It would be good to decide this now - so we can start to think about analytics etc. Perhaps chat-kotlin/x.y.z?

Just to check - the room lifecycle will be a separate PR?

49-56: Initialization of RealtimeClient and ChatApi looks good but consider environment-specific configurations.The initialization of
RealtimeClientandChatApiis done securely usingBuildConfig.ABLY_KEYand a random client ID. However, consider making the log level configurable based on the environment to avoid verbose logging in production.

.editorconfig (1)
10-10: Simplified Import Layout ConfigurationThe change to
ij_kotlin_imports_layoutsimplifies the import organization. While this can make the configuration easier to manage, it's important to verify that this does not lead to disorganized imports in larger projects.Consider reviewing a few Kotlin files to ensure that the new import layout does not adversely affect the organization and readability of imports.
gradle.properties (1)
19-19: Enhanced Build ConfigurationThe addition of
android.enableBuildConfigAsBytecodeis a positive change, potentially improving build performance. However, it's important to verify that this setting integrates well with the existing build processes and does not introduce unforeseen issues.Run a few build tests to ensure that enabling BuildConfig as bytecode does not negatively impact the build process or the final application performance.
example/src/main/AndroidManifest.xml (1)
16-16: Improved User Experience with Soft KeyboardThe addition of
android:windowSoftInputMode="adjustResize"is a thoughtful change, enhancing the user experience by ensuring that input fields remain visible when the soft keyboard is displayed. This adjustment is crucial for maintaining usability in interactive applications.chat-android/src/main/java/com/ably/chat/ChatClient.kt (1)
40-40: Factory method forChatClientimplementation.The addition of a factory method for creating instances of
ChatClientis a good practice as it encapsulates the instantiation logic and provides a clear entry point for client creation.chat-android/src/main/java/com/ably/chat/Utils.kt (2)
12-22: Utility functions for channel operations.The
attachCoroutineanddetachCoroutinefunctions are implemented using Kotlin coroutines, which is suitable for these asynchronous operations. The use ofCompletionListenerand proper error handling withresumeWithExceptionare correctly implemented.Also applies to: 24-34
42-42: Addressing the existing comment about version string.It's important to finalize the version string as suggested by the previous comment. This will aid in analytics and version tracking.

2-84: Interface Definition ApprovedThe
Roominterface is well-defined with clear documentation for each property and method. This provides a solid foundation for implementing chat room functionalities.example/src/main/java/com/ably/chat/example/MainActivity.kt (2)
72-118: Well-structuredChatcomposable function with efficient use of modern Kotlin features.The
Chatfunction is well-organized and makes good use of composables for modularity. The use ofLazyColumnfor displaying messages and coroutines for asynchronous operations are both efficient and appropriate for this context.
121-171: Effective implementation ofMessageBubbleandChatInputFieldwith attention to user experience.Both
MessageBubbleandChatInputFieldare implemented effectively, withMessageBubbleusing conditional styling to enhance user experience andChatInputFieldmanaging user input and sending state efficiently.chat-android/src/main/java/com/ably/chat/Messages.kt (1)
179-213: Review ofDefaultMessagesclass implementationThe
DefaultMessagesclass provides foundational methods for managing chat messages. Here are some observations and suggestions:
Channel Name Construction: The
messagesChannelNameis constructed usingroomId. Ensure that this naming convention aligns with backend expectations and doesn't introduce any security or functionality issues.private val messagesChannelName = "$roomId::\$chat::\$chatMessages"Method Implementations:
subscribeandunsubscribe: These methods are marked withTODOand not implemented. This is acceptable given the PR's current scope but should be prioritized in subsequent updates.get: Similar tosubscribe, it's marked withTODO. Consider adding a basic implementation or more detailed comments on intended functionality.send: This method is implemented to interact withchatApi. Ensure that error handling is robust, especially considering network issues or API failures.onDiscontinuityandoffDiscontinuity: Also marked withTODO. It's crucial to define how discontinuities will be handled in the chat flow.Error Handling and Logging: Given that the methods mostly throw
NotImplementedError, it's important to start planning for proper error handling and logging mechanisms to support debugging and ensure reliability.Testing: The class lacks associated unit tests. Given the critical nature of chat functionality, comprehensive tests are essential to ensure each method behaves as expected under various conditions.
Overall, the class sets up a good structure for the chat message handling but needs further implementation and robust testing to ensure reliability and functionality.
…for main classes In this PR most of the methods in the default implementations throws exceptions. We focused on happy path getting client, creating room, attaching to the room (without any corner cases)

libs.plugins.build.configenhances the build configuration management, which is a positive change for maintaining build consistency.
7-7: Approved: Addition of version variable.Defining
versionto manage the Ably Chat library version enhances clarity and maintainability of version management within the build script.
39-43: Approved: NewbuildConfigblock with dynamic version assignment.The introduction of the
buildConfigblock withAPP_VERSIONdynamically assigned enhances version management. Ensure that this dynamic assignment is thoroughly tested to confirm its correct functionality across different build scenarios.Run the following script to verify the dynamic version assignment:
chat-android/src/main/java/com/ably/chat/Utils.kt (3)
14-24: Approved: Coroutine-based channel attachment.The implementation of
attachCoroutineusing Kotlin coroutines and handling both success and error scenarios is correctly done and follows best practices for asynchronous operations.
26-36: Approved: Coroutine-based channel detachment.The implementation of
detachCoroutineis consistent withattachCoroutineand correctly uses Kotlin coroutines to manage asynchronous detachment operations.
38-46: Approved: Dynamic agent version in channel options.The function
ChatChannelOptionscorrectly sets the agent version usingBuildConfig.APP_VERSION. Ensure that this dynamic value is correctly implemented and tested across different build scenarios.Run the following script to verify the dynamic agent version assignment:
Verification successful
Verified: Dynamic agent version assignment is correctly implemented.
The
ChatChannelOptionsfunction correctly usesBuildConfig.APP_VERSIONto dynamically set the agent version. TheAPP_VERSIONis defined inbuild.gradle.ktsand is used appropriately in the codebase. No further issues were found.
APP_VERSIONis defined inbuild.gradle.kts.BuildConfig.APP_VERSIONis used inUtils.kt.Scripts executed

86-132: Review ofDefaultRoomImplementationThe
DefaultRoomclass provides a structured implementation of theRoominterface. Each property is initialized with a default implementation, which is a good practice for modularity and maintainability. However, the methods mostly contain TODOs, indicating that further implementation is needed to handle errors and edge cases.Suggestions:
- Implement error handling in methods like
attach()anddetach().- Consider adding unit tests to cover these methods to ensure they handle various scenarios correctly.
Would you like assistance in implementing these methods or creating unit tests?
