## What it is
Ruboto is a framework and toolchain for developing native Android apps in Ruby via JRuby, integrating with Android Studio and Gradle workflows. It includes a CLI for project setup, code generation, and deployment to devices or emulators.

## Use cases
- write android apps in ruby
- develop native android apps with jruby
- access android java api from ruby
- set up a ruby android project with gradle
- deploy ruby android app to device or emulator
- run a ruby repl on android

## When to choose
- you know Ruby well and want to build Android apps without learning Java or Kotlin
- you want full access to Android's Java APIs from Ruby code
- you prefer scripting rapid app iterations with hot deployment

## When to avoid
- you need a mainstream, actively maintained mobile stack with large community support
- your project requires the latest Android APIs or broad device compatibility
- you need maximum app performance or small APK size
- you are starting a new production app - the project is in maintenance mode with infrequent releases
