Many times while building an android application we integrate payments within our android application. While making the payments we also want to get bank details from the user such as bank name and others. IFSC Code of any bank provides all the details of that specific bank. In this article, we will take a look at How to get Bank Details from IFSC code in Android using Jetpack Compose.

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. While choosing the template, select Empty Compose Activity. If you do not find this template, try upgrading the Android Studio to the latest version. We demonstrated the application in Kotlin, so make sure you select Kotlin as the primary language while creating a New Project.

Step 2: Adding dependency for using Volley

Navigate to app > Gradle Scripts > build.gradle file and add the below dependency to it. Comments are added to the code.

// dependency for volley
implementation 'com.android.volley:volley:1.2.0'

Now syn your project to install the dependency.

Step 3: Adding a new color to the Color.kt file

Navigate to app > java > your app’s package name > ui.theme > Color.kt file and add the below code to it.

Kotlin




package com.example.newcanaryproject.ui.theme
 
import androidx.compose.ui.graphics.Color
 
val Purple200 = Color(0xFF0F9D58)
val Purple500 = Color(0xFF0F9D58)
val Purple700 = Color(0xFF3700B3)
val Teal200 = Color(0xFF03DAC5)
 
// on below line we are adding different colors.
val greenColor = Color(0xFF0F9D58)


Step 4: Adding permissions to the internet in the AndroidManifest.xml file

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

XML




<!--permissions for INTERNET-->
<uses-permission android:name="android.permission.INTERNET"/>


Step 5: Working with the MainActivity.kt file

Go to the MainActivity.kt file and refer to the following code. Below is the code for the MainActivity.kt file. Comments are added inside the code to understand the code in more detail.

Kotlin




package com.example.testproject
 
import android.annotation.SuppressLint
