Compose WebView Part 4 | OFFLINE Load from Assets folder

We learn online webview to load a webpage/website from URL online. We can also load a webpage from the assets folder in jetpack compose webview. 

You can provide web-based content—such as HTML, JavaScript, and CSS—for your app to use that you statically compile into the application rather than fetch over the internet.

This example demonstrates how do I load files from asset directory into WebView in android.

Step 1:

To add text-based web files to a project, do the following:

  1. In Android Studio, right-click the app > src > main folder and then choose New > Directory.

    Screen showing create-directory menus
    Figure 1. Create an assets folder for your project.

  2. Name the folder "assets."

    Screen showing directory-naming dialog
    Figure 2. Name the assets folder.

  3. Right-click the assets folder and then click New > File. Enter index.html and press Return or Enter.

    Screen showing create-file menus
    Figure 3. Create files with the name of the following code samples.

  4. Fill in the empty files with the web files (Html, CSS, JS).
