In this tutorial, we will be building a basic android chat app using Applozic SDK in android studio.

Prerequisites

1. Applozic account

2. Android Studio 2.x and above

3. Gradle 3.1.3 and above

4. JDK 8.0 /Language

5. Android app(If you already have your own, it’s fine or download it here)

There are 5 simple steps to build an android chat app.

1. Get your free chat starter kit

2. Install Applozic chat SDK in your android app

3. Configuration

4. Authentication

5. Check if the user is already logged in

Let’s start with getting the free chat starter kit

Step 1: Get your free chat starter kit

We will be using Applozic free chat kit to build our chat app.

Applozic chat kit includes

1. Ready-made Chat SDK

2. Chat API

3. Ready-made UX/UI,

To get this free chat kit, Sign up here and once you signup Applozic generates unique APP_ID which we will be using it in our configuration step.

(You can get APP_ID in the installation section)

Step 2: Install Applozic chat SDK in your android app

Once you create applozic a/c then you need to integrate Applozic chat SDK in your app.

Here you will be using the Gradle toolkit to integrate the chat app.

(What is Gradle in android studio)

Copy the below and add it in your android Gradle dependency

implementation 'com.applozic.communication.uiwidget:mobicomkitui:5.45'
          

Once gradle is build, you need to exclude a package option to avoid duplicate files or errors.

To exclude package, Just copy the below and add it in your grade android target.

Your build. gradle file will look like this: Great! Now you’re done with the installation of Chat SDK into the android app.

Let’s get into the third step

Step 3: Configuration

In this step, you need to CONFIGURE the activity and metadata in your AndroidManifest.xml and put your APP_ID, app icon and attachment folder name. This step is needed because there are some components used by Applozic SDK which needs to be registered in your App-level AndroidManifest.xml file just that you can change their properties. For e.g, you need to add the ConversationActivity.java entry in the AndroidManifest.xml file to add a parent activity(Which belongs to your app) to it.

Add below coding within your android App application tag.


NOTE: Do NOT change this, it should remain same i.e ‘com.package.name’ →

You AndroidManifest.xml file will look something like this:

Step 4: Authentication

(You need to make sure that you have already created the a/c in applozic)

Login into Applozic Chat – user registration code – anywhere from your app – pass the required details.

Before accessing any APIs or Screens in Applozic SDK, you need to authenticate a user. You can directly authenticate a user using a userId (The only mandatory field of Applozic User), if the user exists, the SDK will log in the user, if not, the SDK will create the user and login. Do the following operations in LoginActivity.

Create a User object as below:



This is how the Login Activity will look:

Step 5: Check if the user is already logged in

In your launcher activity(In this sample, MainActivity) you can check if the user is already logged into applozic, if the user is already logged in, launch the chat directly with a userId “test2” (You can use any userId), else we will navigate the user to the login activity.

In your launcher activity’s onCreate() method, add the below code:


This is how the launcher activity will look like:



Here’s How the chat window will look like:
