IabHelper PurchaseFinishedListener

问题

If I send a purchase intent via the standard

String mySku = "android.test.purchased";

mHelper.launchPurchaseFlow(this, mySku, 10001, mPurchaseFinishedListener);

I am able to purchase the item and it will store and I can query the item and that works fine too. The only thing that doesn't work is is the PurchaseFinishedListener. I've got it coded pretty much identical to the sample app however it doesn't seem to get called at all.

12-12 01:40:47.248: D/IabHelper(23502): Calling getPurchases with continuation token: null
12-12 01:40:50.116: D/IabHelper(23502): Starting async operation: launchPurchaseFlow

These are the last two methods that get called and after that when I finish the purchase it doesn't call the purchasefinishedlistener

IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new OnIabPurchaseFinishedListener() {

    @Override
    public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
        Log.d(TAG, "Purchase finished: " + result + ", purchase: "
                + purchase);
        if (result.isFailure()) {
            complain("Error purchasing: " + result);
            // setWaitScreen(false);
            return;
        }

        if (purchase.getSku().equals(mySku)) {
            Log.d(TAG, "mySku is being consumed.");
            mHelper.consumeAsync(purchase, mConsumeFinishedListener);
        }
        Log.d(TAG, "Purchase successful.");
        new AsyncQuestionsActivity().doInBackground();
    }
};

Nothing from the log to the end works. Is there anything that I'm just somehow missing?

回答1:

I found out how to fix it. Implement handleActivityResult in onActivityResult. It's needed to create a bridge between the listener and the launched purchase flow.

Given below is the code I used:

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        Log.d(TAG, "onActivityResult(" + requestCode + "," + resultCode + ","
                + data);

        // Pass on the activity result to the helper for handling
        if (!mHelper.handleActivityResult(requestCode, resultCode, data)) {
            super.onActivityResult(requestCode, resultCode, data);
        } else {
            Log.d(TAG, "onActivityResult handled by IABUtil.");
        }
    }

AndroidPenguin, I'm running into the same issue as you, but I have the activityresult correctly set and yet my purchasefinishedlistener does not execute.

Here is my onActivityResult

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (SettingsManager.getBooleanSetting(rootId, "inapppurchase", false)){
        Log.d(TAG, "take care of activity result with billing helper");
        if (!mBillingService.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.");
        }
    }
    else
        super.onActivityResult(requestCode, resultCode, data);
}

In my case, it is working try like this, wait until that google play dialog close itself.Then, the listener will get called

回答4:

For those of you who had the same issue I was experiencing...

I just made my member variable IabHelper static, and that fixed the issue.

I already had added AndroidPenguin's code, and was still getting crashes from a null IabHelper, after I had purchased an item(so onActivityResult never had a chance to call handleActivityResult because mHelper was null).
