Android in-app billing: Can't start async operation because another async operation (is in progress)

Question

I am using the IabHelper utility classes, as recommended by Google\'s tutorial, and I\'m being hit hard by this error. Apparently IabHelper can not

Answer 1

I had the same issue and the problem was that I didn't implement the method onActivityResult.

@Override
protected void onActivityResult(int requestCode,
            int resultCode,
            Intent data)
{
    try
    {
        if (billingHelper == null)
        {
            return;
        } else if (!billingHelper.handleActivityResult(requestCode, resultCode, data))
        {
            super.onActivityResult(requestCode, resultCode, data);
        }
    } catch (Exception exception)
    {
        super.onActivityResult(requestCode, resultCode, data);
    }
}

Answer 2

Just check for the onActivityResult requestCode on the activity and if it matches the PURCHASE_REQUEST_CODE you used on the purchase just pass it to the fragment.

When you add or replace the fragment in the FragmentTransaction just set a tag:

fTransaction.replace(R.id.content_fragment, fragment, fragment.getClass().getName());

Then on your activity's onActivityResult

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == PurchaseFragment.PURCHASE_REQUEST_CODE) {
        PurchaseFragment fragment = getSuportFragmentManager().findFragmentByTag(PurchaseFragment.class.getNAme());
        if(fragment != null) {
            fragment.onActivityResult(requestCode, resultCode, data);
        }
    }
}

Answer 3

if you code in fragment then you this code in IabHelper.java

void flagStartAsync(String operation) {
    if (mAsyncInProgress) {
        flagEndAsync();
    }
    if (mAsyncInProgress) throw new IllegalStateException("Can't start async operation (" +
            operation + ") because another async operation(" + mAsyncOperation + ") is in progress.");
    mAsyncOperation = operation;
    mAsyncInProgress = true;
    logDebug("Starting async operation: " + operation);
}

Answer 4

Yes, i am also facing this issue but i resolved this but i resolved using

IabHelper mHelpermHelper = new IabHelper(inappActivity, base64EncodedPublicKey);
  mHelper.flagEndAsync();

The above method stop all the flags. Its work for me must check

Answer 5

Make sure that you call the IabHelper's handleActivityResult in the Activity's onActivityResult, and NOT in the Fragment's onActivityResult.

The following code snippet is from TrivialDrive's MainActivity:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.d(TAG, "onActivityResult(" + requestCode + "," + resultCode + "," + data);
    if (mHelper == null) return;

    // 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.");
    }
}

Update:

• There is now a In-app Billing Version 3 API (what was the version in 2013?)
• The code sample has moved to Github. Snippet above edited to reflect current sample, but is logically the same as before.

Answer 6

A simple trick that did it for me was to create a method in IabHelper:

public Boolean getAsyncInProgress() {
    return mAsyncInProgress;
}

and then in your code, just check:

if (!mHelper.getAsyncInProgress())
    //launch purchase
else
    Log.d(TAG, "Async in progress already..)
