-app billing using my own sku/product ID \"upgrade_to_premium\". As I have seen recommended here, I am using the Dungeons sample app. I\'ve added a \"n

You should note there are some very misleading errors and dialogs displayed in the demo Dungeons.java:

--

If you are getting "Error: This version of the application is not configured for Market billing."

You must installed the RELEASE apk to your android DEVICE not emulator meaning:

• Exporting your APK and signing it

• Deleting any previous installation of your app on your device (even debug / developer versions!)

• Side loading the APK to your device, installing it, and running it.

• This also means debugging your released app is probably going to be without your debugger attached. If your debugger is attached, do tell me how!

If you are getting "Error: Item not found", there's a decent chance there is nothing wrong.

Dungeons.java actually has a bug in it. Let me explain:

/**
 * Called when a button is pressed.
 */
@Override
public void onClick(View v) {
    if (v == mBuyButton) {
        if (Consts.DEBUG) {
            Log.d(TAG, "buying: " + mItemName + " sku: " + mSku);
        }

        if (mManagedType != Managed.SUBSCRIPTION &&
                 // ** The following line is bug when returns !true which is false, and then makes the if statement false
                !mBillingService.requestPurchase(mSku, Consts.ITEM_TYPE_INAPP, mPayloadContents)) { 
            showDialog(DIALOG_BILLING_NOT_SUPPORTED_ID);

            // ** Which then ends up running this else if, meaning it will try to purchase a subscription
        } else if (!mBillingService.requestPurchase(mSku, Consts.ITEM_TYPE_SUBSCRIPTION, mPayloadContents)) {
            // Note: mManagedType == Managed.SUBSCRIPTION
            showDialog(DIALOG_SUBSCRIPTIONS_NOT_SUPPORTED_ID);
        }
    } else if (v == mEditPayloadButton) {
        showPayloadEditDialog();
    } else if (v == mEditSubscriptionsButton) {
        editSubscriptions();
    }
}

Rather it should be written like this:

/**
 * Called when a button is pressed.
 */
@Override
public void onClick(View v) {
    if (v == mBuyButton) {
        if (Consts.DEBUG) {
            Log.d(TAG, "buying: " + mItemName + " sku: " + mSku);
        }

        // We need this statement to evaluate to true on a Non-Subscription such as a Managed or Unmanaged Purchase
        if (mManagedType != Managed.SUBSCRIPTION) { 

                // If the following errors out, show an error dialog.  However, it should not make the previous if statement false
                if( !mBillingService.requestPurchase(mSku, Consts.ITEM_TYPE_INAPP, mPayloadContents)) { 
                    showDialog(DIALOG_BILLING_NOT_SUPPORTED_ID);
                }

        } 

         // This if statement gets run accidentally without the bug fix, thus trying to buy your "SKU" as a "subscription", which is totally wrong!
        else if (!mBillingService.requestPurchase(mSku, Consts.ITEM_TYPE_SUBSCRIPTION, mPayloadContents)) { 
            // Note: mManagedType == Managed.SUBSCRIPTION
            showDialog(DIALOG_SUBSCRIPTIONS_NOT_SUPPORTED_ID);
        }
    } else if (v == mEditPayloadButton) {
        showPayloadEditDialog();
    } else if (v == mEditSubscriptionsButton) {
        editSubscriptions();
    }
}
