android – Unable to destroy Activity (service is not registered)

Questions:

*EDIT SOLVED BY DOING THIS:*
I have solved it by changing my onDestroy() of my Activity and the ServiceConnection::onServiceDisconnected().

I have added a boolean to check if I’m bounded to the Service called boundToService.
The ServiceConnection:

private ServiceConnection mConnection = new ServiceConnection() {
    public void onServiceConnected(ComponentName className, IBinder service) {
        myService = ((EventService.MyBinder) service).getService();
    }

    public void onServiceDisconnected(ComponentName name) {
        // TODO Auto-generated method stub
        Log.i(getPackageName(), "ServiceConnection::onServiceDisconnected() called");
        boundToService = false;
    }
};

And the onDestroy():

@Override
protected void onDestroy() {
    // TODO Auto-generated method stub
    super.onDestroy();
    Log.e(getPackageName(), "Destroying Activity");
    if (boundToService && mConnection != null) {
        doUnbindService();
    }
}

This is how the binding and unbinding is done in the activity:

public void doBindService() {
    bindService(new Intent(this, EventService.class), mConnection,
            Context.BIND_AUTO_CREATE);
    boundToService = true;
}

public void doUnbindService() {
    unbindService(mConnection);
    boundToService = false;
}

As Guillaume said, calling super.onDestroy() first is a must.

*END OF SOLVE*

I have a Foreground Service that polls GPS data, and the MapActivity requests that data every 3 seconds. When the onDestroy() of the MapActivity is called, I get this LogCat error:

And of course the code around line 175 where the exception is caused in my program:

@Override
protected void onDestroy() {
    // TODO Auto-generated method stub
    unbindService(mConnection);
    super.onDestroy();
}

If you want more code snippets, just tell me.

*edit*

This is the code for the ServiceConnection:

public void doBindService() {
    //ComponentName service = startService(new Intent(this,
        //  EventService.class));
    bindService(new Intent(this, EventService.class), mConnection,
            Context.BIND_AUTO_CREATE);
}

mConnection is type of ServiceConnection:

private ServiceConnection mConnection = new ServiceConnection() {
    public void onServiceConnected(ComponentName className, IBinder service) {
        myService = ((EventService.MyBinder) service).getService();
    }

    public void onServiceDisconnected(ComponentName name) {
        // TODO Auto-generated method stub

    }
};
How to&Answers:

That’s worked for me ! Just call the function unbindService() from getApplicationContext() instead of “this” context. (same for binding the service)

getApplicationContext().unbindService(mServiceConnection);

Answer:

You could just set mService to null in onServiceDisconnected and check for that in onDestroy. Like this:

private ServiceConnection mConnection = new ServiceConnection() {
        @Override
        public void onServiceConnected(ComponentName className, IBinder binder) {
            mService = ((LoadArticlesService.LoadArticlesBinder) binder).getService();
        }
        public void onServiceDisconnected(ComponentName className) {
            mService = null;
        }
    };

onDestroy:

@Override
protected void onDestroy() {
    super.onDestroy();
    if (mService != null) {
        unbindService(mConnection);
    }
}

Works fine.
