NullPointerException when sendBillingRequest() function is called in GetPurchaseInformation class about inapp
<p>I'm in trouble by the following log.</p>

<p>I've tested like this.</p>

<ol>
<li>Purchased inapp item in my android application</li>
<li>Canceled the purchased item in Google Checkout web page.</li>
<li>At this time, <code>run()</code> function of <code>GetPurhcaseInformation</code> class is called in my running android application.</li>
<li>In this <code>run()</code> function, <code>mService.sendBillingRequest(request)</code> is called.</li>
<li>The following exception log is displayed immediately.</li>
</ol>

<p>But, Dungeons sample works very well.
My application uses some other broadcast receiver. 
I blocked these receiver, but the problem is occurred yet.</p>

<p>I found the link equals to my problem in web. But the bug wasn't be accepted and no answer.

<p>I'd like to know the code in MarketBillingService.java:661.</p>

<p>Any Ideas?</p>
