I am pulling my hair out! At one point in the last week, I had this working.
I have an Android app that I am trying to add in-ap billing to. I followed the sample TrivialDrive, and my code worked a few times. Now it doesn't.
I am creating a simple trivia game that has a number of free questions, and the option to upgrade to get more questions. When the user completes the list of free questions, they are taken to a "Game Over" screen where they can erase their answers and start again, or upgrade.
When I click the "Upgrade" button, I can make a successful purchase, but as soon as the Google "Payment Successful" dialog goes away, my activity is destroyed and I am sent back to my main activity.
When I try to go back and do my purchase again, my code catches the error ("You already own this item") and handles it appropriately. My code explains to the user that they already own the upgrade, and allows them to click a button to continue playing. So it looks like the OnIabPurchaseFinishedListener is firing at this point.
I have updated the Google helper code with the latest files.
Any help or suggestions as to where to look for answers is much appreciated.
Thanks.
This is the relevant code for my activity:
public class GameOverActivity extends BaseActivity

butPlay.setVisibility(View.INVISIBLE);
PrepareIAB();
