以下, StackOverflowからの抜粋.

The Google APIs Client Library for Java is as the name suggests a library for accessing Google APIs and it is available for several platforms such as Java (in general) and Android while the Google Play Services and GoogleAuthUtil is only available on Android.

Google APIs Client Library
→ 汎用的 Java向け (Androidも含む)

GoogleAuthUtil(Google Play services)
→ Android向け専用

However if you dig into the code and their issue tracker a bit you can see that the tasks sample you linked actually uses GoogleAuthUtil since version 1.12.0 of the Google APIs Client Library when support for GoogleAuthUtil was added.

Google APIs Client Library バージョン 1.12.0 移行は GoogleAuthUtil が追加されている.

AccountManager.getAuthToken

良いとこ:
- OS 2.0+ から使える.
- Android自体に含まれていて,別SDKを必要としない.
- 認証をもつすべてのアカウント(Google以外でも)で使える.

悪いとこ:
- トークンが期限切れなら再度新しいトークンを取得.
- GET_ACCOUNTS と USE_CREDENTIALS のパーミッションを必要とする.
- 認証要求画面が 2.x でダサい.

GoogleAuthUtil.getToken

良いとこ:
- 常に使えるトークンを返す.
- パーミッションは GET_ACCOUNTS のみ.
- 認証要求画面がダサくない
- Google が推奨している.

悪いとこ:
- 2.2+ の GooglePlay利用のデバイスに限る.
- Google Play services SDK が必要.
- Google API Console からアプリ登録が必要.
- Google services での OAuth 2.0 のみ.

Xcode アップデートで Android Studio から git が使えない

MacOSのアップデートの後, AndroidStudio にてこんなダイアログ.

cannot_git

Can't start Git: /usr/bin/git
Probably the path to Git executable is not valid.

見えてない?


$ which git
