CodeAssist: An IDE for Building Android Apps on Android
CodeAssist is an IDE that runs on Android phones, supporting Kotlin/Java editing, Compose and XML layout previews, and on-device build, sign and install of APKs without a computer or remote build server. It uses its own project model instead of Gradle, supports multi-module projects, build variants, KSP, Git operations and an optional bring-your-own-key AI coding agent, with desktop builds for Windows and Linux. Limitations include no Gradle plugin execution, newer and rougher Kotlin support, and slow indexing/building of large projects on low-RAM phones.
What this means for indie developers：Indie developers who need to edit code, produce test builds or prototype on the go can try this open-source tool directly, though complex Gradle projects still require Android Studio.
