Provide a ready-to-use Android development environment image

[hubowi]

Hello Dev Container Maintainers,

First, thank you for the great work on providing these official development container images. They are incredibly helpful for standardizing development environments.

I'm writing to request a feature that I believe would benefit many developers: a dedicated, pre-configured Dev Container image for Android application development.

Currently, developers who need to build Android apps in a containerized environment (like GitHub Codespaces or local Dev Containers) often have to combine a base image (e.g., mcr.microsoft.com/devcontainers/base:ubuntu) with several features. While this works, it requires manual configuration of the Android SDK, command-line tools, build-tools, platform versions, emulator support, and acceptance of licenses. This process can be time-consuming, error-prone, and challenging to keep consistent across teams.

Proposal:
Create and publish an official mcr.microsoft.com/devcontainers/android image (or a similarly named variant under the src/ directory). This image should aim to provide a batteries-included environment for Android development, similar to the excellent language-specific images you already offer (like javascript-node or python).

Suggested Core Components:

1. Base: A recent LTS version of Ubuntu.
2. Android SDK: The core SDK, command-line tools, and a set of commonly used build-tools and platforms (e.g., the latest stable versions).
3. Essential Tools: adb, fastboot, and necessary system libraries for running the emulator or connecting to physical devices.
4. Licenses: Pre-accepted Android SDK licenses to enable seamless, non-interactive setup.
5. Common Dependencies: git, curl, wget, unzip, and other utilities commonly needed in build scripts.

Potential Configuration Options:
The image could be made more flexible by allowing users to specify desired Android components via build arguments or a companion Dev Container Feature, enabling customization of SDK versions, NDK inclusion, etc.

Benefits:

· Faster Onboarding: New contributors or CI/CD systems can get a working Android build environment in minutes.
· Improved Consistency: Eliminates "it works on my machine" issues by providing a single, versioned, canonical environment.
· Reduced Complexity: Simplifies devcontainer.json files for Android projects, making them easier to maintain.

I understand this is a non-trivial request. If creating a full image is not immediately feasible, perhaps a comprehensive, official "Android SDK" Feature (published to ghcr.io/devcontainers/features) that robustly handles all setup steps would be a great first step.

I would be happy to help test any prototypes or provide more detailed feedback. Thank you for considering this request.
