onIabPurchaseFinished never called.

Question

I've been trying to set up in-app billing for my first app, and have been using the android.test.purchased sku. The purchase come through, and I manage to get the SKU into my inventory, but, as the title says, onIabPurchaseFinished, is never called.

I think it may have something to do with this Log: "Couldn't save which view has focus because the focused view com.android.internal.policy.impl.PhoneWindow$DecorView@406743d0 has no id". That pops up, right before going of to Google Play. I'm not really sure what that means though...

Launching purchase:

mHelper.launchPurchaseFlow(this, sku, 10001, mPurchaseFinishedListener, ""); 

And the Listener:

IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {      @Override     public void onIabPurchaseFinished(IabResult result, Purchase info) {         System.out.println("Purchase Finish heard something");          if (result.isFailure()) {              Log.d(TAG, "Error purchasing: " + result);              return;         } else{                 Log.d(TAG,"Success!");              }       } }; 

Answer 1

Try adding this to the Activity that calls mHelper.launchPurchaseFlow(..):

    @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) {     Log.d(TAG, "onActivityResult(" + requestCode + "," + resultCode + "," + data);      // Pass on the activity result to the helper for handling     if (!mHelper.handleActivityResult(requestCode, resultCode, data)) {         // not handled, so handle it ourselves (here's where you'd         // perform any handling of activity results not related to in-app         // billing...         super.onActivityResult(requestCode, resultCode, data);     }     else {         Log.d(TAG, "onActivityResult handled by IABUtil.");     } } 

Answer 2

i just found out another important thing: the requestCode that is used to launch the purchase flow has to be >= 0!

i used "new Random().nextInt()" to generate a random requestCode, and sometimes it worked, sometimes it didn't. now i found out in the following documentation, that the requestCode should not be a negative number:
