Walkthrough

This update modifies the Gradle build script to change how the build directory is referenced during the clean task, updates the Android Gradle Plugin version in the configuration, and simplifies a log statement in the MainActivity. These changes support elimu.ai's mission to build innovative learning software that empowers out-of-school children to teach themselves basic reading📖, writing✍🏽 and math🔢 within 6 months.

Changes

File(s)	Change Summary
build.gradle	Modified the clean task to reference the build directory using the layout API instead of direct property access.
gradle/libs.versions.toml	Updated the Android Gradle Plugin version from 8.6.0 to 8.6.1.
app/src/main/java/.../MainActivity.kt	Simplified a log statement by changing string interpolation from "language: ${language}" to "language: $language".

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Explain this complex logic.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai explain this code block.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
