Release 1 of Code on the Go brings core IDE features like full Kotlin language support, a graphical Git interface, a stronger plugin system, and improved UI layouts to a phone-based Android development environment. The update focuses on making serious Android app development practical on a phone, while adapting to different hardware setups such as tablets, external monitors, and limited connectivity.

Code on the Go’s Sketch to UI feature lets developers draw a rough app layout on paper, photograph it, and instantly generate usable Android XML. All entirely offline on a phone. It achieves this through a lightweight, on-device pipeline combining structured sketch input, boundary detection, widget recognition, and OCR with fuzzy matching to translate messy handwritten designs into functional UI code.

Code on the Go’s plugin system brings desktop-style extensibility to a mobile IDE, giving developers a lightweight, customizable environment that fits the tight resource limits of a phone. Its secure, isolated design ensures plugins can add powerful features without risking performance or stability.

Code on the Go (CoGo) replaces the traditional workstation-dependent debugging model by consolidating the entire Android development stack onto a single mobile device. To make this possible, we engineered a new on-device debugging stack that securely bootstraps privileged access, and works only on the phone you use with Code on the Go. Come see how we did it!

Kotlin is now supported in Code on the Go, bringing the same real-time code intelligence Android developers expect from desktop IDEs (including completions, inline error diagnostics, and go-to-definitions) all running locally on your Android device. Find out about the technical decisions that made it possible to deliver responsive language tooling within the constraints of a phone-based IDE.

App Dev for All is collaborating with the Internet in a Box (IIAB) project to bring offline knowledge libraries to Android devices through an integration with Code on the Go. The result transforms an ordinary phone into a portable server that can deliver educational content and enable local Android app development—even where reliable internet access is limited.

Gemini integration into Code on the Go enables professional-grade software architecture by introducing a collaborative AI agent to help analyze and revise your code.

Our support for 32-bit and 64-bit ARM architectures ensures that professional-grade coding tools are accessible to millions of developers using legacy hardware while still delivering high-performance optimization for modern devices. This inclusive approach reinforces our mission to remove hardware as a barrier to entry, ensuring that opportunity is never gated by the cost or age of a user’s smartphone.

Android has historically been open, but Google has other plans. From mandatory fees to the end of anonymous app distribution, the new developer verification rules are a direct strike against the free and open-source software community.

The most efficient code is the code you never write. When that doesn’t solve the problem, how do you balance the need for a quick solution against the possible future need to recreate it?

If you’ve been building Android UI with Jetpack Compose, you already know it’s a fundamentally better way to build interfaces: declarative, elegant, and fast. Code on the Go’s Jetpack Compose Preview feature now lets you view your Compose UI on the

If you’ve ever tried to port a high-performance library to Android and hit a wall, that wall is now lower with Code on the Go’s new Native Development Kit (NDK) support.

IDEs are big. Older phones are small. How can we make this work?
