Android Kotlin Mentor-Kotlin and Android guidance.

Example

A developer encounters a flaky test when using Espresso for UI testing in a RecyclerView scenario. The mentor provides detailed advice on test synchronization, proper usage of `IdlingResource`, and other best practices to stabilize the test.

Scenario

In a real-world app, the developer has multiple UI tests failing due to improper synchronization between the app's background threads and the UI thread. Android Kotlin Mentor explains how to implement `IdlingResource` or leverage `await()` in Coroutines to make the tests more robust.

Example

A developer is unsure how to structure their app to separate concerns between UI logic and business logic. The mentor helps them implement MVVM architecture with clear separation of responsibilities between View, ViewModel, and Repository layers, demonstrating the use of LiveData and Coroutines for data flow.

Scenario

In a project with complex features, the developer finds that business logic is leaking into the UI layer, leading to hard-to-maintain code. Android Kotlin Mentor helps restructure the project, moving logic into appropriate ViewModel and Repository classes, implementing use cases, and organizing dependency injection using Dagger/Hilt.

Example

The mentor provides guidance on how to share code between Android and iOS platforms using Kotlin Multiplatform, helping a team build shared modules for networking, data handling, and business logic.

Scenario

A team wants to maintain a single codebase for business logic that works across Android and iOS. Android Kotlin Mentor shows them how to set up a Kotlin Multiplatform project, define shared modules, and properly handle platform-specific implementations where necessary.

Example

The mentor provides insight into performance bottlenecks by suggesting improvements like reducing the number of nested layouts, using `ConstraintLayout` effectively, and optimizing RecyclerView performance through ViewHolder recycling.

Scenario

An app with laggy scrolling in a RecyclerView struggles with performance issues due to improper view recycling. Android Kotlin Mentor analyzes the code and shows how to improve view recycling and use DiffUtil for optimal performance.
