Adding Material Expressive to Jetcaster and merging gerrit code

[gemini-code-assist]

Hello @MagicalMeghan, 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!

Summary of Changes

Hello team! Gemini here, providing a summary of this pull request titled "Jetcaster Material Expressive update".

The primary goal of this PR, as indicated by the title and description, is to integrate Material Expressive design principles and components into the Jetcaster application. This involves updating the visual theme (colors, typography) and replacing standard Compose Material 3 components with their Material Expressive counterparts where appropriate. Additionally, the PR merges code from a Gerrit source, which includes adding functionality for handling multiple media URLs for episodes and implementing episode deletion.

Key areas impacted include the core data layer (adding media URLs and delete functionality), the design system (colors, typography, custom components), the mobile UI (Home, Player, Podcast Details screens adopting Material Expressive components and transitions), the TV player (integrating Media3), and the Glance/Wear modules (minor updates).

Highlights

• Material Expressive Adoption: The application's theme is updated to use Material Expressive colors and typography. Several standard Material 3 components are replaced with Material Expressive versions, such as carousels, buttons (ToggleButton, ButtonGroup), and swipe-to-dismiss.
• Episode Media URLs: The Episode data model is extended to support a list of media URLs, and the RSS fetching logic is updated to parse these from enclosures. A Room TypeConverter is added for persistence.
• Episode Deletion: Functionality to delete episodes is added to the data layer (EpisodeStore) and exposed through the Home and Podcast Details ViewModels. Swipe-to-dismiss is implemented in the episode list items to trigger deletion.
• Shared Element Transitions: Experimental Shared Element Transitions are introduced in the mobile UI, specifically between the Home screen's episode list items and the Player screen's episode image.
• Media3 Integration (TV): The TV module is updated to integrate the Media3 library for audio playback, replacing the previous custom player logic.

Code Review

This pull request brings a substantial Material Expressive theme update to Jetcaster, enhancing the visual appeal and user experience with new components and shared element transitions. The data handling for episodes has been improved with support for multiple media URLs and deletion capabilities. The TV player's direct ExoPlayer integration is also a notable enhancement.

The code is generally well-organized, and the UI changes are consistent with the Material Expressive guidelines. I have a few suggestions, primarily around data robustness and minor maintainability points.

As I am an AI, I am not authorized to approve pull requests. Please ensure that this PR is reviewed and approved by other maintainers before merging.

Summary of Findings

• Data Robustness: Comma in Media URLs: The ListOfStringConverter in Episode.kt uses a comma delimiter. If a media URL contains a comma, parsing will be incorrect. Consider JSON serialization for more robustness if this is a possibility.
• Data Robustness: Empty Media URLs in TV Player: The TV player's ExoPlayer integration directly accesses mediaUrls[0]. This could cause a crash if mediaUrls is empty. A check should be added.
• Maintainability: Repetitive UI Logic: The PillToolbar in Home.kt and PlayerButtons in PlayerScreen.kt (mobile) have some repetitive styling logic for selected/unselected states and button configurations. Consider refactoring if these patterns are reused.
• Dependency: Compose BOM Alpha: The androidx-compose-bom has been updated to androidx-compose-bom-alpha in libs.versions.toml. This implies using alpha versions of Jetpack Compose, which should be an intentional decision, as alpha versions might have API instability or bugs. (Not commented directly due to review settings)
• Code Style: Minor Formatting: Several files (JetcasterAppWidget.kt, JetcasterAppWidgetPreview.kt, Gradle files) have minor formatting changes (blank lines, trailing commas). These are generally fine and likely from an auto-formatter. (Not commented directly due to review settings)

Merge Readiness

This pull request introduces significant and positive changes, particularly with the Material Expressive update and shared element transitions. The codebase is generally in good shape.

However, I recommend addressing the high severity issue regarding potential crashes in the TV player due to empty mediaUrls before merging. The medium severity items related to the ListOfStringConverter robustness and potential refactoring of UI styling logic should also be considered for improvement, though they are not strictly blockers.

As an AI, I am not authorized to approve pull requests. Please ensure that this PR is reviewed and approved by other maintainers, especially after addressing the highlighted concerns.

The code exoPlayer.setMediaItem(MediaItem.fromUri(Uri.parse(currentEpisode.mediaUrls[0]))) assumes that currentEpisode.mediaUrls is not empty and that the first URL is always the one to play.

What is the expected behavior if mediaUrls is empty? This could lead to an IndexOutOfBoundsException. It might be prudent to add a check for mediaUrls.isNotEmpty() before attempting to access the first element, and perhaps handle the case where no media URL is available (e.g., show an error, disable playback).

            if (currentEpisode.mediaUrls.isNotEmpty()) {
                exoPlayer.setMediaItem(MediaItem.fromUri(Uri.parse(currentEpisode.mediaUrls[0])))
            } else {
                // Handle case where mediaUrls is empty, e.g., log an error or show a message
            }

[gemini-code-assist]

The ListOfStringConverter uses a simple comma (,) as a delimiter for storing a list of media URLs as a single string. While this works for many cases, could there be a scenario where a URL itself might contain a comma? If so, this would lead to incorrect parsing.

Consider if a more robust serialization method, like storing the list as a JSON array string (e.g., using kotlinx.serialization), might be safer for future-proofing, or if it's confirmed that media URLs will never contain commas.

The logic for determining libraryContainerColor, libraryContentColor, discoverContainerColor, and discoverContentColor within the PillToolbar is a bit repetitive for the two buttons. While it's clear for two items, if this pattern of conditional coloring for selected/unselected states were to expand or be reused, would it be beneficial to encapsulate this logic into a helper function or a data structure to reduce duplication and improve maintainability?

[gemini-code-assist]

The styling for the ToggleButton (play/pause) and the IconButtons within the ButtonGroup (skip, rewind, forward) involves detailed ToggleButtonColors, ButtonShapes, and IconButtonColors definitions. This provides a nice Material Expressive look.

If these specific color and shape configurations are intended to be standard for these types of controls throughout the app, would it make sense to define these custom color/shape sets as reusable constants or perhaps as part of an extended theme to promote consistency and simplify their application elsewhere?
