Step by step guide to build apk using capacitor from URL

Prerequisites

• Node.js and npm (or yarn):
  Make sure you have Node.js and npm (Node Package Manager) or yarn installed on your system.
  You can check by running:

  node -v
  npm -v
  # or
  yarn --version

• Android Studio:
  You'll need Android Studio installed to build and run the Android app on an emulator or a physical device.

Steps

1. Create a New Capacitor Project

Open your terminal in the directory where you want to create your project and run:

npm init @capacitor/app

The CLI will ask you a few questions:

• App name: Choose a name for your app (e.g., MiningApp)
• Package ID: This is your app's unique identifier (e.g., com.example.miningapp)
• Web dir: Enter . (dot), since your portfolio is already a built website hosted on Vercel

After answering the questions, Capacitor will initialize a basic project structure.

---

2. Add the Android Platform

Navigate into your newly created project directory:

cd MiningApp

Then add the Android platform:

npm install @capacitor/android
npx cap add android 
or
.\node_modules\.bin\cap add android

This command will download the necessary Android dependencies and create an android folder in your project.

PS D:\New folder\dmsvs_app> npx cap sync android
[warn] Cannot copy web assets from non-existent-folder to android\app\src\main\assets\public
       Web asset directory specified by webDir does not exist. This is not an error because server.url is set in config.

√ Updating Android plugins in 2.29ms
[info] Found 2 Capacitor plugins for android:

       @capacitor/splash-screen@7.0.1
× update android - failed!
[error] Error: ENOENT: no such file or directory, open 'D:\New
        folder\dmsvs_app\android\app\src\main\assets\capacitor.plugins.json'

The error Cannot copy web assets from non-existent-folder to android\app\src\main\assets\public occurs cuz it's not exist in the directory .

To solve that you need to just create android\app\src\main\assets\public

The error occurs cuz there no such file as 'D:\New folder\dmsvs_app\android\app\src\main\assets\capacitor.config.json' exist in the diectory.

To solve that issue you have to create a file in the diectory as 'D:\New folder\dmsvs_app\android\app\src\main\assets\capacitor.config.json', and copy the content in the existing capacitor.config.json into the 'D:\New folder\dmsvs_app\android\app\src\main\assets\capacitor.config.json'

3. Configure the capacitor.config.ts File

Open the capacitor.config.ts file in your project’s root directory and modify it:

import { CapacitorConfig } from '@capacitor/cli';

const config: CapacitorConfig = {
  appId: 'com.example.miningapp', // Make sure this matches what you entered during initialization
  appName: 'MiningApp',
  webDir: '.', // Changed to '.' to point to the root where your website "is"
  bundledWebRuntime: false, // Since your website is hosted, we don't need to bundle a web runtime

  // Optional: Configure the server URL
  server: {
    url: 'https://dmsvspz.web.app/',
    cleartext: true // May be needed for development if you encounter issues with HTTPS
  }
};

export default config;

Explanation:

• webDir: '.': Points to the root directory where your website resides.
• bundledWebRuntime: false: Disables bundling since your site is already hosted.
• server.url: Tells Capacitor’s WebView what URL to load.
• server.cleartext: true: Useful for development if HTTPS issues occur.

4. Sync Capacitor

After configuration, sync your project:

npx cap sync android

This will update the Android project with your settings.

---

5. Open the Android Project in Android Studio

npx cap open android

This command opens the android folder in Android Studio.

---

6. Run Your App

In Android Studio:

• Build: Go to Build > Make Project
• Run: Click the green "Run" button or go to Run > Run 'app'
• Select Device: Choose a connected physical Android device or emulator

Your app should now launch and display your portfolio website.

---

Important Considerations

• Internet Permission:
  Capacitor automatically adds the required permission.

• Responsiveness:
  Make sure your site is mobile-friendly.

• Native Features:
  For native features like camera or GPS, use Capacitor Plugins.

• App Icon and Splash Screen:
  Customize these in android/app/src/main/res.

• Build for Production:
  Use Android Studio tools to generate a release APK or AAB for distribution.
