What is it?

Cosmic IDE turns an Android device into a development environment. It combines a code editor with language servers for Java, Kotlin, Scala, Rust, C/C++, Python, and other languages, along with build tools such as Gradle, Maven, Cargo, CMake, and npm.

The app includes an interactive Linux terminal with job control and a pacman package manager for installing compilers and tools. A dedicated Git interface handles staging, commit history, branch switching, and push/pull, and JDKs can be downloaded and switched from settings via Foojay.

The editor supports multi-tab editing, syntax themes including custom TextMate themes, and side-by-side previews for Markdown, HTML, and images. Plugins extend build systems and project templates, and any stdio language server can be added with custom starter scripts.
