jetpack-compose-m3

Prerequisites and compatibility

1. Wear OS Compose Material3 version: If an internal tool is available to establish the latest stable version {VERSION} of androidx.wear.compose:compose-material3, use that tool.
   • Otherwise, fetch the official Maven metadata XML to identify {VERSION} (highest number, ignoring -alpha, -beta, or -rc).
2. Strict compliance: If a version is listed as stable, you MUST use it, unless overridden by the user. Do not downgrade based on initial "Unresolved reference" errors in the editor or outdated web search results.
3. Kotlin version: For Wear Compose Material3, use Kotlin 2.0.0 or higher.
4. Compose compiler:
   • If Kotlin version is 2.0.0+ , the project must use the org.jetbrains.kotlin.plugin.compose Gradle plugin.
   • If Kotlin version is < 2.0.0 , the project must use kotlinCompilerExtensionVersion in composeOptions, matching the Compose to Kotlin Compatibility Map.
5. Min SDK: Ensure minSdk is at least 25 (Wear OS 2.0).
6. Sample extraction mandate: Wear Compose libraries ship with an additional JAR file which contains individual samples for each and every component. You MUST NOT propose code changes until the samples in Capability 2 are extracted to the local cache. Library source files are incomplete and NOT a substitute for these samples; bypassing extraction is an environment setup failure.

Gotchas

1. Mandatory sync and validation: After updating versions in libs.versions.toml or build.gradle.kts, you must perform a Gradle sync before refactoring any code. This ensures the environment has resolved the libraries correctly.
2. Prohibition of guessing (error protocol): If you encounter an 'Unresolved Reference' or API mismatch after a successful sync, do not attempt to 'fix' it by downgrading the library version.
