android – onIabPurchaseFinished never called.

Questions:

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 [email protected] 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!");
             }


    }
};
How to&Answers:

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:

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:

Answer:

I had the same issue and the onActivityResult was not called either.

Inspired from @Ghulam’s answer I realized that the activity onActivityResult doesn’t call the fragment’s onActivityResult automatically so I had to do it
manually.

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if(mCurrentFragment!= null){
            mCurrentFragment.onActivityResult(requestCode, resultCode, data);
        }
    }

Answer:

You need to call protected void onActivityResult(); In your parent Activity instead of MainActivity(Trivial Drive) where from you are calling your MainActivity that is Trivial Drive Activity.

you will receive resultcode values -1 if purchase successful otherwise 0.

Answer:

I was facing the same issue and the accepted solution was already implemented but couldn’t tell what was causing this. Moving to the new Google Play Billing Library 1.0 (released on 19 September 2017) fixed the issue for me!

I hope following links will help someone who would like to implement the new library:
