Notes, boards and cloud machines for app development.
Android apps built with a coding agent
A coding agent builds an Android project with Gradle on a Linux cloud machine. The APK downloads for testing on an Android device outside the codespace. The first screen and its action provide a scope for review before further screens are added. Emulator testing and Google Play publishing are outside this workflow.

First screens and local or backend data
A first screen can provide a list to browse, a detail view to read or a form that saves something. The brief records whether its data stays on the device or comes from a backend. This gives the first build a defined action and a way to check the result before additional screens expand the app. The data decision remains part of that review.
A kanban card holds the screen, its action and the data decision. A small first card can be checked in a single pass against the brief. The next screen becomes a further task once the agent’s result has been reviewed against the intended behavior.
Defined actions in a Gradle project
The task specifies an Android project that builds with Gradle and the exact action needed by the screen. Examples include saving an entry to local storage or calling an endpoint and listing its results. A concrete action defines what the agent implements and what the build needs to support.
The codespace runs Linux with a terminal and VS Code in the browser. Claude Code, Codex CLI, opencode, Cursor CLI, Antigravity and Qwen Code work there with supplied sign-ins or API keys. The Android SDK command-line tools and Gradle version required by the project can be installed on the machine.
APK review on an external Android device
This workflow does not run an emulator or a connected device inside the codespace, and it does not publish to Google Play. Gradle output is available in the terminal. The built APK downloads from the codespace for installation on an Android device, where the screen can be checked against the brief.
The codespace is billed by the hour while it runs. A snapshot supports stopping the machine and returning later; snapshot storage is billed monthly in credits. The board can record anything needing further review after the APK has been checked on the device.
Questions about android apps built with a coding agent
- What should a first version of an Android app include?
- One screen with a real action can provide the first scope, such as a list, a detail view or a form that saves something. The brief records whether its data stays on the device or comes from a backend.
- Do I need Android Studio installed?
- The coding agent builds the Android project with Gradle in the codespace terminal. This workflow does not run an emulator or a connected device, and it does not publish to Google Play.
- How do I check the build without an emulator?
- Read the Gradle build output in the codespace terminal, then download the built APK to your own Android device and install it there to check the result against your brief.
