Hello, Welcome to the feel and question.
Here is a quick way do it out!
Build the Next.js project: Run the build command for your Next.js project, which typically generates a production-ready build in the “out”/ “build” folder.
npx next build && npx next exportLocate the build output: Once the build process is finished, locate the generated “out” folder in your Next.js project directory.
Copy the build output: Copy the entire contents of the “out” folder, including any subfolders and files.
Paste the build output in the Android project: Navigate to the root directory of your Android project in Capacitor. The default location is usually the “android” folder within your Capacitor project.
Paste the build output: Paste the contents of the “out” folder into the appropriate location in your Android project. By default, you can paste it into the “app/src/main/assets/public” directory of your Android project.
Sync the Android project: After pasting the build output, trigger a sync operation in Android Studio to ensure the changes are recognized. This can be done by clicking on the “Sync Project with Gradle Files” button or by selecting “File” -> “Sync Project with Gradle Files” in the Android Studio menu.
Build and run the Android project: Once the sync operation is complete, you can build and run your Android project to deploy the updated Next.js web application within your Capacitor app.
Voila you are done!.
