info has :distanceToDestination

On my new Venu X1 the datafield does not support distanceToDestination

It crashes if 'if (info has :distanceToDestination) {' is not used

ConnectIq SDK 8.4.1

Are you sure? Can it be that you want to check for null?

during a workout the value is present on a normal datafield (so not null and exists) but not available on a connectIQ datafield

Installed the same datafield app on my Fenix 7X and ik works there

Do both a has check and a check for null. It could be null before you start recording, for example.

jim_m_58 what is the better has check? Activity.Info has :distanceToDestination or info has :distanceToDestination? IMHO the 1st is better because it enables the compiler to eliminate branches that are irrelevant for the device.

//if (info has :distanceToDestination) {

if (info.distanceToDestination != null) {

_remaining = info.distanceToDestination / 1000;

} else {

_remaining = 0;

}

//}

I tried also with the has :, it alwais keeps 0 (on a Venu X1)

It is CIQ 6.0, on the fenix it is 5.2, could it be a 6.0 bug?

The "info" passed to compute is Activity.Info

"info as Activity.Info"

In a data field you might never need to call Activity.getActivityInfo() as you already see it in compute()

You'll notice that everything in info can be "or Null" so you want to do null checks

BTW, I ALWAYS do run-time "has" checks as the actual FW on a device can be different/newer/older that the device in the sim.

I see that the SDK does not have CIQ 6.0 devices yet, are the 5.2.0 devices used for compiling?

jim_m_58 1 hour ago in reply to jpbusman

If the device supports 5.2.0. yes If the specific device only supports a lover level of CIQ, then it uses that. When you run in sim, the title bar shows you the device you are simulating as well as the CIQ level being used.
