Android In-App Billing v3: “Can't perform operation: queryInventory”

Question

I have setup In-App Billing for the first time using the new v3 API. It is working correctly on my devices but I have received a lot of error reports from other users.

As @Martin explained, there was a bug in the Google In-App Billing example which caused this.

However, after fixing it, I was still receiving some errors in internal calls (queryInventory inside the thread created in queryInventoryAsync in some rare cases reports that the helper is not setup). I have solved this by adding an additional catch in that case:

try {
    inv = queryInventory(querySkuDetails, moreSkus);
}
catch (IabException ex) {
    result = ex.getResult();
}
catch(IllegalStateException ex){ //ADDED THIS CATCH
    result = new IabResult(BILLING_RESPONSE_RESULT_ERROR, "Helper is not setup.");
}

I also got a crash on mHelper.dispose() which I fixed in a similar way:

try{
    if (mContext != null) mContext.unbindService(mServiceConn);
}
catch(IllegalArgumentException ex){ //ADDED THIS CATCH
    //IGNORE IT - somehow, the service was already unregistered
}

Of course, instead of ignoring these errors you can silently log them to ACRA, for example :)

Thanks for all your comments.
