why Symbol Not Found error for global variables?

Former Member over 6 years ago

Recently ERA reports that many users have the Symbol Not Found Error.

But the code looks OK (I actually put the checking cod [ if ($ has :variable_name) ] to make sure, but the error is happening on this line.

Does anyone know what's wrong with my code??

////////////////
// globals
...

var ana_1hz = 1;

...

class MyDelegate extends Toybox.WatchUi.WatchFaceDelegate {
...
        function onPowerBudgetExceeded(powerInfo) {
...
                if ($ has :ana_1hz){ $.ana_1hz = 0; }
...
        }
}

Check the firmware version in the ERA, as there's a known problem where apps can be installed on devices that don't have the proper minimum.

And weird things can happen.

Also, looks like you're missing the initialize() in your delegate - that should cause this error but you should get a compile warning.

function initialize() {
WatchFaceDelegate.initialize();
}

Thank you for the advice, seems like their firmware is not latest...

Strangely "Too Many Arguments Error" happening in the same line:

The actual code is below, so maybe the users' firmware are just too old?


class MyDelegate extends Toybox.WatchUi.WatchFaceDelegate {
        function initialize(){
                Toybox.WatchUi.WatchFaceDelegate.initialize();
        }
        function onPowerBudgetExceeded(powerInfo) {
            System.println( "Average execution time: " + powerInfo.executionTimeAverage );
            System.println( "Allowed execution time: " + powerInfo.executionTimeLimit );
            if ($ has :alwaysActive){ $.alwaysActive = false; }
            if ($ has :ana_1hz){ $.ana_1hz = 0; } 
        }
}

Probably I should put the warning notice to the app page, "Please update firmware of your device" or something, I guess..
