How it works

• When you press "Build", the app copies a folder called CATGAME from the assets folder to the cache directory.
• • CATGAME.apk is a fork of Pocket Code that skips the main menu and loads the project right away (source code can be found at https://github.com/consler/CATGAME).
• • The CATGAME folder is simply an unzipped CATGAME (you can rename any .apk to .zip and extract it like a normal archive).
• The app then copies your .catrobat file and extracts it to CATGAME/assets/CATGAME, because that's the folder CATGAME loads (.catrobat files are also renamed zip archives with your project data).
• After that, Cat The Builder replaces the default icon with your custom icon.
• Then it zips the CATGAME folder and saves it to the cache directory as CATGAME.apk.
• It uses ARSCLib to change the app name, package name, version name, and version code.
• Finally, it signs the apk and exports it onto your phone's storage.

Note

• Cat The Builder is NOT affiliated with Pocket Code.
• Cat The Builder is made for only Pocket Code projects.
• Cat The Builder is developed by just one person, making the development process quite slow.
• The project is close to a 1.0 release, and any bugs found should be reported.
• If you are fluent in a language that's not English, Ukrainian, Russian or German and are willing to help to add it to Cat The Builder, please contact me.
