Summary of Changes

Hello @kul3r4, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request primarily focuses on modernizing the application's visual identity by updating the launcher icon for the Exercise sample Compose app to an adaptive and round format. This involves introducing new vector drawable assets for the icon's background and foreground. Additionally, a small, unrelated code cleanup was included in the service layer.

Highlights

• App Icon Update: The application icon for the Exercise sample Compose app has been updated to an adaptive icon, including a new round version, as specified in the PR description.
• New Drawable Assets: New vector drawable XML files (ic_launcher_background.xml and ic_launcher_foreground.xml) were added to define the visual components of the new adaptive icon.
• Code Cleanup: A minor code cleanup was performed in ExerciseService.kt, replacing the ServiceInfo.FOREGROUND_SERVICE_TYPE_NONE constant with its literal integer value 0.

Code Review

This pull request successfully updates the application icon to a round version by adding the necessary drawable and mipmap resources. The changes align with the description. My review includes one comment on a change in ExerciseService.kt that replaces a descriptive constant with a magic number. I recommend reverting this change to maintain code clarity.

[gemini-code-assist]

Using the magic number 0 here reduces code readability and maintainability. It's preferable to use the ServiceInfo.FOREGROUND_SERVICE_TYPE_NONE constant, as its name clearly communicates the purpose of the comparison.

Suggested change

	get() = this.foregroundServiceType != 0
	get() = this.foregroundServiceType != ServiceInfo.FOREGROUND_SERVICE_TYPE_NONE

[kul3r4]

ServiceInfo.FOREGROUND_SERVICE_TYPE_NONE is deprecated, elsewhere in the code 0 is used:

// Starting with Wear 5 (API 34), startForeground should be called with
                // foregroundServiceTypes
                ServiceInfo.FOREGROUND_SERVICE_TYPE_LOCATION or
                    if
                        (Build.VERSION.SDK_INT >= Build.VERSION_CODES.UPSIDE_DOWN_CAKE) {
                        ServiceInfo.FOREGROUND_SERVICE_TYPE_HEALTH
                    } else {
                        0
                    }
