Getting Started

To get rolling with Chat21 SDK, you need to meet some prerequisites:

• A properly configured Firebase project
• Chat21 Firebase cloud functions set up
• The google-services.json file for your app

Setup Instructions

1. Project Configuration

Insert the Google Services plugin in your root build.gradle file:

buildscript {
    dependencies {
        classpath 'com.google.gms:google-services:3.1.1'
    }
}

2. App-Level Dependencies

In your module-level build.gradle, ensure to add the Google Services plugin and required dependencies:

apply plugin: 'com.android.application'

dependencies {
    implementation 'com.google.android.gms:play-services:11.8.0'
    implementation 'org.chat21.android:chat21:1.0.10'
    implementation 'com.vanniktech:emoji-ios:0.5.1'
}
apply plugin: 'com.google.gms.google-services'

3. Custom Application Class

Create a custom application class to manage MultiDex:

public class AppContext extends Application {
    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
    }
}

4. Chat Initialization

Set up the chat configuration:

ChatManager.Configuration mChatConfiguration = 
    new ChatManager.Configuration.Builder(APP_ID)
        .firebaseUrl(FIREBASE_DATABASE_URL)
        .storageBucket(STORAGE_BUCKET)
        .build();
ChatManager.start(CONTEXT, mChatConfiguration, LOGGED_USER);

Replace the placeholders with your actual Firebase configuration values.

Understanding the Code through an Analogy

Think of setting up Chat21 as preparing for a big party:

• First, you need a venue (Firebase project) to host your guests (users).
• Next, you gather all the essential supplies (SDK libraries) to ensure a smooth event.
• Your custom application class is like assigning a planner to manage the logistics.
• Finally, the chat initialization is akin to welcoming your guests and getting the party atmosphere going!

Troubleshooting Common Issues

If you encounter issues during setup, here are some common problems and solutions:

• Conflicts within com.android.support:

  Solution: Add a resolution strategy in your app build.gradle to manage dependencies.

• MultiDex problems:

  Solution: Ensure multiDexEnabled true is set in your project configuration.

• Theme issues:

  Solution: Check your application’s theme settings to resolve action bar conflicts.
