Wear OS - User interface populates with default information prior to GNSS fix

[barbeau]

Describe the bug When the Wear OS app is first started, the user interface populates with default (i.e., not real) GNSS information.

Here's an example picture:

For example:

• Time is 19:00:00
• Lat: is 0.0000000
• Long: is 0.00000
• Bearing: is 0.0
• PDOP: is NaN

These fields should all be blank before real information is reported from the Android APIs - in other words, they should be initialized to empty values.

Here are some examples for how this is handled with Compose in the mobile app Status screen:

• https://github.com/barbeau/gpstest/blob/master/GPSTest/src/main/java/com/android/gpstest/ui/status/StatusScreen.kt#L315
• https://github.com/barbeau/gpstest/blob/master/GPSTest/src/main/java/com/android/gpstest/ui/status/LocationCard.kt#L195
• https://github.com/barbeau/gpstest/blob/master/GPSTest/src/main/java/com/android/gpstest/ui/status/LocationCard.kt#L229
• https://github.com/barbeau/gpstest/blob/master/GPSTest/src/main/java/com/android/gpstest/ui/status/LocationCard.kt#L164

The one exception is "# Sats" - we can keep this as 0/0/0 until it populates with real data.

@adaext Is this something you could tackle?

To Reproduce Steps to reproduce the behavior:

1. Start Wear OS app and wait for a GNSS fix

Expected behavior Fields with data should be initialized to empty values

Observed behavior Fields are populated to default values
