Installing Android Java Chat UI Kit

Setup 🔧

To setup Android Chat UI Kit, you need to first register on CometChat Dashboard. Click here to sign up.

i. Get your Application Keys 🔑

1. Create a new app: Click Add App option available → Enter App Name & other information → Create App
2. You will find APP_ID, AUTH_KEY and REGION key at top in QuickStart section or else go to "API & Auth Keys" section and copy the APP_ID, AUTH_KEY and REGION key from the "Auth Only API Key" tab.

ii. Add the CometChat Dependency

Step 1 - Add the repository URL to the project level build.gradle file in the repositories block under the allprojects section.

allprojects { repositories { maven { url "https://dl.cloudsmith.io/public/cometchat/cometchat-pro-android/maven/" } } }

Step 2- Open the app level build.gradle file and follow below

1. Add the below line in the dependencies section.

dependencies { implementation 'com.cometchat:pro-android-chat-sdk:3.0.9' /** From v2.4+ onwards, Voice & Video Calling functionality has been moved to a separate library. In case you plan to use the calling feature, please add the Calling dependency.**/ implementation 'com.cometchat:pro-android-calls-sdk:2.2.0' }

2. Add the below lines android section

android { compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } }

You can refer to the below link for instructions on how to do so:

Configure CometChat SDK

i. Initialize CometChat 🌟

The init() method initializes the settings required for CometChat. We suggest calling the init() method on app startup, preferably in the onCreate() method of the Application class.

import com.cometchat.pro.core.AppSettings; import com.cometchat.pro.core.CometChat; import com.cometchat.pro.exceptions.CometChatException; String appID = "APP_ID"; // Replace with your App ID String region = "REGION"; // Replace with your App Region ("eu" or "us") AppSettings appSettings=new AppSettings.AppSettingsBuilder().subscribePresenceForAllUsers().setRegion(region).build(); CometChat.init(this, appID,appSettings, new CometChat.CallbackListener<String>() { @Override public void onSuccess(String successMessage) { Log.d(TAG, "Initialization completed successfully"); } @Override public void onError(CometChatException e) { Log.d(TAG, "Initialization failed with exception: " + e.getMessage()); } });

ℹ️   Note: Make sure to replace region and appID with your credentials.

ii. Login User 👤

Once you have created the user successfully, you will need to log the user into CometChat using the login() method.

import com.cometchat.pro.core.CometChat; import com.cometchat.pro.exceptions.CometChatException; String UID = "user1"; // Replace with the UID of the user to login String authKey = "AUTH_KEY"; // Replace with your App Auth Key if (CometChat.getLoggedInUser() == null) { CometChat.login(UID, authKey, new CometChat.CallbackListener<User>() { @Override public void onSuccess(User user) { Log.d(TAG, "Login Successful : " + user.toString()); } @Override public void onError(CometChatException e) { Log.d(TAG, "Login failed with exception: " + e.getMessage()); } }); } else { // User already logged in }

ℹ️   Note - The login() method needs to be called only once. Also replace AUTH_KEY with your App Auth Key.

Add UI Kit Library

1. Simply clone the project from android-java-chat-ui-kit repository.

2. Import uikit Module from Module Settings.( To know how to import uikit as Module visit this link )

3. If the Library is added successfully, it will look like mentioned in the below image.

4. Next steps is to adding necessary dependencies inside your app to integrate UI Kit.

   • To use UI Kit you have to add Material Design Dependency as the UI Kit uses Material Design Components.

     implementation 'com.google.android.material:material:<version>'

     Also please make sure that your app's theme should extend Theme.MaterialComponents. Follow the guide on Getting started Material Components

     The following is the list of Material Components themes you can use to get the latest component styles and theme-level attributes.

     Theme.MaterialComponents.NoActionBar
Theme.MaterialComponents.Light.NoActionBar
Theme.MaterialComponents.DayNight.NoActionBar
Theme.MaterialComponents.DayNight.NoActionBar.Bridge
     

     Update your app theme to inherit from one of these themes, e.g.:

     <style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar.Bridge"> <!-- Customize your theme here. --> </style>

   • Replace **YOUR_PACKAGE_NAME** with your application package name:

     android { defaultConfig { manifestPlaceholders = [file_provider: "YOUR_PACKAGE_NAME"] //add your application package. } }

   • As the UI Kit uses dataBinding you must enable dataBinding to use UI Kit.To configure your app to use data binding, add the dataBinding element to your `build.gradle` file in the app module, as shown in the following example:

     android { ... dataBinding { enabled = true } }

   • Open the gradle.properties and check if the below stated line is present or not, if not then simply add it.

     android.enableJetifier=true
