How to Display Image From Image File Path in Android using Jetpack Compose?

ImageViews are used to display images in different formats within the Android Application. We can display images within our Image View from the image file name, bitmap, drawable file, and the image URL as well. In this article, we will take a look at How to load images from user devices within Image View using the image path within our Android Application 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: 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.
