Simple Background Service

[Durga Prasad]

Is it possible to create a background service which will check periodically or always, a notepad file uploaded in webserver, and display the contents in app notification. I have checked the music service, but I am not sure how to relate with this situation.

Any help appreciated.

If I was trying to do that, I would write a simple DroidScript app with no layouts that uses setInterval to do the job.

Once I had that working, I would convert it to a service afterwards, where the original code becomes Service.js and a front-end app for starting and stopping based on MusicService.js

If you get stuck along the way, feel free to post your code and I am sure lots of help will be available

Hi Steve,

I was trying with some samples of creating background services. I tried initially with set interval to show pop-up every 1 second. And it got worked. But the same when I applied service started, then I got error like "unfortunately Droidscript stopped".

In service I just tried to show the popup without set interval.

Here is my service.js file code

//Start/connect to our service.
svc = app.CreateService( "this","this", OnServiceReady );
//svc.SetOnMessage( OnServiceMessage );

//Called after our service has started.
function OnServiceReady()
{
//console.log( "Service Ready" );
app.ShowPopup("service ready");
}


How to use the services properly in app?

This was my attempt at doing what you described
http://wiki.droidscript.me.uk/doku.php?id=sample_code:file_service

I think this spk contains the same code as the wiki sample.

Thanks Steve! Wiki code is worked for my need. But in the notifications part, I am unable to make few things like below.

1) app.vibrate (it doesn't recognize any vibration code while notification)

2) setting large image works, but still small image contains Droidscript logo

[Durga Prasad]

I just make it worked app vibrate.

Are you testing an APK?

The notifications sample that comes with DroidScript contains the following comment

//Called when user presses notify with image button.
//Note: The small icon cannot be changed when running with
//the DroidScript IDE, but it will pickup your app icon when
//if you build an APK.

Yes after clearing my cache memory and rebuilding the apk finally it worked now!
