To run the demo, you need to have Android Studio installed on your computer and follow these steps:
- Head to CometChat Pro and create an account
- From the dashboard, add a new app called "typing-indicator-android-kotlin"
- Select this newly added app from the list.
- From the Quick Start copy the APP_ID, APP_REGION and AUTH_KEY. These will be used later.
- Also copy the REST_API_KEY from the API & Auth Key tab.
- Navigate to the Users tab, and delete all the default users and groups leaving it clean (very important).
- Download the repository here or by running
git clone https://github.com/hieptlccc/typing-indicator-android-kotlin.git
and open it in a code editor. - Head to Firebase and create a new project
- Create a folder called
constants
in the package folder of your project. - Create a file called
Constants.kt
in theconstants
folder of your project. - Import and inject your secret keys in the Constants.kt file containing your CometChat and Firebase in this manner.
interface Constants {
companion object {
const val COMETCHAT_APP_ID = "xxx-xxx-xxx-xxx-xxx-xxx-xxx-xxx"
const val COMETCHAT_REGION = "xxx-xxx-xxx-xxx-xxx-xxx-xxx-xxx"
const val COMETCHAT_AUTH_KEY = "xxx-xxx-xxx-xxx-xxx-xxx-xxx-xxx"
const val COMETCHAT_API_KEY = "xxx-xxx-xxx-xxx-xxx-xxx-xxx-xxx"
const val FIREBASE_REALTIME_DATABASE_URL = "xxx-xxx-xxx-xxx-xxx-xxx-xxx-xxx"
const val FIREBASE_EMAIL_KEY = "email" // this is not a secret value, it is just a constant variable that will be accessed from different places of the application.
const val FIREBASE_USERS = "users" // this is not a secret value, it is just a constant variable that will be accessed from different places of the application.
const val FIREBASE_ID_KEY = "id" // this is not a secret value, it is just a constant variable that will be accessed from different places of the application.
}
