まあだいたい Rubotoを使ってRubyでAndroidアプリをかく を追体験しただけなんですが。
まず動機ですが、別にRubyでAndroid appを書きたいわけではないです。やりたいのことは以下のふたつ。
- Ruby REPLからAndroid appを操作することと
- Android appのテストをRubyで書くこと
特にテスト。文字列操作とかリスト操作はRubyのほうが得意なので、得意なことを得意な言語でやれば効率いいんじゃないかと思うわけです。
ruboto setupがコケる
homebrewでandorid sdkをインストールしている場合、ruboto setupがコケます。
$ ruboto setup --target android-19
Java runtime : Found
Java Compiler : Found
Apache ANT : Found
Android Package Installer: Found
Android Emulator : Found
Android SDK Command adb : Found
Android SDK Command dx : Found
Platform SDK android-10 : Not found
!!! Ruboto setup is NOT OK !!!
Android platform SDK for android-10 not found.
Would you like to download and install it? (Y/n):
$ANDROID_HOME/toolsと$ANDROID_HOME/platform-toolsをPATHに追加するといけました。
export PATH="$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools:$PATH"
Hello, woldまで
$ ruboto gen app --package com.example.rubotoexample
$ cd rubotoexample
$ rake install
$ rake start # start the app
これでとりあえずアプリは立ちあがってRUBOTOのロゴがでる。
アプリを書き換える
activity classはこんなの。けっこうゴツイ。
