Website-to-APK Converter

A simple tool to convert any website into an Android APK without requiring Android Studio or Java programming knowledge. The app acts as a WebView wrapper around your chosen website.

Features

• Simple command-line interface with colorful output
• Automatic Java 17 downloading option
• Automated Android SDK tools installation
• APK signing and building process

Quick Start

1. Clone this repository:

git clone https://github.com/Jipok/website-to-apk
cd website-to-apk

2. Create a configuration file webapk.conf:

id = myapp                          # Application ID (will be com.myapp.webtoapk)
name = My App Name                  # Display name of the app
mainURL = https://example.com       # Target website URL
icon = example.png                  # Path to your app icon (PNG format)

allowSubdomains = true              # Allow navigation between example.com and sub.example.com
requireDoubleBackToExit = true      # Require double back press to exit app

enableExternalLinks = true          # Allow/block external links
openExternalLinksInBrowser = true   # If allowed: open external links in browser or WebView
confirmOpenInBrowser = true         # Show confirmation before opening external browser

3. Generate signing key (only needed once, keep the generated file safe):

./make.sh keygen

4. Apply configuration and build:

./make.sh build

The final APK will be created in the current directory.

Available Commands

• ./make.sh build - Apply configuration and build
• ./make.sh keygen - Generate signing key
• ./make.sh test - Install and test APK on connected device
• ./make.sh clean - Clean build files
• ./make.sh apply_config - Apply settings from configuration file
• ./make.sh apk - Build signed APK
• ./make.sh get_tools - Download Android command-line tools
• ./make.sh get_java - Download OpenJDK 17 locally

App Links / Deep Links

You can make your app handle links to the website by setting the deeplink option in your configuration file. When set, clicking links to your website on the device will open them in your app instead of a browser.

For example, if your website is https://example.com, set:

deeplink = example.com

Userscripts Support

The app supports userscripts (similar to Tampermonkey/Violentmonkey scripts) through the scripts configuration option:

scripts = scripts/*.js             # Load all .js files from scripts directory
# OR
scripts = site-*.js                # Load all files matching pattern
# OR
scripts = script1*.js script20.js  # Load specific script files

How Userscripts Work

• Scripts can use Tampermonkey/Violentmonkey/etc @match and @run-at directives, other ignored
• If no @match is specified, the script will run on all pages
• Only GM_addStyle supported from Greasemonkey API
• There are toast("short message") function
• Script console output (console.log/alert/warn) can be monitored using:

./make.sh test

Common use cases include:

• Adding dark mode to websites
• Customizing website appearance
• Adding new functionality
• Fixing mobile compatibility issues

Example of some useful scripts:

• dark-mode.js - Universal dark theme that respects system preferences
• instant.js - Speed up page loads by preloading pages when the user taps

Additional WebView Options

The following advanced options can also be configured:

cookies = "key1=value1; key2=value2"  # Cookies for mainURL
JSEnabled = true                      # Enable JavaScript execution
JSCanOpenWindowsAutomatically = true  # Allow JS to open new windows/popups

DomStorageEnabled = true              # Enable HTML5 DOM storage
DatabaseEnabled = true                # Enable HTML5 Web SQL Database
SavePassword = true                   # Allow saving passwords in WebView
AllowFileAccess = true
AllowFileAccessFromFileURLs = true

MediaPlaybackRequiresUserGesture = false # Disable autoplay of media files
