Build One-on-One Android Chat App in Kotlin  23 | The article on how to build one-on-one Android chat app in Kotlin is now published. You can read it on this link here. →. 24 |

25 | 26 | Chaty is an Android Demo app (using **CometChat Pro**) for a fully functional messaging app capable of **one-on-one** (private) messaging. The app enables users to send **text** messages to other users in realtime. 27 | 28 | This example shows how to build an one-to-one chat with Android using Kotlin. 29 | 30 | [![Platform](https://img.shields.io/badge/Platform-Android-brightgreen.svg)](#) [![Platform](https://img.shields.io/badge/Language-Kotlin-yellowgreen.svg)](#) 31 | 32 | ## ScreenShots 33 | 34 |
35 | 36 |
37 | 38 | ## Technology 39 | This demo uses: 40 | 41 | * CometChat Pro Android SDK (1.3.+) versions 42 | * Android and Kotlin 43 | * Material Components by Google 44 | * Glide for Image Loading 45 | 46 | ## Installation 47 | 48 | Simply Clone the project from android-kotlin-chat-app repository and open in Android Studio. 49 | Build the Demo App and it will be ready to Run 50 | 51 | 52 | ## Run the Sample App 53 | To run the demo follow these steps: 54 | 55 | 1. [Head to CometChat Pro and create an account](https://cometchat.com/pro?utm_source=github&utm_medium=wajahatkarim3-chaty-readme) 56 | 2. From the [dashboard](https://app.cometchat.com/?utm_source=github&utm_medium=wajahatkarim3-chaty-readme), create a new app called "One-To-One Android Chat" 57 | 3. Once created, click **Explore** 58 | 4. Go to the **API Keys** tab and click **Create API Key** 59 | 5. Create an API key called "Android One-To-One Chat Key" with **Full Access** 60 | 4. Download the repository [here](https://github.com/wajahatkarim3/Chaty/archive/master.zip) or by running `git clone https://github.com/wajahatkarim3/Chaty.git` and open it in Android Studio 61 | 5. Update [strings.xml](https://github.com/wajahatkarim3/Chaty/blob/master/app/src/main/res/values/strings.xml) with your newly-created `appID` and `apiKey` 62 | 6. Run the app and login with one of the test users: superhero1, superhero2, superhero3, superhero4 or superhero5 63 | 64 | Questions about running the demo?
