How to Build a ChatGPT Like App in Android using OpenAI API?

Chat GPT is nowadays one of the famous AI tools which are like a chatbot. This chatbot answers all the queries which are sent to it. In this article, we will be building a simple ChatGPT-like android application by integrating the OpenAI API(ChatGPT) where we can ask any question and get an appropriate answer.

We have created a sample application and will take a look at its output of it and then we will proceed further to creating a new project in android studio. 

Step-By-Step Implementation

Step 1: Create a New Project in Android Studio

To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. Note that select Kotlin as the programming language.

Step 2: Add the below dependency in your build.gradle file

Below is the dependency for Volley which we will be using to get the data from API. For adding this dependency navigate to the app > Gradle Scripts > build.gradle(app) and add the below dependency in the dependencies section. We have used the Picasso dependency for image loading from the URL.  

// below line is used for volley library
implementation ‘com.android.volley:volley:1.2.0’

After adding this dependency sync your project and now move toward the AndroidManifest.xml part.  

Step 3: Adding permissions to the internet in the AndroidManifest.xml file

Navigate to the app > AndroidManifest.xml and add the below code to it. 

Step 4: Working with the activity_main.xml file

Navigate to the app > res > layout > activity_main.xml and add the below code to that file. Below is the code for the activity_main.xml file. 

Step 5: Generating bearer token for using the API. 

Navigate to the below URL and simply sign up with your email and password. On this screen click on Create a new secret key to generate your new key. Once your key is generated that we have to use it as a token for making our API key.

Step 6: Working with MainActivity.kt file. 

Navigate to app > java > your app's package name > MainActivity.kt file and add the below code to it. Comments are added in the code to get to know it in detail. 

Output:
