How to Load Image From URL in Android using Jetpack Compose?

Last Updated : 10 Jun, 2022

Most of the applications in android use images for displaying some useful information within the applications. Images are considered as easy to convey information to the user. An android application uses more than 100 different types of images. So it is not practically possible to add all the images within the application. This will increase the application size and affect the number of downloads of the application. So for handling this case most applications load the images with the help of the image URL. In this article, we will look at how we can load the image from URL 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 the dependency in the dependencies section in build.gradle

Navigate to the Gradle Scripts > build.gradle and add the below dependency in the dependencies section.

implementation("io.coil-kt:coil-compose:2.0.0-rc01")

After adding this dependency simply sync your project to install it.

Step 3: Adding internet permissions in AndroidManifest.xml

Navigate to the app > manifest > AndroidManifest.xml and add below internet permissions in the manifest tag.

XML

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

Step 4: 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.
