Question

I have a pretty simple local service that I’m trying to bind to my activity. I worked through this yesterday with CommonsWare and he got me straightened out as I was having a difficult time getting the service to bind. It turns out that the reason I was having so much trouble was that I was trying to bind the service with:

bindService(new Intent(this, myService.class), mConnection, Context.BIND_AUTO_CREATE);

inside a void method that was being called after a button click.

private void doBindService() {
            bindService(new Intent(this, SimpleService.class), mConnection, Context.BIND_AUTO_CREATE);
            mIsBound = true;
        }

       private OnClickListener startListener = new OnClickListener() {
        public void onClick(View v){
            doBindService();
        }               
       };

when I moved my bindService() call to the onCreate method of the activity, it works fine. CommonsWare mentioned something about that call being asynchronous and I don’t know enough about android activity creation to know if that’s what my issue was or not. I do know that my onServiceConnection() was being called inside my ServiceConnection() when the button was being clicked, by my mBoundService would not work when I tried accessing members inside the service.

Can someone tell me why it doesn’t work inside the button click, but does work inside the onCreate()?

TIA

Answer 1

The this reference inside of doBindService is not the same in both instances. If called in onCreate it will be a reference to the Activity if called from the button click it will be a reference to the OnClickListener. Obviously you do not want your service bound to the buttons click listener.

Try changing this to YOURACTIVITYNAME.this and see if that helps.
