如何使用appcelerator构建服务Android

Question

I'm building a service with appcelerator studio. This is the code that I have building in Index.js page:

var intent = Titanium.Android.createServiceIntent( { url: 'myservice.js' } );
// Service should run its code every 2 seconds.
intent.putExtra('interval', 60000);
// A message that the service should 'echo'
//intent.putExtra('message_to_echo', 'Bo uscirà questo messaggio?');

var service = Titanium.Android.createService(intent);
service.addEventListener('resume', function(e) {
    Titanium.API.info('Service code resumes, iteration ' + e.iteration);
});
service.addEventListener('pause', function(e) {
    Titanium.API.info('Service code pauses, iteration ' + e.iteration);
    if (e.iteration === 1) {
        var _model = Alloy.createModel("ServiceDAO", {
            ID : 1,
            ServiceRunning: 0,
            ApplicationRunning: 0
        });
    _model.save();    
    }
});
service.start();

Now when I try to start the application, the myservice.js is execute every 60 second, but I have two problem:

1) when the service is running, I have a performance problem with interface 2) If I close the application, the service is not running.

So how can I implement a service with appcelerator that run in background also when the app is not running?

I tried this once: http://docs.appcelerator.com/platform/latest/#!/guide/Android_Services-section-43287937_AndroidServices-ServiceCode and seems to work fine. To log even with the app closed, you should use ADB logcat. Also, don't forget to include it in your tiapp.xml like:

<services>
    <service url="your_service_name.js" type="interval"/>
</services>
