## What it is
dryrun is a Ruby gem CLI tool that clones any Android library's GitHub repository, builds its demo project with Gradle, and installs it on a connected device. It lets developers try out Android libraries instantly without manually downloading, importing, and syncing projects in Android Studio.

## Use cases
- try an android library demo without opening android studio
- quickly test a github android library on my phone
- run the sample app of an android library from the command line
- evaluate android libraries before adding them to my project
- test a specific branch or tag of an android library
- run an android library demo with a custom flavor or module

## When to choose
- you want to quickly evaluate an Android library's demo app on a device
- you want to avoid the manual clone-import-sync-run cycle in Android Studio
- you need to test a specific branch, tag, flavor, or module of a library

## When to avoid
- you need deep debugging or editing of the library source in an IDE
- you don't have the Android SDK and Gradle environment set up
- you're working on non-Android projects

## Facets
- artifact type: cli-tool
- maturity: active
- function: developer-tools, cli, build-tool
- domain: android-tools, mobile-development, developer-tools
- platform: cli, windows
- tags: android, gradle, ruby-gem, library-testing, demo-app, command-line, macos, linux
