Android Studioを入れずにAndroid SDKをインストールする方法(Mac)

## はじめに

Android StudioをインストールするとAndroid SDKも同時にインストールされます。
しかし、私はIntelliJ IDEAを使いたいため、Android StudioをインストールせずにAndroid SDK Toolsからコマンドラインでインストールすることにします。

SDKMANを使ってインストールできたら便利だと思ったのですが、2018/04/05現在ではできませんでした。

## 環境

- OS：macOS High Sierra 10.13.1
- Android SDK Tools：26.0.1

## Android SDK Toolsのインストール

Android Studioの公式サイトからダウンロードします。
「コマンドライン ツールのみ入手する」から対象プラットフォームの「SDK ツールパッケージ」をクリックします。
https://developer.android.com/studio/index.html

「上記の利用規約を読み、同意します。」チェックをONにし、「SDK-TOOLS-DARWIN-3859397.ZIP ダウンロード」をクリックします。

ダウンロードには時間がかかります。

ダウンロードが完了したら解凍してスペースが含まれていないパスに配置します。
~~私は `/opt` に配置しました。~~
`/opt` は管理者権限が必要なため、 `/usr/local/opt` に `android-sdk` フォルダを作成してその直下に配置しました。
配置先のフォルダに権限が不足していると、Android SDKのインストール時に `Warning: Failed to read or create install properties file.` エラーが出るので注意してください。

Android SDK Toolsのパスを通すため、 `.bash_profile` に以下を追記します。

```bash:.bash_profile
# Android SDK Tools
if [ -d "/usr/local/opt/android-sdk/tools/bin" ]; then
  export PATH=$PATH:/usr/local/opt/android-sdk/tools/bin
fi
```

これでAndroid SDK Toolsのインストールは完了です。

## Android SDKのインストール

$ sdkmanager --list

`Warning: File /Users/{ユーザー名}/.android/repositories.cfg could not be loaded.` 警告が出力されています。
以下の記事の通りに設定ファイルを作成すれば警告が出なくなります。
