Android CLI Specialist

This skill provides instructions for using the android CLI tool. The tool includes various commands for creating projects, running applications, interacting with devices, and managing the CLI environment.

Installation

If the android tool is not in the path, install it. To install run the following command: Linux: curl -fsSL https://dl.google.com/android/cli/latest/linux_x86_64/install.sh | bash Mac Arm: curl -fsSL https://dl.google.com/android/cli/latest/darwin_arm64/install.sh | bash Mac Intel: curl -fsSL https://dl.google.com/android/cli/latest/darwin_x86_64/install.sh | bash Windows: curl -fsSL https://dl.google.com/android/cli/latest/windows_x86_64/install.cmd -o "%TEMP%\i.cmd" && "%TEMP%\i.cmd"

SDK management

To manage the installation of Android SDKs and tools, use the sdk command. For example:

• android sdk install <package>[@<version>]...: Install specific packages. Multiple packages can be specified, separated by spaces. <version> defaults to latest. For example: android sdk install platforms/android-30@2 platforms/android-34
• android sdk update [<pkg-name>]: Update a specific package or all packages to the latest version.
• android sdk remove <pkg-name>: Remove a package from the local SDK.
• android sdk list --all: List installed and available SDK packages.

Project creation

Create projects from templates using the create command.

For example: android create empty-activity --name="My App" --output=./my-app

Interacting with devices

For more information on interacting with running devices, see here

Running journey tests

Doc searching

The docs command searches authoritative, high-quality Android developer documentation in the Android Knowledge Base. By providing a few keywords, this tool will return high quality articles that contain examples or guidance on how to use Android APIs or libraries. Use this tool to obtain additional information on how to achieve Android-specific tasks or to know more about Android APIs, surfaces, libraries, or devices.

Always use this tool to get the most up-to-date information about Android concepts. Typical good use cases are:

• Finding migration guides for APIs.
• Finding examples for APIs.
• Finding up-to-date information about Android APIs.
• Finding best practices for Android concepts.

Running APKs

Use the run command to run Android apps.

Managing emulators

Manage Android Virtual Devices (AVDs) using the android emulator command

Capturing screenshots

Capture an image of the current screen of a connected Android device and output it to a file using the android screenshot command.

Managing skills

Manage agent skills for Android using the android skills command.

Inspecting UI Layouts

Use the android layout command to inspect the UI layout of an Android application. It returns the layout tree of an Android application in JSON format. When debugging UI errors, this is often a much faster approach than taking a screenshot.

Updating the CLI

Update the Android CLI using the android update command.

android help output

Usage: android [-hvV] [--sdk=PARAM] [COMMAND] -h, --help Show this help message and exit. --sdk=PARAM Path to the Android SDK -v, --verbose Enable verbose output for troubleshooting -V, --version Print version information and exit. Commands: create Create a new Android project from available templates. Allows specifying project name, output directory, minSdk, and dry-run execution. describe Analyzes an Android project to generate descriptive metadata. docs Android documentation commands for searching and fetching developer documentation from the official knowledge base. emulator Manage Android Virtual Devices (AVDs). Includes commands to start, stop, list, and view details about emulators. help Shows the help of all commands info Print environment information including SDK location, connected devices, and configuration variables. Use specific fields to narrow the output. init Initializes the environment for the Android CLI. Sets up required configurations, directories, and default skills. install Install an Android Application (one or more APKs) to a connected device or emulator without activating any components using incremental optimizations for faster deployment than adb. layout Returns the layout tree of an application run Build, deploy, and launch an Android application on a connected device or emulator. screen Commands to view the device sdk Manage the Android SDK installation.
