What is causing this IllegalArgumentException: Service not Registered?

Question

Whenever I either rotate the phone or press the Home button the application crashes and I get the following exception:

11-25 22:17:23.855: E/AndroidRuntime(5033): FATAL EXCEPTION: main

And this is mConnection

  /** Defines callbacks for service binding, passed to bindService() */
private ServiceConnection mConnection = new ServiceConnection() 
{

    @Override
    public void onServiceConnected(ComponentName className,
            IBinder service) {
        // We've bound to LocalService, cast the IBinder and get LocalService instance
        LocalBinder binder = (LocalBinder) service;
        mService = binder.getService();
        mBound = true;
    }

    @Override
    public void onServiceDisconnected(ComponentName arg0) {
        mBound = false;
    }
};

I already registered my service - At least I think I did so by inserting the following in my manifest :

<service android:name="StationService" />

Answer 1

I realised my problem was unbinding my service at times when the service wasn't bound in the first place. Only unbinding the service in onPause() seems to have solved my problem.

Answer 2

Be sure that you are binding and unbinding from the same context. I was getting this error and discovered it was because I had previously implemented a context wrapper with which I was binding my service. My unbind was on the View context and so it had no knowledge of the service binding/registration.
