makeWebRequest and error -403

Where in your code are you getting the exception?  It could be in your background service or in your glance view.

When you see 32k for a background service, what your app has is 28k, You can see this in the bottom line of the sim.

Also when showing a glance, it's not 32k(well 28k) for the backgound (:background annotation) and the same for the glance (:glance annotation)

it's a total of 32k/28k for both.

Hi Jim,

It's a makeWebRequest called made from onTemporalEvent, so a background process. Peak memory above shows 18.8 KB, which leaves 9.2 KB for data and such. My makeWebRequest response was 6.7 KB so technically it shouldn't have ran out, especially since I'm not even converting the data received into a Dictionary.

Hi again,

Down to almost its basic format, I still get error -403. I fail to see how this code can take all that space:

PS. Sorry for the inline pasting, I tried to insert it as code, but I get a 'You have been blocked" when I try to insert the code :-O I stripped the code of all its comments to better show its limited space.

        AppBase.initialize();

        }

    }
}

So, I dropped the whole project to just these functions and I've emptied them to almost all their code, that's what is left:

(:background)
class TeslaLink extends App.AppBase {
    function initialize() {
        AppBase.initialize();
    }

    (:can_glance)
    function getServiceDelegate(){
        return [ new MyServiceDelegate() ];
    }

    (:can_glance)
    function onBackgroundData(data) {
    }  

    (:glance, :can_glance)
    function getGlanceView() {
        return [ new GlanceView() ];
    }

    function getInitialView() {
    }
}

(:glance, :can_glance)
class GlanceView extends Ui.GlanceView {
    
  function initialize() {
    GlanceView.initialize();
  }

  function onUpdate(dc) {
  }
}

(:background, :can_glance)
class MyServiceDelegate extends System.ServiceDelegate {

    function initialize() {
        System.ServiceDelegate.initialize();
    }

    function onTemporalEvent() {
    }
}

The only strings defined with glance or background are these five.

    <string id="vehicle" scope="glance">vehicle</string>
    <string id="label_asleep" scope="background">Asleep</string>
    <string id="label_status_unknown" scope="glance">Status unknown</string>
    <string id="label_launch_widget" scope="background">Launch widget</string>
    <string id="label_waiting_data" scope="background">Waiting for data</string>

And yet, the memory footprint of the app is still 17,6 KB at its peek and 11.6 KB while basically doing nothing.

Is this normal?

10KB of that space turns out to be space taken by settings.xml. Most of that stuff is irrelevant to the glance code, is there a way to prune it for glance/background?

no

Well that's a bust, if the properties aren't the the watch specific resource file, it grabs them from the default one. I would need to put the 16 entries in the default one but that would mean all watches not limited to 32KB of background space (including all watches without Glance) would need its own resource directory. I think I'll change tactic and put a field where the user will enter in a coma separated way the order they want the items to appear in the menu. Will take way less space.
