19 | 20 | This is an Android chat application built using Kotlin and Kotlin Flow. The application allows users to send and receive messages in a chat room. 21 | 22 | ## Getting Started 23 | [![Project Status: Active – The project has reached a stable, usable state and is being actively developed.](https://www.repostatus.org/badges/latest/active.svg)](https://www.repostatus.org/#active) 24 | [![Compatible with Compose — 1.4.0](https://img.shields.io/badge/Compatible%20with%20Compose-1.4.0-brightgreen)](https://developer.android.com/jetpack/androidx/releases/compose-foundation#1.4.0) 25 | [![Material design 3](https://img.shields.io/badge/Material%20Design%203-1.0.1-brightgreen)](https://developer.android.com/jetpack/androidx/releases/compose-material3#1.0.1) 26 | 27 | ## Features 28 | - Real-time messaging using Kotlin Flow. 29 | - Users can send and receive messages in a chat room. 30 | - Simple user interface with a clean and modern design. 31 | 32 | This project contains four modules 33 | - `:ui:legacy`, demonstrates of the Android chat using legacy android XML layouts 34 | - `:ui:compose`, demonstrates of the Android chat using Jetpack Compose layouts 35 | - `:ui:core`, share module for both legacy and compose modules with sharing resources 36 | - `:data`, data modules for providing chat messages, and submitting outgoing messages using a repository 37 | 38 | ## Dependencies 39 | - Android Architecture Components: ViewModel 40 | - Kotlin Coroutines. 41 | - Kotlin Flow. 42 | - Material Design Components. 43 | 44 | ## Installation 45 | 1- Clone the repository: 46 | ```bash 47 | git clone https://github.com/mo0rti/android-blueprint-kotlin-flow-chat.git 48 | ``` 49 | - Open the project in Android Studio. 50 | - Build and run the application on an emulator or physical device. 51 | 52 | ## Usage 53 | - Launch the application. 54 | - Enter a username and click on the login button to enter the chat room. 55 | - Type a message in the text field at the bottom of the screen and click on the send button to send the message. 56 | - Incoming messages will appear in the chat room in real-time. 57 | 58 | ## Contributing 59 | Contributions to this project are welcome. To contribute, please follow these steps: 60 | 61 | - Fork the repository. 62 | - Create a new branch. 63 | - Make your changes and commit them. 64 | - Push your changes to your fork. 65 | - Create a pull request. 66 | - Please ensure that your pull request follows the project's coding style and that it includes appropriate tests. 67 | 68 | The Kotlin Flow Chat Application is a great project to learn Kotlin SharedFlow because it demonstrates how to use SharedFlow to build a chat application that supports real-time messaging. 69 | Here are brief explanations of the three main classes in the project: 70 | ## ChatRepository 71 | The `ChatRepository` class is responsible for managing the chat messages. It provides methods to send and receive chat messages and exposes a `SharedFlow` of incoming messages. The `incomingMessages` flow emits incoming chat messages as they arrive and can be observed by clients to display the chat history. The `sendMessage` method sends a chat message to the server. It takes a `username` and `content` as input parameters and emits a new `ChatMessage` with `MessageType.OUTGOING`. The `simulateIncomingMessages` method simulates incoming chat messages for testing purposes. It emits a random chat message every 500-2000 milliseconds until a fixed number of messages is reached. 72 | 73 | ## ChatViewModel 74 | The `ChatViewModel` class is responsible for managing the chat messages and providing an interface for the UI to interact with the chat. It provides a `sendMessage` method to send chat messages and exposes a `SharedFlow` of incoming messages. The `incomingMessages` flow emits incoming chat messages as they arrive and can be observed by clients to display the chat history. The `sendMessage` method delegates to the `ChatRepository` to send the message to the server. The method takes a `username` and `content` as input parameters and forwards them to the repository for processing. 75 | 76 | ## ChatAdapter (Legacy Android UI XML format) 77 | The `ChatAdapter` class is responsible for displaying the chat messages in the `RecyclerView` in the `ChatActivity`. It extends the `ListAdapter` class and implements the `DiffUtil.ItemCallback` interface to efficiently handle changes in the list of chat messages. The `addMessage` method is used to add a new chat message to the list of messages and update the UI. 78 | 79 | Overall, this project is a great example of how to use Kotlin SharedFlow to build a real-time messaging feature in an Android application. It demonstrates how to use the `MutableSharedFlow` and `SharedFlow` classes to emit and observe messages, and how to use coroutines to manage concurrency and perform asynchronous operations. It also shows how to use the `ViewModel` architecture component to separate the UI and data layers of the application and how to use the `ListAdapter` class to efficiently handle changes in the list of chat messages. 80 | 81 |
