I am receiving this exception in LogCat every time I press the Back button in my app:
Activity has leaked ServiceConnection
com.android.vending.licensing.LicenseChecker@471cc039 that was
originally bound here
The code responsible for this leak in onCreate() is:
mLicenseCheckerCallback = new MyLicenseCheckerCallback();
mChecker.checkAccess(mLicenseCheckerCallback);
How do I get rid of this leak?
I tried not assigning MyLicenseCheckerCallback to a member, thinking perhaps when the activity goes onPause() the reference to the callback is responsible for the leak:
mChecker.checkAccess(new MyLicenseCheckerCallback());
But that didn't get rid of the leak.
Update: Thanks to @zapl's comment below, I looked at Google's LicenseChecker.java:
/** 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;
}
}
At first I thought that I may be neglecting to call it, but I double-checked
and I am calling mChecker.onDestroy(); in my activity's onDestroy().
I also checked onDestroy() in LicenseChecker.java
and it is calling unbindService:
/**
* 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();
}
So, what is really going on?
Is this a bug in LVL?
