POLicenseChecker checkAccess leaks ServiceConnection

Body
copied!<p>I am receiving this exception in LogCat every time I press the <code>Back</code> button in my app:</p> <blockquote> <p>Activity has leaked ServiceConnection com.android.vending.licensing.LicenseChecker@471cc039 that was originally bound here</p> </blockquote> <p>The code responsible for this leak in <code>onCreate()</code> is:</p> <pre><code>mLicenseCheckerCallback = new MyLicenseCheckerCallback(); mChecker.checkAccess(mLicenseCheckerCallback); </code></pre> <p>How do I get rid of this leak?</p> <p>I tried not assigning MyLicenseCheckerCallback to a member, thinking perhaps when the activity goes <code>onPause()</code> the reference to the callback is responsible for the leak:</p> <pre><code>mChecker.checkAccess(new MyLicenseCheckerCallback()); </code></pre> <p>But that didn't get rid of the leak.</p> <p><strong>Update:</strong> Thanks to @zapl's comment below, I looked at Google's <code>LicenseChecker.java</code>:</p> <pre><code>/** Unbinds service if necessary and removes reference to it. */ private void cleanupService() { if (mService != null) { try { mContext.unbindService(this); } catch (IllegalArgumentException e) { // Somehow we've already been unbound. This is a non-fatal error. Log.e(TAG, "Unable to unbind from licensing service (already unbound)"); } mService = null; } } </code></pre> <p>At first I thought that I may be neglecting to call it, but I double-checked and I <em>am</em> calling <code>mChecker.onDestroy();</code> in my activity's <code>onDestroy()</code>.</p> <p>I also checked <code>onDestroy()</code> in <code>LicenseChecker.java</code> and it <em>is</em> calling <code>unbindService</code>:</p> <pre><code>/** * Inform the library that the context is about to be destroyed, so that * any open connections can be cleaned up. * <p> * Failure to call this method can result in a crash under certain * circumstances, such as during screen rotation if an Activity requests * the license check or when the user exits the application. */ public synchronized void onDestroy() { cleanupService(); mHandler.getLooper().quit(); } </code></pre> <p>So, what is really going on?</p> <p>Is this a bug in LVL?</p>
