CodeAssist - Android IDE

Bu ilova haqida

CodeAssist is an Android IDE for your phone and tablet. Write Kotlin and Java, watch Jetpack Compose previews update as you type, and build, sign and install real Android apps on the device itself. No PC, no cloud build server, no Gradle daemon.

It is a complete Android IDE, not a code playground: open multi-module Android projects, add libraries from Maven, and ship an APK or App Bundle you can install or publish.

Build Android apps on your device
• The whole toolchain runs on your phone: aapt2, the Kotlin compiler, the Java compiler, D8 dexing, packaging and APK signing
• Incremental builds redo only what changed
• Install and launch your app in one tap, then follow its output in Logcat
• Release builds with R8 shrinking, Android App Bundles (AAB) and your own signing key
• Multi-module projects, build variants, ViewBinding, AIDL, KSP (Room, Hilt) and google-services.json for Firebase
• Dependencies from Maven Central and Google's Maven repository, plus local JAR and AAR files
• Import existing Gradle projects, or export yours as a Gradle project to open on a computer

Kotlin and Java code editor
• Code completion that keeps working on half-written code, with automatic imports
• Errors and warnings as you type, with one-tap quick fixes
• Go to definition, implementation and type, symbol search, and readable library sources
• Reformat Code, Optimize Imports, code folding and word wrap
• Android XML completion for layouts, manifests, values and drawables
• A coding keyboard bar for symbols, pinch to zoom, and editor color schemes

Jetpack Compose and layout previews
• @Preview composables render live next to your code and update as you edit
• Preview XML layouts, including your own custom views, without running a build

AI coding assistant
• Describe a change in plain words. The agent reads your project, edits the code, runs a build and shows a diff you can undo
• Use your own key for Anthropic Claude, Google Gemini, OpenAI or OpenRouter, or a compatible gateway. A free Gemini key works
• Attach screenshots, mention files with @, and pick up saved sessions later

Git and GitHub
• Clone, commit, branch, merge, stash and push
• Sign in to GitHub to clone private repositories and open pull requests

Learn and practice
• Interactive Java and Kotlin lessons with exercises that compile and run on your device
• A daily coding challenge with a public leaderboard
• Start from templates and sample apps in the Projects Store, or publish your own

Also included
• Block editor: switch a Java file to Scratch-style blocks and back without losing a character
• Run Java and Kotlin console programs with an interactive console
• A run sandbox that asks before your program uses the network, files or other processes
• Plugins that extend the IDE, including an NDK plugin for C and C++
• Light and dark themes with Material You colors
