The author developed a Markdown editor using Google AI Studio, initially intending to create a native Android application but ultimately producing a web app. They discovered a feature in Google AI Studio to build an Android app and crafted a prompt for a Markdown editor resembling Typora. The app includes file management, a WYSIWYG editing view, and keyboard shortcuts, with enhancements for hyperlink insertion and theme customization. The author successfully installed the app on a physical device and tested it on different configurations. They noted limitations in the testing capabilities of AI Studio and faced challenges transferring the project to Android Studio due to unclear instructions. The app is functional and feature-rich, but cannot be publicly shared due to the inclusion of a Google API key. Google has indicated that sharing on the Google Play Store will be possible in the future.
